Nice build ,not the easiest combustor to get running right.take a couple of degrees off the turbine wheel angle at the tips should reduce the flames and heat it will make the combuster work better increase the case pressure. Can't see your 3 springs( number 24) on the back side of the diffuser to keep the combustor pushed back and sealed on outer case. good video showing all the parts.
@@QuizWave594 never needed the vaporiser coil I made the updated combustor that uses 8 injector needles and 8 hockey stick shaped tubes on the front wall of combustor .runs a lot more even no steam train sound and no need to add petrol into the fuel.the hockey stick shaped tubes use 6mm o/d 5mm i/d or 1/4 o/d works ok. you can salvage heat resistant tube from old electric cooker elements.
@@QuizWave594 No the minimum you need is stainless steel 316 I think oven elements might be some form of inconel which is better, when the engine is running you can seen right into the combuster the tubes glow orange to yellow .
@@reedy93 . Actually I can't find exact pipe it's struggle to find exactly 😩😭. I have 300mm stainless steel pipe with 8mm o/d and 0.2 thickness which might be good but book say 1300mm long pipe. Can i use hockey stick system with rest same design? Or I should weld 4 stainless steel pipe which is 300mm . 300×4= 1200mm but still 100mm short but i think it won't effect the performance. But it's 8mm o/d and in fd3 design used 5mm. please help sir.???
So how much thrust do you think your gas turbine is generating?By the way it looks very perfect.

Where you get vaporiser pipe? it's hard to find exact pipe with 5mm and 0.3 thickness.

@@reedy93 . Can i use copper pipe instead of stainless steel? 🤔 what is your opinion? Will it work?

Very nice vintage staff.
can you please provide a step by step build guide for this engine?
your the genius

Yes i know i ordered it from germany
