LPS 130 Turboprop / Powershaft

Huraa! The turbine is running again! Fast acceleration and that at warmer and colder days! Enlarged the holes in the rear. Will going to enlarge them even more...
Moved the Inlet evenn more away! (1.5mm!!!!!!!!!). It's running on 90k RPM with only 370°. Fabulous!

I don't think a 1.5mm gap is working when you put a load on it..... strange that you get the low egt reading.

 

Can anyone give me the drawing on how to build a turboprop 2 stage gearbox. Please email me at.keron_mcpherson@hotmail.com. I will really like to make one of these for my helicopter

 

Sorry there are no blueprints for a 2 stage gearbox! Please read the book of kurt schreckling "turboprop engine"
Regards

 

Hey Guys
Will show you the first coupling of my second stage

 

Ok cool. I have a kj66 turbine engine and I want to use a 70mm turbine wheel as the second stage. Would you think that would work. Am not planning on using gas turbine wheel. Just normal turbine wheel

 

What you think. It's to work on my helicopter

 

Sorry that will not work! read through the Internet....there are a lot of people who have tried that. At least you need a wheel with a diameter of min. 85mm

 

Ok. Where can I buy one of those 85mm wheel ? And what other parts needed to make the 2 stage gearbox. I tried to find a link but never saw anything on how to make it
