Hello everyone!
Thought I would share my first DIY turbine project in the works. The goal is to drive a small 12v 30amp alternator via free power section for general use. The gas producer section is complete and was based on a T3 variant turbocharge and automotive accessories. The unit is semi-self starting via two metered fuel orifices (start and run), impingement air and a P3 pneumatic fuel governor valve.
Will update as the project gets moving again!

Hi
What an interesting arrangement of bits and pieces , well done :-)
You shouldn't have any problems driving your generator .
I'm a tad concerned about the length of your combustor though if you start going to higher power settings , what sort of flametube and fueling is it using ??
Cheers
John

Hi John, Unfortunately I have the same worries.. As much as I kicked myself for not calculating the appropriate size, I ended up building a "trial and error can" as a experiment to see how compact I could go. The can measures approximately 100mmx50mm and operates on LPG. The fuel nozzle is a pipe cap welded into the top flange with four 90 degree 3mm holes. Dilution holes were essentially 150% of the compressor diameter and the bypass area is unknown.   |

Hi Dustin
OH !!!! , that is a tad small :-(........... thankfully the LPG is very forgiving for both air/fuel ratio and burning speed , ........you would be having problems on kero .
Cheers
John

Very nice! You've made startup look all too easy. Can you tell me more about your p3 fuel control please, how have you set that up?

Hey aus, The governor is made from the turbos existing waste gate actuator and a small ball valve. Fuel is restricted by the waste gate actuator shutting the ball valve once P3 reaches 14psi. The engine has been updated with a acceleration control that utilizes a lower pressure waste gate in a similar setup.   |

What a "Brilliant" idea for a governor..!!
Well done Sir.
