Hello dear friends! I welcome all jet thrusters. Starting a small project. I want to upgrade this device and attach here, friends, a combustion chamber. The camera is pretty perfect, that is, everything should work fine. For those who don’t know what it is- I’ll leave a link in the description below the video. In a nutshell I’ll explain This is a centrifugal compressor. There she is – the impeller. Impeller with a diameter of 100 millimeters. I expected that she would give out significant pressure. But the engine can spin this impeller only up to 33,000 rpm. As a result, the pressure here is at the outlet no more than 0.2 atmospheres. While a donor is being sought to install this unit in the car and so as not to be bored, I decided a little upgrade this unit. I decided to attach a combustion chamber with a viewing window here and you can see how the combustion of fuel takes place inside. At the dawn of aviation, such engines were already made, True they powered not from the electric motor, but from the internal combustion engine. But the principle was the same. ICE twisted the compressor impeller, and then a combustion chamber was installed. It all worked successfully gave out traction. But such a thing did not take root, because it was not practical. We need fuel for both the combustion chamber and the internal combustion engine, and it didn’t give out such a craving overly fantastic so that it can be used successfully. In general, friends, let’s start! We begin to manufacture. We put off this drawing, because there is already another. Here are 2 main reamers of flame tubes. All diameters are already calculated, everything is counted. You can start manufacturing. I have a couple piece of iron with stainless steel. With them we will sculpt this whole thing. Oh yes, I forgot, I must shy away coffee (drink). Now, let’s start. To begin, dissolve this stainless steel and we will level it. I will use the rollers to level the metal. That’s already more or less smoothly. I turned two of these pieces of iron in size. Also here, as you can see, I welding took a piece. Because not enough, friends. that is, in this video I I don’t translate material, but vice versa. I’m making from pieces, from some rubbish. She cringed even more Here I cover with my finger, because here I burned. I do not want to show. In the end, everything will be fine. She will be full of holes. Now I will be full of holes. To do this, cut the drawing. The drawing also serves us pattern for making holes. That’s how it all turns out. It’s good when there is such a thing in the household. Thanks to one good man! Now to poke (make a hole with a core) is just a fairy tale, guys. So once and drove … Here’s what happened. The entire substrate is scratched. Also, the whole point has become. now we tear off the paper. We don’t need her now. Neatly, suddenly a successful combustion chamber will be. You can repeat it again sometime already in turbojet engine (turbojet engine). Fire tube made of stainless steel 0.5 mm thick. Cooking it by welding is problematic. One millimeter I easily cook in a tig-welding. But half a millimeter is hard. it turns out. But I adapted in one interesting way. Here you can drill. Here you can see that the density of the holes is higher. This is the inside. Here the density is less but the area of all holes is the same: what is here, what is here. The air must penetrate from all sides evenly, then it will be good. Such guys turned out crooked pieces of iron. Glands with multiple holes. Here their unreal amount. Especially in this row. Now I’m deburring here below and we roll again on makeshift rollers. See how it aligns? Very well. Once and done. These are two. Bend into the rings. It turned out 2 nice details. These are parts of a flame tube, an annular combustion chamber. This is a seam, guys. This seam after tig welding. It didn’t work out badly here either, guys. Not bad at all. Mastery is growing. Here is how. Here it is. It will be a nozzle exhaust outlet. Everything will look that way and no other way. There is a process. Here, I did not succeed a little. Led this detail here. I think everything will be welded and everything will be fine. Now I am engaged in evaporation tubes. There are additional holes here. They will now be welded here. Evaporating tubes are needed to evaporate fuel, if I use kerosene as a fuel for combustion. It’s already becoming interesting what will come of it all. The finish is near. Although there is still a lot of work. I hope everyone will work fine. Made a big exit. Most likely it will have to be reduced. In general, not a problem. The main thing is to start, start and collect everything. Still make a viewing window. This is how the combustion chamber looks from the inside. These are evaporation tubes. There are 11 of them. I have all the details made of stainless steel. Pressed the ring. The ring will still need to be picked up later by welding. Well, we continue. It remains to make the case. Well, here to make a stub. I remembered that I have a lot of such stainless steel. This is a heat resistant stainless steel and make the combustion chamber very difficult. You can’t drill it with a small drill. But here on the case – will go. Because it is cooked by welding well. Beautiful! That’s how my rolls bend guys. You can pay attention that even at the entrance everything rounded turns out. That is, there is no such approach ridiculous … This will be the case. The front side. I’ll try to do high quality seam. The fit is just precision, friends. Everything converges, there are no gaps. We try. I’ve been using it all this time such transparent nozzles with gas lens. The mask is very visible arc. Degrease with alcohol. You can say guys that the seam turned out. Of course a large seam, could have been done a little less. But such a technology welding of thin metals with me. I can’t lead in one line, and so welded by welding, I need to do just that. And so I can confidently brew – dots. Points at a certain distance about a millimeter from the line and try to keep the line exactly. The finishing touches are already underway. I weld the cap. There she is, beauty. Things are going well. I light the arc from below, lift up. Because the bottom is a thick piece, and on top is thin. Done, the sealing took place. Here is what our detail looks like. It remains to make a power system, supply of tubes and it will be possible test! Inside the evaporator tubes are welded. Here are the inputs. It shows that there are small holes for cooling the nozzle. Here is such a system. I don’t know if this device will work? But one thing is for sure that I was good at tig welding. Because you need to learn constantly and always and to everything. I’m already doing better than for the first time. And much better. Of course, it’s clumsy in some places, but this must be taken into account. Metal leads very strongly to the side. It leads very much. So we look at what we get. This is inserted here. In general, the detail turned out even to be airplane. Somehow it’s not heavy … Generally light. Here is the nozzle guys. This is how it looks. Well, that’s how it connects. So the combustion chamber completely ready! Connected batteries, regulator and you can even test a little bit. What will it show? Pressure gauge will measure pressure after the compressor and before the flame tube. That is, it will give us some understanding, how it will work. We look. Great guys, it turns out. Before the flame tube pressure is created – it is very good. When the mixture ignites, it will also appear in the flame tube back pressure and this is the pressure in theory it should rise to 0.02. That is, it will be fully used the full potential of this compressed air. That’s all for me! To whom it was interesting – subscribe to the channel, support like. Thank you all for your attention and all for now! Soon we will see what this unit is capable of and what can he give out.
