Small turbine build

[jack]

Hello to everyone, i would like to share some pics of my turbine build. It's more like a pilot build just to get the feeling of building a turbine ( and because i'm still collecting parts for the bigger one). It took me about one week sofar. It's not perfectly made, but all parts, except the turbine and compressor wheel are homemade on a simple milling machine.
More pics will follow soon.

I will, and i would like to say that this is a great forum with lot's of information.
And some awesome builds also, (witch make this little turbine look like peanuts).

Top job Jack, Look forward to seeing a video on the first run.

Just remember size isn't everything.... (or that what I tell my wife )

Here is a video of a previous build from 2 years ago.
It was a pretty primitive build but it did run ok.

Here are some new pics with the complete combustion chamber finaly finished and in place.
It was a interesting job getting those 1.5 mm holes drilled in stainless sheet metal.










The only things left to do are making the NGV inner ring, the injector ring and outer casing.

That is some lovely work there. Did you even do the intake trumpet on the mill?

Thanks for sharing the video as well, it really sounded like it was going for it at the end

Are you working to plans or have you designed the whole thing yourself?

[jack]

Thank you, and yes the trumpet was also done on the mill. It was done with a hand rotary table, witch after turning it by hand for half an hour i hooked it up to an DC motor and let him take care of that.
And for the design of the engine i have some plans of a GR180 and a MW54, but they are more like a ( very usefull ) guide to work with.
These engine's, especialy the GR180, are much bigger then the one i'm building, witch does' n matter because the basics are all the same, except for the turbine wheels. They use axial wheels insted of the radial i'm using
