Vortrag “Volocopter – Der erste grüne Hubschrauber der Welt”

August 11, 2019

Get in the Volocopter and make yourself comfortable in the cockpit You press the main switch, the display of the on-board computer welcomes you and shows a complete status report on
the condition of the device No sound is yet to be heard.
Slowly you push the thrust lever forward The electric motors start softly
to whir You just hover above the ground A little more thrust and you rise vertically into the sky Now you push the joystick slightly forward The aircraft is picking up speed Easily, you are flying a curve The controller reacts spontaneously and precisely After a trip in the area where you have your place more closely viewed from above you get to the point exactly where you started The wings are quickly folded and the Volocopter parked back in the garage Just plug in to recharge the battery in a short time on your own solar system I have formulated this vision in autumn 2010 These were my thoughts that started the whole project I got to know Stephan Wolf via the internet and we have decided
we just build a prototype from a vertically take-off and landing aircraft, driven purely by electric motors So we met and then Decided in early 2011, okay we’ll do that now After half a year of construction, we have created this prototype so it did not take long So we did the first manned flight with it This Volocopter has 16 rotors This is the first prototype to be driven purely electrically we also did a few unmanned load tests before that but after it was clear, everything worked I said, ok, I sit in there now and I fly with it the whole thing is controlled with
a model remote control I have the remote control hanging around my neck and So I myself sitting in there controlled me with the model remote control This flight took a minute and a half. I did not fly up that was purely to show that
Principle works Then it went around first. the
worldwide coverage turned over Our video was in the first one
Week already clicked a million times and by now it’s almost ten
Millions of times that the video was viewed I am particularly proud of the Lindbergh Innovation Award left to see the Erik Lindbergh the grandson of Charles Lindbergh,
the famous Atlantic Overpasser There are occasional projects
excellent, which are particularly innovative and have to do with electric propulsion in aviation Also an entry in the Guinness Book of
At some point we noticed records Oops, we’re in the Guinness Book. That was not intended Some people do that yes
on purpose, we were surprised by it A fundamental question when designing such a Rotoflieger is how much rotor surface do I spend on the device If you have a lot of rotor surface
we come out with very little power So this muscle power helicopter or multicopter can do that with 500 watts to raise a man in the air That’s a very low performance. He occupies just a whole gym and it has to be absolutely calm, otherwise it will be blown away This is the end of the
Spectrum, what you can achieve with extreme lightweight construction and with one
corresponding design with large rotor surface On the other hand, there are these jetpacks, which also work with rotor drives, but only have a very small rotor surface As a result, they need a tremendous performance. So you need 150 kW to float with such a jetpack. So that means you have to have a correspondingly powerful drive there Everything you save now somehow on the rotor surface and size of the structure, you have to invest in weight in this drive and accordingly stop the amount of fuel, or take electrical energy this means I have some calculations for that
hired and in my opinion now this concept of this Volocopter VC1 is optimal, a practicable, suitable for everyday use
Develop aircraft. With 20 kW of power we can
So stay in the air That is much more than this
Human-powered helicopter but was much less than a jetpack and you have a very good balance between them Weight, power and area in the
ultimately Yes, I think that’s the dream of the flying car that many have dreamed of and that justifies this hype, why we get so much popularity worldwide Right in the picture from the movie “Das
fifth element “, where cars in three dimensions flying through the cities. It is not clear how the drive works probably it’s some sort of antigravity drive As long as we do not have that,
we actually have to resort to aerodynamics And there is actually only a rotor flyer in question Nowadays the rotorflies, the generally accepted ones are the helicopters In such megacities for example as Sao Paolo Anyone who can afford it somehow and has little time flies with the
Helicopter from one house roof to another from one business meeting to the next because the streets are so hopeless
are clogged, that it would take hours to get through it and I’ve read a number about 900 helicopter flights a day in Sao Paolo That makes a lot of noise that consumes a lot of energy that is not very efficient If you can replace these flights with electric-powered flights So that would be a big step forward And that is also a potential market for us from E-Volo At my first lecture here two years ago I have a bit of our ancestors there I do not want to do that today, our historical predecessors Meanwhile we have ourselves
Aviation history written and There are a lot of imitators, so after our first flight then surfaced the company Hyundai always does
such internal tech days where the employees have any
introduce interesting projects and there was presented such a device, which is really striking resembles our VC1 also 16 rotors, which have now been here
still provided with panels the hope is that you can do it
less energy is needed by such disguised propellers I think it’s a milkmaid bill You can also achieve the same effect by simply making the propellers a bit bigger These panels have the crucial disadvantage if you can do it a bit faster
wants to fly then they also do a certain amount
drag and thus the advantage is actually nullified that means we have consciously on
dispense these panels That went through the press about half a year ago A famous singer has put on this device In the background is the pilot and controls with a remote control That took place in a hall.
It was only a short hop I have to say, well, we were there with you
the VC1 actually much further The Chinese are also working on such
projects There you try it with internal combustion engines I do not think he wants to lug the concrete slabs during the flight I think you have not come very high with it A completely different direction of development which partly takes place parallel to our development These are so-called Hoverbikes Basically similar to bicycle or motorcycle-like parts one tries to get by with two drives, with two rotors must then aerodynamically control the whole thing that in turn also has some disadvantages the small rotor area, you also need a lot of power for these devices and the control happens with any flaps that need to be controlled something different working principle than our Volocopter Another project, the renowned company Augusta Westland has run this project Zero as a pure research project I do not know if that was ever in the air that’s a tiltrotor airplane, too
powered by electric motors It was presented at an air show sometime but more details could not be found So, if it ever was in the air, I doubt it What are the advantages of
a Volocopter? He can start and land vertically like a helicopter that is the central point, which one would like to have if you want to fulfill this dream of a flying car In helicopters, the controls are so complicated Because of the different axes, if you steer in one direction then the 90 degrees to offset, phase shifted and you have to balance it all out and get it under control intuitively with us completely everything microcomputer is controlled, that is the position control is done by the computer and you can do it yourself with the joystick just the direction of flight that is, if you want to fly forward, push the joystick forward, If you want to fly sideways, you push it to the side if you want to turn on the spot, turn the joystick so that’s all completely intuitive and
the Volocopter reacts the same way as you would expect By being so easy to fly, is of course also the pilot training
much easier and cheaper There are, due to the nonexistent
Mechanics, virtually no maintenance costs and therefore also very low
operating cost Powered purely by electricity without being exhausted, that’s especially true for Big cities very interesting, where stop
the helicopters are already flying if you can substitute, then
that would be great There is the comparison.
So we really only have Here is a brushless electric motor and there is the propeller screwed directly on it There are no gears, there is no swashplate, blade adjustment, control rods, Butt joints, everything that one
Making helicopters very complex and complex, we do not need that, because
the Volocopter works on a completely different principle The position control becomes pure through the speed adjustment the electric motors accomplished. That is, if you like if you want to fly a left turn, then give the right engines more thrust and thereby
creates a force to the left So that’s a lot easier than a helicopter The VC1, which we at the
Have seen beginning that was a pure for us
feasibility study Of course, many have smiled at us that’s pretty rough, with
Aluminum rods screwed together and riveted and the bouncing ball underneath, that
are all very strange We went further and said, what would a two-seater look like now? if you really are one now
wants to develop the right aircraft what in a microlight category
can be admitted in Germany How should that look? And then we did it again based on existing designs The development goals were above all so also the safest air sports equipment of the
Construct the world how we do that, I will show later no mechanics and easy to fly, we already had. Of course you can not handle such a bigger project alone anymore. In other words, we have searched for suitable partners in industry, research and finally, the authorities that are supposed to allow it The Volocopter VC200, that’s ours
current model, is therefore intended for two people with a take-off weight of 450 kg that means one should also be one
Do not exceed the empty weight of 300 kg that is very demanding, considering that alone the battery weighs almost 100 kg and the rest of the structure with motors and all the trimmings then weigh only 200 kg That’s only possible with state-of-the-art materials, with carbon fiber and so on This new design has 18
Drive units, Each engine provides up to 4.5 kW and then, to stay in the air, we need 45 kW of hover power when fully loaded, we can fly about 20 minutes with it which is quite neat. Of course we hope the batteries will continue to evolve and that we will be in a few years, when we are there in the market then the batteries will be so good that you can reach there also flight times of up to one hour driven purely electrically As with other ultralight aircraft, the Volocopter will also have a total rescue system that is, it’s a parachute that comes with a, Of course, only in an emergency, is shot out by a rocket that’s the last one, so to speak
Rescue anchor before falling from the sky That makes the system even safer This is not possible with helicopters, for example, because there are no bailouts which shoot in the air when the main rotor is still rotating One of our project partners is the university
Stuttgart, the Institute of Aerodynamics and Gas Dynamics IAG they did some simulations for us because that’s the system also been new territory,
So there is a lot to research they have so far researched their work on helicopter rotors and then we arrived. How does it look like when you have 18 rotors now? The whole thing was simulated in the computer. CFD stands for Computer Fluid Dynamics It is basically a finite element method, that is, the whole room is broken up into little cubes You look like these individual volumes of air themselves Behave with the neighboring volumes and influence each other and through many iterations you can then
this equation system that is, which consists of millions of equations. That takes a lot of computing time. So the mainframe computer of the University of Stuttgart was busy for weeks to produce such beautiful pictures which also brought us some new insights So the rotors were designed by the working group in Stuttgart they are designed differently than normal propulsion propellers for airplanes are therefore a complete new development based on the findings that were gained there These CFD simulations with all 18
Rotors, one sees there on the one hand the streamlines but also something like vortex braids. They definitely showed us one or the other, where we can optimize something else The rotor blades themselves were examined both in this composite, as well as individually You have, similar to a helicopter if you fly fast now with the Volocopter, and we want to reach top speeds up to 100 km / h, then there is a leading sheet and a returning sheet that is, this leading leaf is streamed from the air faster than the returning one and that makes it more buoyant That is, at every turn
is there a beating moment Of course you have to identify that first, look how big that is compared to the helicopter it’s relatively small, so we said okay we can really do without flaps this is absorbed solely by the elasticity of the rotor Not just the beating of the leaves, too
the torsion, that is the angle of attack of the leaves changes during each revolution of the rotor, by the way run at about 1600 to 1800 rpm Because of these diagrams you could
then, for example, recognize that you had to reinforce the sheet at certain points a bit more to suppress this twist a bit and achieve those values ​​that you wanted to achieve The pressure distribution across the Volocopter was interesting in several ways On the one hand, you could calculate how much the windscreen is loaded For weight reasons, we said okay, we do not do that one now deep-drawn, very heavy Plexiglas hood
as is usual with gliders, but we do a lot
thinner polycarbonate lens but then only curved two-dimensional can the disc endure the resulting pressure forces at all? Or: where is the optimal point around now
still to accommodate measuring devices, for example a static pressure gauge? As you can see, so here in the nose area is very good place for it So because of all these calculations of the University of Stuttgart, which are still running the dilemma is yes, on the one hand you want to get started and build the Volocopter on the other hand, one waits for a long time for the results that are actually needed then Of course, to start with the construction, that bites a bit In this respect, that goes beyond several
Optimization steps, that is we just started building as we intuitively imagined and afterwards show the calculations
okay that works fine or there we have to improve a bit Also the “Bild” newspaper had reported about us, she was less interested in the results of the University of Stuttgart but with a bit of local patriotism from the Baden-Württemberg issue, that the Volocopter was calculated at the University of Stuttgart, then you were proud of it My personal hobbyhorse are the electric drives and the motors So I also developed the motors myself with finite element methods simulate the flux density or the losses,
which arise and there also with some iterations developed an engine that is ideal for the Volocopter The motor has a very high power density of about 2.3 kW / kg That is about two and a half times as much as common industrial engines on the scales Our most important partner is the company
DG aircraft construction in Bruchsal You know them from the gliders they have been building for decades There is a lot of experience with plastics processing especially so the production
of CFRP parts So you can see the two here
Half shells for the hull There, the carbon fiber is laminated first separately and afterwards the Shells assembled and still
glued together These are the carrier arms; the rotors are housed on these arms You have six arms in total. So you can see here, the shape was made very precisely on a CNC milling machine So there is also the lower and upper half shell and there, these six arms were then purely laminated by hand We’ve had these computer designs for two years now on the left is a computer animation and then the first time the Volocopter was standing in the meadow that was really a great feeling and it was afterwards when we saw the photos, if we did not stand there now, then we think: Is this also a model or is it a computer animation? The difference is not big The Volocopter has a diameter here
this rotor circle of 7.20 m Of course, the entire rotor surface is a bit larger, a rotor diameter larger That means we are at more than 9 m rotor surface diameter Incidentally, a single rotor has a diameter of 1.80 m So that’s a very nice device Everywhere lightweight construction is announced, that is
very important, every gram counts in aviation much more than the car, because it needs a lot of energy, to bring this weight into the air that is always a tradeoff between: build one sets even more powerful, but then it will be difficult again, then you have to spend more power again or you try to make that as easy as possible from the outset somehow this whole construction process is a search for the optimum So you can see here how the individual arms
be plugged into the hull there you can still see a little,
these are a carbon fiber parts here These connections, of course, everything is calculated that it can withstand the forces This was the first time we introduced this VC200 prototype to the public That was in August 2013, ie nine months ago where we built that in Berlin that’s here in this hall We were nominated for the Green Tech Award 2013 there So the Volocopter floats throughout In the evening of the award ceremony here above the
audience We will be in the category
Aviation did not win the first prize He went to Airbus, but we are still proud to have been there Pretty late, now really in the fall of last year, we came in contact with the company Ascending Technologies They make these drones or camera platforms very professional There are high-quality cameras installed which can also rotate and tilt for professional aerial photography That is, the systems are also very great
mellow The boys have been working on the development for ten years So we were not nearly as far as we would have liked and we have come to agree that we are the controlling system of Ascending
Technologies are used then for our first flights with the VC200 So far, we had a controller similar to the model, just contains a microcontroller if the microcontroller suspends somehow and that is not completely ruled out then nothing works. Then you can not even fly by hand somehow so it is very important that the
Control redundant execute You have several microcontrollers We are still discussing how many we take So 3 times is the minimum Others say, well you can spend every engine a microcontroller and everyone has their own sensors. Then you have 18 completely redundant systems The redundancy is the really important thing about this project is to make sure and that’s what you’re looking at now
does not see this finished prototype yet he sees looks finished
and he flies too but to really make the controls safe enough to sell them that is still a long way to go
So we still have some time to do it The unmanned first flight with the VC200 will be in November 2013 So only about half a year approximately performed in the exhibition hall in Karlsruhe So the exhibition hall was in time, found
currently no fair Thankfully, we were provided for a few days we had ample room to actually do our first tests the hall was high and big enough that you could fly around there properly These flights took place remotely of course you could have sat down there as well We were asked again and again: Yes, why did not you do that? But that was at the time; we have gained so much experience with it with these first tests, that was enough for us to gain insight Of course somebody could have gotten in there as well and could have been flown by pilots remotely through the air But why? So you can see that he is very calm in
the air is lying There are hardly any vibrations here So in that respect our expectations were fully met We are very happy with the flight behavior Because now nobody flew along
is, we also had some more flight time We did about 10 test flights Here you can see, we put a sack of screws in the front, to move the center of gravity slightly forward as you would then in reality Soundwise, sounds a lot different than a helicopter It was quite quiet. In the hall, of course, a very different acoustics than outside but what you can say, it really was
enjoyable with a combustion engine you would have made much more noise there Thank you! Then we were at the AERO, that’s it
Air show in Europe where we have been around for three years each year now somehow and have presented something, this time in the e-flight Expo So it was all electro-planes here, with solar cells partially, conventional aircraft but which were powered by electric motors and the Volocopter was just the eye-catcher there We have also designed a new cockpit by now with new project partners, these glass cockpits are called that, So these flight instruments with integrated that is, everything is displayed there on status information what you need during the flight one has actually no further instruments besides the prescribed devices This makes the cockpit very clear and ultimately easy to use A few words about our financing: So we started the whole thing as a hobby project and started but it quickly became clear we’re going on now and we are
four founders of E-Volo GmbH I’m one of those, so we put private capital in there first in the order of 100,000 euros, in order to push this development for the first time but it soon became clear that more money was needed, if you want to get such a complex development on the line We requested a ZIM project,
So this is a federal funding program where project costs in the order of two million euros were covered In addition, the industrial partners themselves have invested money simply by us propeller, the hull, Provided components without us having to pay them If you put it all together now and the capital we have invested in the project by the end of this year then we end up with about five million euros That’s quite a lot, but considering that one actually A completely new aircraft is Peanuts So if there’s a big company like Airbus had it turned off, there you would have
another one or two hung An interesting way of financing that
So in recent years has gained more and more popularity, is crowdfunding. So we have with the company Seed Match, the largest crowdfunding platform in Germany after this first flight in November
Crowdfunding started, which in turn broke all records, so we were the most successful crowdfunding in Europe until then We have the funding threshold of 100,000 euros that’s sort of, where it ever starts, we have reached after a few minutes and the final threshold of 1.2 million in just under four days usually such a crowdfunding runs 60 days and yes that shows that again
the e-Volo project general approval and recognition and that too
People are willing to put their money in there and they believe in us We are now in a phase where already
a lot to see and something is flying but, as I have already indicated, there is
still a lot to do especially the redundant onboard computer it needs a network, as these on-board computers should also communicate with each other which data you should exchange that’s a lot of software development that is the hardware development
Now, to a very large extent, it has already happened but the software development, that is still a very big chunk that lies ahead also the connection of the flight stick or joystick that has yet to happen, so far ran
that all by remote control On the hardware side has shown, well we can certainly use a bit more power reserve also like batteries with higher energy density always watch what’s left for newer batteries on the market, to easily achieve more flight time So there is a lot of development potential One more word about the fly-by-wire,
That’s true of the big planes it is common practice. An Airbus is just controlled with such wireless joysticks This is an absolute novelty in private aviation that was not conceivable so far that it is so in private aviation
can give something like fly-by-wire that was completely excluded from the
Approval Regulations So there we have introduced a novelty, which has yet to be tested what needs to be discussed, with the appropriate authorities Otherwise: Every gram counts, there is
still saving weight somewhere through improved production methods,
maybe through other materials with a slightly different construction of details you can always get out a few kilograms and that will be done in the near future After that, then have on the aircraft
Stress tests stress tests are made both static and dynamic. That means it really becomes one Flight testing performed where various maneuvers are also carried out For example, it is being tested, what about a fast ascent which climbs can be reached how is the descent and so on and
so on. That’s a lot of work to do there Then the cooperation with the authorities The supreme authority, which is responsible for us
is, is the Federal Ministry of Transport There subordinated the Federal Aviation Authority and finally the ultralight squadrons in the case of the DULV, the German ultralight flight association we all sat around a table and decided in December 2012 Well, we do that, we want to establish these aircraft in Germany that means we have to think up the appropriate regulations for that first there must be something like building codes, how must such an aircraft called Volocopter because at all
which strength values ​​must be adhered to, which speeds may be achieved which surface loads are
present and so on and so forth that has to be worked out
and be fixed in writing The pilot training, that’s an important one
Aspect, because one should be allowed to fly afterwards and of course you have to tell the trainers how things fly and what you pay attention to
must, like the behavior in certain critical situations, that’s all
unlike other aircraft but that too can be done somehow
test and fix in writing the third point is the flight operations code So that means, where do you start and land? My vision of the beginning is: Basically, I want to have something in the garage and I start it directly from my driveway and fly to the mall or business meeting and land there Aber so einfach ist es in Deutschland nicht. Das heißt, im ersten Schritt wird man natürlich Flugplatzzwang haben Da ist dann auch festgelegt, auf welchen Flugplätzen gestartet und gelandet werden darf das alles spielt in diese Flugbetriebsordnung mit rein Auf jeden Fall ist klar, dieses Erprobungsprogramm ist gestartet und es gab ja schon andere Luftfahrzeugklassen im
Ultraleichtflugbereich zuletzt waren das 2003 die Gyrocopter, die auch einen richtigen Boom ausgelöst haben in den letzten zehn Jahren diese haben genau das gleiche Programm durchlaufen und wenn so ein Programm erstmal gestartet ist, dann stehen die Chancen sehr gut, dass das dann auch durchgeführt wird und dass man dann in einigen Jahren, jeder der diese Lizenz erwirbt, damit fliegen darf Ja, unsere Meilensteine… Vom Baubeginn bis zum Erstflug des VC1 verging ungefähr ein halbes Jahr Vom Baubeginn des VC200 bis zum Erstflug war es ein bisschen länger aber auch noch überschaubar, es waren glaube ich 18 Monate, oder so Wir sind jetzt hier an dieser grünen Linie und das sind unsere weiteren Ziele: Die Flugerprobung, die Zulassung und ungefähr so ab 2016 planen wir die Produktion einer Nullserie, also die ersten zehn Stück, die dann an entsprechende Flugschulen erst mal verkauft werden, damit überhaupt die Ausbildung stattfinden kann wie es dann weitergeht, nun ja, wir werden es sehen auf jeden Fall, das ist ein sehr flottes Vorgehen und wir haben hier unten zu sehen diverse Ausstellungen und Auszeichnungen erhalten wenn das so weitergeht, wenn man das
jetzt versucht zu extrapolieren, also E-Volo wird mit Sicherheit auch in den
nächsten Jahren wieder weitere Maßstäbe setzen Erst mal vielen Dank! Ich denke, wir haben jetzt durchaus noch ein bisschen Zeit Ich lasse noch als Zugabe dieses Video laufen Das ist eine Animation, die haben wir relativ am Anfang erstellt Man sieht hier einige der Möglichkeiten, die der Volocopter hat Im Prinzip kann man den in der Luft parken Man kann den irgendwo stehen lassen Man kann damit Rettungseinsätze durchführen Nach erfüllter Mission, kann man den per
Fernsteuerung wieder abrufen dass er zu seiner Position hin, er kommt dann angeflogen Das ist natürlich alles noch Zukunftsmusik Das soll demonstrieren, wenn jetzt mehrere Antriebe ausfallen, dann merkt man das kaum Das System funktioniert auch, wenn einige Antriebe ausgefallen sind Das sind alles ein paar nette Ideen So, und nun bin ich gespannt
auf ihre Fragen Okay, ich hab eine Frage von dem
Vergleich Paragleiter zu Drachenfliegern motiviert und zwar ist es so, wer ohne Training im Drachenflieger versucht loszufliegen, hat eine sehr hohe Chance, beim Erstflug zu sterben Mit einem Gleitschirm ist tatsächlich so, wenn man den Start schafft, wenn man ihn nicht schafft, dann guckt man komisch, weil man in einen Kuhfladen gefallen ist, aber wenn man ihn schafft, man kann so ein Ding mehr oder weniger beim ersten Mal, einfach nur wenn man es sich hat erklären lassen, fliegen. Und Ihr System sieht eigentlich genau so aus als ob eigentlich sozusagen jeder Dieb, der es nie gelernt hat trotzdem glücklich auf und davon fliegen könnte.
Is that so? Das hoffen wir doch! Natürlich, es gehören trotzdem einige
Fähigkeiten dazu und Pilotenkenntnisse das heißt, man muss sich in den Lufträumen auskennen, man muss wissen, wo man fliegen darf und wo man nicht fliegen darf das heißt es sind schon Fähigkeiten
gefordert, die man erstmal erwerben muss Aber rein von der Steuerung her,
denke ich, ist es nicht schwieriger als Autofahren lernen und das lernt man auch
very fast Eine Frage, Sie haben, wie es mir vorkommt, die Bedeutung der mitgeführten
Energie etwas untertrieben oder schwach dargestellt aber für ein fertiges Produkt müssten sie doch eine höhere Energiedichte in den Akkus haben und zwar eine deutlich höhere Gibt es da aus der Industrie, oder der Industrie, mit der Sie Kontakt haben, irgendwelche Timelines? Können die ihnen versprechen, was für
Batterien, was für Akkus in zwei Jahren wenn Sie ihre Nullserie starten, oder in
fünf jahren gibt? Natürlich gibt es eine Menge Versprechungen und es gibt viel Forschung in dem Bereich also wir sind sehr gespannt darauf, was da noch kommt im Moment hat man Labormuster, die durchaus bis zu zehnfacher Energiedichte haben, als die jetzigen Akkus Nur ist es vom Labormuster bis zu einem
serienreifen Produkt natürlich auch noch ein weiter Weg vor allem, was dann die Haltbarkeit angeht, Lebensdauer ja also wir spekulieren einfach darauf,
dass wir in ein paar Jahren wenn der Volocopter wirklich zu kaufen ist,
dass dann die Akkus auch so gut geworden sind, dass es eine interessante Flugzeit ergibt Auf der anderen Seite, die Nicht-Piloten, denken: Ja, was soll man mit 20 Minuten? Die Hubschrauberpiloten sagen 20 Minuten
das reicht vollkommen aus, da kann man doch viel machen, länger fliege ich mit meinem Hubschrauber eh nicht Also auch da gehen die Meinungen auseinander und wir sind mit 20 Minuten schon gar nicht so schlecht Ich habe zwei ganz kurze Fragen: Welchen Preis streben Sie an für
den Volocopter? und die zweite Frage: In Ihrer Animation oder im Video, da war jetzt noch ein zusätzlicher Rotor gezeigt der hinten aufsitzt und für den Vortrieb sorgt, den habe ich jetzt in den Bildern nicht gesehen Dieser zusätzliche Rotor, der ist vor allem dafür gedacht, wenn man hohe Geschwindigkeiten erreichen will normalerweise wird die Geschwindigkeit
dadurch erreicht, dass der Volocopter nach vorne kippt und dann vorwärts fliegt Das heißt für hohe Vorwärtsgeschwindigkeit braucht man hohe Kippwinkel das wollen wir irgendwo limitieren und
dadurch ist auch die Geschwindigkeit begrenzt da kann man also mit einem
zusätzlichen Heckrotor höhere Geschwindigkeiten erreichen Wir wollen das noch testen, aber im Moment hat das keine Priorität Es wurde in diesem Designentwürfen schon mal angedacht, aber im Prototyp erstmal noch nicht realisiert Zum Preis: Gut, das werden wir letztendlich sehen, wenn der in Produktion geht das hängt natürlich auch davon ab, welche Kosten wir dann haben werden und wie das überhaupt vertrieben
shall be und das ist zu früh, da jetzt wirklich endgültige Zahlen zu nennen, aber es wird sicherlich in der ähnlichen Größenordnung liegen, wie andere Ultraleicht-Hubschrauber in dieser Leistungsklasse,
das heißt um 200.000 Euro Es sieht ja so aus, als ob der badische
Teil Baden-Württembergs mal wieder für eine Innovation in Sachen Mobilität sorgen wird Haben sie daran gedacht oder ist daran gedacht, einen autonomen Flugraum zu etablieren, so etwa 200 Meter über Baden-Württemberg mit car-to-go bzw. moovle, wie ja die neue Strategie von Daimler heißt könnte man doch hier den Schwaben zumindest ins “Nachbar-Ausland” Bayern oder eben nach Baden fliegen und wenn es dann abstürzt, dann ist es halt…na wie auch immer Ist sowas angedacht? Weil ich finde so eine autonome Flugeinheit also für Patiententransporte für sehr wichtige Dates interessant. So eine Software müsste man parallel entwickeln die deutsche Flugsicherung hat das sicher auch nochmal ist so etwas denkbar? Aber ich glaube, das
was wir da gesehen haben in diesem Film, das wir ja nie funktionieren, die Dingen crashen ja wahrscheinlich also selbst wenn die Antigravitationsantriebe ante portas stehen die können ja nicht autonom fliegen die Dinger Wir haben das heute morgen nach dem
Vortrag von dem Herrn von Daimler schon überlegt, ist eigentlich einfacher oder schwieriger sowas dreidimensional in der Luft zu machen schwieriger vielleicht insofern, man hat einfach noch eine Dimension mehr eine Raumachse mehr, um die man sich kümmern muss einfacher insofern in der Luft ist
viel weniger los dort oben, da gibt es weniger Hindernisse als auf der Straße, es gibt auch keine Ampeln, die man erkennen muss das heißt, es kann sein, dass es sogar durchaus einfacher ist, solche Assistenzsysteme für Fluggeräte einzuführen aber auch da gelten die gleichen Fragezeichen, die man auch auf der Straße
Has wie sieht es mit der Produkthaftung aus, wie sieht es überhaupt rechtlich aus das ist ein weites Feld also die Ideen sind da, die Technik ist da wir können, dadurch dass wir ohnehin alles Mikrocomputer-gesteuert haben müssen wir gar nicht irgendwelche Aktuatoren einsetzen wir können einfach an unsere Controller andocken und dort halt noch diese Steuerungsebene draufsetzen das ist aber so weites Feld, da wollen wir das also noch nicht vergallopieren,
das ist einfach zu früh das bereits jetzt umzusetzen Ich habe noch eine Frage zur Energiedichte Haben Sie auch über Brennstoffzellen nachgedacht? Brennstoffzellen war auch mal in der
Diskussion, im Prinzip alles, was man so an Möglichkeiten zur Verfügung hat von Hybridantrieben man kann dort sicherlich höhere Flugzeiten erreichen die Frage ist nur, um welchen Preis?
Zum einen gerade mit Brennstoffzellen die Komplexität des Systems wird wesentlich größer die Leistungsdichten von Brennstoffzellen
sind auch nicht so, wie wir das gerne hätten das heißt, wenn wir jetzt eine
Dauerleistung von 50 kW haben wollen dann wiegt die Brennstoffzelle mit allen
Nebenaggregaten also schon wesentlich mehr als das was wir jetzt für den Akku haben Der Wasserstoff selber, der wiegt dann
nicht mehr viel, aber wir haben es durchkalkuliert und sind zu dem Ergebnis gekommen, für diese Anwendung ist die Brennstoffzelle nicht sinnvoll, weil nicht leistungsfähig genug Hybridantrieb mit Verbrennungsmotoren, das ist durchaus eine Variante die wir uns vorstellen können. Da laufen also auch Studien in der Richtung aber meine persönliche Meinung ist, diese ganzen Hybridantriebe, das wird nur eine vorübergehende Erscheinung sein, für die nächsten 15 jahre Irgendwann wird es leistungsfähige Akkus
geben und dann wird man nicht nicht mehr mit Verbrennungsmotoren
rummachen wollen, es macht keinen Sinn mehr dann Tesla zeigt heutzutage schon, dass es geht dass es für Autos machbar ist und wir
haben die Hoffnung, dass wir irgendwann die Akkus zur Verfügung haben
wierden, das wir rein elektrisch fliegen können Ich habe eine Frage zu der Zulassung, bzw. zu der Landebeschränkung auf Flugplätze Sie saßen ja dann mit den entsprechenden Behörden am Tisch und inwieweit gab es da schon Ansätze in die Richtung, dass man auch, sage ich mal auf
großen Privatgeländen oder auch Firmensitzen oder sowas dann landen könnte oder wurde da stark abgeblockt? Es ist klar, man muss erstmal mal anfangen und schauen wie es läuft aber wenn man dann noch mal zehn Jahre in die Zukunft schaut, kann man sich das vorstellen? Naja also erst mal wird man sich an dem orientieren, was für andere Ultraleichtflugzeuge gang und gäbe ist ist die Vorschrift nur auf ausgewiesenen
Flugplätzen starten und landen zu dürfen natürlich sind sich die Behörden auch
darüber im Klaren, dass da auch gerade der Volocopter neue Möglichkeiten
eröffnet, aber damit fängt man auch nicht an darüber diskutiert man dann mal, wenn er wirklich fliegt und wenn man damit Erfahrung gesammelt hat und ich denke, das ist eine Entwicklung, die sich kaum aufhalten lassen wird Wenn wir uns vorstellen die nächsten fünf bis zehn Jahre da wird so ein Volocopter eine Randerscheinung sein, aber irgendwann sagen wir in 30 oder 50 Jahren, da wird sicherlich der Individualverkehr auch in die Luft gegangen sein in einen viel stärkeren Maße, als wir das heute haben Many Thanks!
Jetzt gibt es eine halbstündige Pause und dann geht es weiter mit Cybersecurity und Cyberwar hier in diesem Raum.

  1. I can understand German well enough to follow this talk, but to the publishers of this video I can recommend providing subtitles in English. That would increase the distribution of this video immensely, because a) more people around the world will be able to understand what is being said and b) Google can then index the English text and that will cause this video to be found much more easily.

    (It's a LOT of work though – but for cool videos such as this it's absolutely worth the effort. It can be done with freeware tools, google for "SubtitleCreator".)

  2. Don't really mind the language! but they could have consider to divide this video on different parts and fragment it according to different areas! Even in English is hard to keep attn for such a long time! 

  3. These guys need to look at the regulatory hurdles faced by Dr P Moller who has been building the flying car in US, flight corridors and enforcement yet to be determined or allowed.

  4. You have just one year from now to make it the first vehicle on the sky highway. lol. Actually not terribly difficult with today's technology. It would be much easier to automate electric multicopters than say, robotic cars, which have to contend  with pedestrians, cyclists, cars, buses, trams and trucks. Another good form of transport that was pioneered by Germans (Cabinentaxi) and Americans (Morgantown PRT, still running) in the 1970's is Personal Rapid Transit (PRT). It does not compete with the other modes of transport, takes up little space

  5. Stellt den Volocopter mal dem naechsten James Bond Film zur Verfuegung und dann gehts ab mit der Finanzierung !

  6. Danke für die sehr interessanten einblicke !
    Mein Auto muss noch 5 Jahre halten, dann würde ich einen Volocopter kaufen 🙂

  7. ну поднялся наверх сколько вольт и моторчик понодвится

  8. Immer noch: Ihr hätet damals den ersten Preis verdient!

    Elektroflug ist etwas das ein etablierter Luftfahrtbetrieb nicht so gut kann, wie denn auch.

    Auch Calin Gologan ist dort auf einem besseren Weg, auch wenn ich mir gerade keine Freunde mache..

    Aber Effizienz ist, was in der Luftfahrt die größte Priorität hat.

    Und Effizienz ist vielen Fluggeräten, die teiweise etabliert sind, nicht gegeben.

    Dies wird in der Regel mit höherer Leistung also geringerer Effizienz ausgeglichen.

  9. Ils ne savaient pas que ce n'était pas possible, alors ils l'ont fait….Die wussten nicht dass es nicht möglich ist, dann haben sie's gemacht…
    Bon courage, grüsse aus Frankreich.

  10. This was not a cool video!!!  I have been waiting forever to see this thing fly or at least lift off the ground with a human on board!  I though Germans were more innovative!!!!  Very, Very disappointed! 

  11. hm… schon toll das ganze. aber erstmal ist das mit dem erstflug, von wegen, er reicht ihnen ohne bemannung zu testen bestimmt eher eine frage des gewichtes gewesen. zum anderen rechnen sie für 2 passagiere 150 kilo, was viele kunden die auch mal zu zwei männern fliegen möchten bestimmt in "verlegenheit" bringt.
    dann wären bilder interessant, wo dieses gerät zumindest mal unter freiem himmel startet. in einer halle kann man ja sogar tennisbälle schweben lassen wenn man das will.
    ich bin selbst passioniert aber nicht blind bei solchen ideen.
    ich finde ihre arbeit durchaus bemerkenswert!
    darum verstehen sie mich nicht falsch, ich habe zwar bedenken, bin aber trotzdem beeindruckt von ihrer schöpfung und freue mich auf weitere infos dazu.

  12. Es wird behauptet, dass das "neue Konzept" leise wäre. Ich weiß nicht, wie bei E-Volo "leise" definiert wird aber das Teil ist recht deutlich am Himmel akkustisch zu vernehmen. Wird eure Arbeit bei E Volo eigentlich durch Steuermittel subventioniert?
