10 Unusual Aircraft | Smallest Manned Twin-Engine | Hydrogen Fuel Cell Powered Plane

November 17, 2019


– [Glen] Aircraft have been around since the Wright brothers first flew at Kitty Hawk and people have been designing new ones ever since. Some flight low. Some fly high. And some don’t end up flying at all. I’m Glen and today we’re bringing you 10 unusual aircraft that
either made it or didn’t. (upbeat music) – [Narrator] Number 10. – [Glen] Initially conceived in 1982 by Charles Ligeti of Australia, the joined wing all-composite ducted fan Ligeti Stratos was the first full-sized Stratus prototype built between 1984 and 1985 when Charles Ligeti made his first 45-minute test flight in April. The empty aircraft weighs 172 pounds which is light enough to
qualify as an ultralight in the United States. The company was said
to produce 20 aircraft in the spring of 1987, but during a short test flight of a highly-modified
production version late in 1987 the airplane stalled during landing and Charles Ligeti was killed, causing the venture to
end a few months later. (upbeat music) – [Narrator] Number 9. – [Glen] Rutan’s best-selling
design, the Long-EZ is a stretched-out version of the VariEze. The signature design element, the forward Airfoil, helps efficiency and improves
stall characteristics. Meant to be easy to build the Long-EZ was almost completely customizable and came with a Lycoming
135 horsepower engine. Because of different customizations these have some advantages and have set records
for distance and speed. These have a wingspan of 26 feet, an empty weight of 710 pounds, a cruising speed of 144 miles per hour, a top speed of 185 miles per hour and a range of just over 2,000 miles. Around 12,000 plans for the EZs sold and due to customizations, cost and performance vary. (upbeat music) – [Narrator] Number eight. – [Glen] The ill-fated
Pond Racer Rutan model 158 built by scaled composites
and funded by Bob Pond, a wax magnate, was just ahead of engine technology and ran on a pair of 300ZX VG30 engines that required preheating of coolants and all the oils. The approach speed at landing was the same as an airliner at 140 knots and it didn’t have flaps to slow it, making it extremely difficult to land. Designed to be the cleanest
prompt driven plane in history the choice of engine was the primary cause of its demise. They never made more than 600 horsepower and it had undetermined
oiling problems due to the constant RPM it was running. In 1993 it caught fire and threw a rod, landing away from the airport and killing the pilot, ending an excellent idea for an airplane with lousy planning. (upbeat music) – [Narrator] Number 7. – [Glen] Aron Flying Ship Ltd. specializes in manufacturing and
developing WIG aircraft. WIG craft fly utilizing the WIG effect which is the aerodynamic change that happens when an object flies just above the surface of the water. The M80 can carry a pilot, copilot and a crew of six, comes with a 750 horsepower
turboprop engine, has a cruising speed of
about 100 miles per hour, a top speed of 125 miles per hour and a maximum weight of a
little over 6,800 pounds. Landing and taking off can be done in up to six foot waves. This has a top speed of
54 knots in ship mode and this flies at an
altitude of almost 500 feet. (upbeat music) – [Narrator] Number 6. – [Glen] A composite
construction microlight, The Snark is the creation of W. B. Barber. Barber completed four different models before coming up with the
fifth model, the HA3B. Constructed from Kevlar and carbon fiber the propeller powered aircraft features elevated tandem seating in front of a shoulder-mounted wing. The engine cruises at 128 miles per hour with the three-blade sport prop propeller and has a range of 650 miles, a top speed of 140 miles per hour, but it may go faster. (upbeat music) [Narrator] Number 5. Designed by Northrop Grumman, the Firebird, an
intelligence-gathering aircraft was one of the last aircraft designed by Burt Rutan. First flown in 2010, the Firebird has autonomous or optional piloted models. Powered by a Lycoming TEO
540 flat six piston engine this has a maximum takeoff
weight of 5,000 pounds and is designed to fly up to 40 hours at a top speed of 230 miles per hour at an altitude of 30,000 feet, and has hardpoints to carry weapons. Though currently it’s unarmed. (upbeat music) – [Narrator] Number 4. – [Glen] Intended for instructional and training flights the
Elitar Sigma Aircraft is designed to conform with the United States FAA regulations for light sport plane. The airplane is a high-wing monoplane with a front top-mounted power plant and conventional tail design. The Sigma comes with
a Rotax 912 ULS engine and has a wingspan of 32 feet, a length of 20 feet and a maximum speed of 130 knots, with a range of 404 miles. (upbeat music) – [Narrator] Number 3. – [Glen] Trying to get into the light airplane market in 1974 Burt Raynes produced the Rohr 2175. Originally the 71 X, a low wing Delta made of stressed skin, fiber reinforced plastic construction and propelled by a Lycoming
150 horsepower engine that gave this a top speed
of 175 miles per hour. The landing gear is fixed and rigid. The vertical tail is attached to the top of the propeller shroud
and it is difficult to find a single predictable feature in the aircraft. Due to financial trouble
with other projects this project ended with only one prototype having spent time in the air. (upbeat music) – [Narrator] Number 2. – [Glen] The Colomban Cri Cri prototype was flown for the first time by Robert Wasan in 1973. Designed for experimental
aircraft builders this plane was built only according to the plans distributed by its designer. Made from aluminum sheet
glued to Klegecell Foam the aircraft is the
smallest twin-engine plane in the world, has a 16 foot wingspan and
weighs just 185 pounds. Equipped initially with two
turbo jet piston engines of 15 horsepower each
this cantilever low wing featured fixed tricycle landing gear and a single seat enclosed cockpit. In 2010 the Green Cri Cri, using two electric motors, each producing 25 horsepower, and only 75% of its power
broke the speed record for electric aircraft by traveling at 162 miles per hour. If it wasn’t for the
stress on the airframe, according to the engineering firm, it could have gone at speeds of 220 miles per hour. (upbeat music) – [Narrator] Number 1. – [Glen] A collaboration between aircraft manufacturer, Pipistrel, the University of Ulm, fuel-cell specialists Hydrogenics and the German Aerospace Center Institute of engineering
and Thermodynamics, the HY4 Aircraft took off on its first initial flight from Stuttgart Airport in Germany in 2016. The aircraft powered by a hybrid fuel cell and battery system is the world’s first four-seater passenger
aircraft powered solely by electric propulsion and a hydrogen fuel cell system. Flight with the HY4 is
environmentally friendly, silent, is safer and has a better range than its predecessors. With an estimated range
of 1,500 kilometers the plane runs on fuel cells that makes a supply of hydrogen and oxygen to trigger a controlled explosion, generating an electrical current to power the motor and
drive the propeller. – This episode of Minds Eye Design is brought to you by the Autolover A8. This windshield Heads Up

  1. Eso aviones pekeños te acaban..eso era lo k sentía cuando aprendía avolar en un ultra ligero uno ni bien cabe en esos aviones

  2. #7 is the most no the best designed aircraft it can do land and sea plus cruze at five hundred feet above water that's my only favorite plane out of the group 😆😆👍👍

  3. A crew of six? Another video made by the we don’t know a thing about what we’re talking about people. Probably the same people who made the new Star Trek std.

  4. Nice video guys I didn't know of most of these and good luck getting me into any of them lol. I did love number two though it is soooo tiny lol.

  5. Electric anything isn't exactly green and hydrogen is not efficient when it takes twice the energy to make it. It's not just the end result that matters, it's what is done along the way.

  6. I am not an aeronautical engineer, but if the landing kills the pilot I don't call it a landing, I call it a crash. Maybe it's just me.

  7. You forgot one big failure. Bee Dee 5. The FAA never approved an engine for the aircraft and it looked a lot more sounder built then some of these.

  8. With the Colomban Cri-Cri I think you need to do more research… The plane first flew with 2 10 hp two cycle piston engines. The design was up-rated twice. I have plans for the Cri-Cri aircraft and NO WHERE do I find anything on a piston turbo jet engine. The ones fitted with turbo jet engines is something a builder decided to do, not how Michel Colomban designed the aircraft.

  9. "10 Unusual aircraft that either made it or didn't"
    Well that narrows it down…
    to every single one of them ever made.

  10. I kind of wanted more background info on the aircraft. For example I discovered the Long-EZ when reading about the singer John Denver's death in 1997. It wasn't a bad design – he died because the fuel cock had been badly sited behind his shoulder by a kit builder – but its futuristic concept masked the fact that it needed a very long runway for t/o and landing. Not ideal in a light plane. Other snippets like that would have added some flesh to the vid's bones. Thanks anyway!

  11. God that german translations are horrible, i didnt even understand the title just leave it on english we learn english in school

  12. Fuel cell that makes a controlled explosion to create electricity? Opps, someone didn't do their home work. Hydrogen fuel cells create electricity directly from the Hydrogen.

  13. If you’re going to put out an informative video, you need to get your facts straight and learn how to pronounce the important names. Don’t be “fake” news.

  14. Join EAA…….. I was a member for years. Went to the events…… Got the magazines in my mail….. Never built one but learned a lot.

  15. Cassy(you are an awesome looking lady) please marry me I'm calling the cops because you have stolen my heart 😎❤💓💍

  16. Could you guys do a special on fixed wing aircraft of the Viet Nam War era the Mohawk the Bronco the cessna observer plane among others..as an example thank you!!

  17. Every now and then I see Mike Melville's Rutan LongEZ flying by. It's pretty neat that the information age allows me to know that plane that is flying past me.

  18. #4 would look a lot better, a bit more quiet if the HIGH revving Rotax were placed aft of the fuselage…imho.

  19. Nope, the (f) lyer is the biggest lie ever. A german expand in the US, Gustav Weisskopf was the first man flying, in 1899 – few jumps and 1901 long time flying, in New York. The wrights were his helpers and stole the idea, well helped by WW1 which demonised any germans, and therefore pushed forward the americans instead. Not the first time such a thing happened, and surely not the last…
