This is beginning to look more promising! I'm looking forward to seeing the next test run.

Very nice work! Keep em' comming!

Geil Jungs, viel Erfolg dabei. Für meine muss ich erst mal ein Verdichterdeckel drehen und die Einspritzanlage löten. ;)

you guys are awesome, really nice work. wish i could do this but i don't have time or money :( maybe when summer comes

Right at the diffuser, where the turn is, the exit area of the diffuser is not small enough. The blades on your diffuser need to be shorter, or the hub that they are machined on needs to be bigger, to close the gaps. It's all in your diffuser. Can you calculate the total inlet area, and compare to your diffuser outlet area? the difference between the inlet area to your diffuser area determines your compression ratio. It should be the same as the area of the outlet at the compressor. This will retain your compression. The depth of the compressor blades at the tips needs to be measured around the whole circle, and the diffuser area needs to match. When it does, the fins on the diffuser will be very short. This is what you want.
Additionally, the back side of your diffuser plate needs to cover over the area where your fuel/oil plumbing enters. On your engine, the compressor would have to keep the air behind the diffuser compressed in that area to maintain compression. This air would create turbulence to your flow, and cause problems.
I'll have to find a way to send you a picture of what I mean, and see if it helps.

Sieht ja sehr vielversprechend aus!;) Freu mich auf die testläufe! Hoffentlich habt ihr genauso viel Glück wie ich mit meinem U-Boot projekt, hab grad heute die Testfahrt gemacht, die keine Testfahrt war, sondern eine richtige Fahrt!;) Ziel erreicht

so, to really get compression, the stator behind your very nice compressor wheel needs to be right up against the compressor, with a small space for no friction, and the diffuser needs to be tighter to keep the compression. There are a lot of little minor problems with this engine, but you are so close.
Good luck.

ich finde dieses projekt echt cool nur möchte ich kurz anmerken dass es meiner meinung nach nicht sehr klug war bei 1:06 das werkstück anzulegen während der bohrer schon am arbeiten war, da das bohrloch dadurch ungenau werden kann und das bei einer turbine nicht wünschenswert ist

[SEHRD]

It would be great for schools to get involved. perhaps design a blisk and have us machine it.

[arcadegamesify]

what's the compression ratio on this? it might run better if it's higher

[hosenansari]

you are making all this engine .but my question is that does it

[Vule_]

Wait, you made the ebay page where we can buy every single item to build the engine :O???

[seansoblixe]

i hae yet to see a sucsesfull test sellf sustaining run

[sebastian]

Where's the self sustaining test 😂
