Just a little PSA, if the turbine or a compressor stage explodes, it will send a lot of very fast shrapnel in all directions perpendicular to the main axis. Please don't have people sitting in the death zone.
Other people's hobbies: gardening, photography, jogging. The german: Building a fucking jet engine at home haha. Really cool, happy to have found this. Also his neighbors must love him.
Hi guys, Thanks for watching and asking. The engine runs very well, but I am still missing some thrust. If you want to see the first job for the engine, please click the link😊 ruclips.net/video/YgQemBYqgO4/видео.html Andy
good job wonderfull machine respect and well made. cooling is important especialy the bearings. i had the same problem with cooling and lubrication to the bearings it sounds that the turbine touches the NGV system axiale. i think maybe 2 mm more clearance will solve it.
So i am a bit of a curious man, and i wonder if one could have the fins mounted from a rail on the housing that spins inward with no central shaft or secondary purpose for a shaft such as to move the air around it in a configuration to cause the bottle neck at a rocket expansion cone just after the fuel is mixed, so that when the air fuel mixture exits the choke point the compression of the air is great enough for it to combust the fuel in the cone for maximum thrust... secondary air stream around the outer circumference of the rocket cone to create force vectoring?
This is working really well, that NGV made a difference. please don't allow anyone to stand in line of the rotational axis of the turbine wheel when it's running, when they let go the parts fly out sideways especially with no nozzle on. I've seen it/had it happen a few times
Hi, I know the hazard areas around jet engines. So far all went well and the max rpm (70 000) is far away. Do you own some jet engines from Phill, or did you record the videos during a testrun? I like the axial comp sound👍👍👍 At the moment I am building a bigger housing and diffuser section. Still looking for thrust😁 Andy
@@Praendy Hi Andy, the axial engine and the Barjay replica are Phills although I do have a couple of his engines which are smaller. I used to help Phill at this workshop when he was making the Wasp engines and others and sometime about 6 years ago we met up so I could film the axial and Barjay replica. Look forward to seeing more runs and improvements Paul
Hi! I am really impressed with your work and taking this on as my FYP in Mechanical engineering. I will need some help doing the cost analysis and procurement of parts. Would be really helpful if I can get in contact with you.
Hi, Ich habe eine Wuchtmaschine ergattert und darüber auch ein Video gemacht. Vorher habe ich mit der Hand gewuchtet, was bei 2,5 Kg Rotorgewicht schwierig war. Mfg Andy ruclips.net/video/KMf3Z1_QVF0/видео.htmlfeature=shared
Hydro turbines introduced so funny names, but I understand that axial compressor blades mostly lie in a plane ( small angle ) to press into the chamber. Turbine blades on the other hand are "vertical" at angle 90° for maximum torque. So I understood that the exhaust velocity is far above the velocity of the blades? So it seems like that we could just place counter rotating n1, n2, and n3 ( co to n1 ) turbines in series. With guide vanes before and after this stack.
Hi John, The engine casinh in the back is not very hot in idle. ~150-200°C The exhaust temperature is much hotter 500-700°C. So it is possible to touch the engine a short time, to feel any vibrations. Andy
I use ngv and turbine inconel 713c. Haven't tried the 316 or 310s, so I'm not sure if they can handle the heat. The temperature of the exhaust nozzle can reach 900 degrees, so there is no problem using 316.
Seems like it runs pretty good once started. Might need to figure a way to keep it spinning on cool-down so you don't get any warping or other similar issues. My limited understanding is stopping a jet turbine while it's still hot may lead to bad news regarding its maintenance. And is the scraping at the end on the outer periphery or is it the bearings?
Hi, the ngv is not the problem. I figured out the engine housing, where the ngv is screwed in, is a bit warped. At the moment I build a new "bigger" housing and the problem will be solved. Usualy I use a 90mm electric impeller in front of the air intake to cool down the engine. Thank you😉 Andy
I know of several companies that make small jet engines in Europe. Could you possibly buy fuel pumps for jet engines with a thrust of 100 kg or more? For example the fuel pump of jet cat p1000 or pbs tj 100 and tj150. I'm looking for a fuel pump with 3lpm performance at 6bar. They don't answer my emails. can you do my favor? If I can't buy a pump, I'll have to make the pump myself. Pump development is difficult because there is no company that makes a small amount of small gears or the like.
1:43 it should be opposite, blades facing the hole inwards, and an outer mounting system with ball bearings, like a tank turret ring. Then, the turbine can be made any length.... creates a fire tornado, which is great, also quieter.
Another way of increasing efficiency in a somatic way (same thing, slightly different variation), is changing the type of air intake, and the type of nozzle. At that point, you want it to run as effectively as possible, on the lowest quality fuels, so it can always go up a fuel grade and work even better.
Hi Steven, English subtitles should be available. Can you get a 2nd stage turbine wheel from a Tornado APU? Then I can send you some specs and measurements. If you dont have the same wheels, a material list is useless. Andy

what is the most efficent blade angle for n1 n2 and n3 shaft for turbojet engines (totaly not for backyard f16c viper)
???

Before shut down its necessary run up in idle to equalize temperature to avoid damage.
I could not read the scale, what was te thrust?
@@comedicsketches Cool and thanks
