hand cut turbine

this is my hand ground 84 mm dia turbine cut from inconel 718 has no see through between blades as it is a power turbine for direct coupling via gearing and clutch for my turbo prop the numbers painted on the hub are for my strob balancer i made it helps narrow down where the imbalance is.

Are those Reaction type blades?

[8040john]

@sgtpepperoni  yes they are reaction type blades you can allways tell because the gap between the inlet to two blades is always larger than the gap between the outlet.

[8040john]

the inconel originally came from a local scrap yard many years ago have not seen any usefull pieces since.

as to suitability as long as you keep the exhaust temperature bellow 640 degrees C

it is quite suitable, inconel 713 is stronger once you exceed these temperatures but i have never found it available in bar stock only references seem to be to do with casting it. hope this helps.

thanks very much could still be better i will probably do another at some point its ironic though ive got all these skills and i still cant get a job .

oh well thats life for you!!

@8040john if you can't get a job, then that sure is scary for me, because I have no such skills hehe

[8040john]

@EasternMerchant tell me about it mind you i have just got a job working in an engineering company in the quality control department its a minimum wage job at the moment as i am not qualified so will have to learn as i go along its very complex work and very high specification as its all aerospace stuff so the tolerances are extremly tight .

if you use it in a jet engine it will shake itself apart

i still don't get it how do you cut those pales , can u post a video when you cut them ?

Once again this is quite useless because blades will disintegrate at high speed.

correct construction is to make blades thick at the base and thinner at endings.

also it was bad idea to remove that much on center material because it need to hold blades and has to sustain enormous forces.

I think that's a beautiful piece of work. I'll subscribe and I want to see the rest.

Thanks.

Great Job. there is a market ofr solar thermal power generation . houe hold scale if you could ever manage to do this practiacle and comercial.

keep  the great work
