Some of you may recognise this engine if you have visited my friend Adrian Bennett’s website (www.jetpower.co.uk). We did a three way swap with Jon Starr and I ended up with the Tiernay after parting company with the Nimbus.
The Tiernay TT10 is a small gas turbine engine from a US Airforce ground power unit. It was originally designed to supply 24v at 10kw of power in order to power aircraft on the ground. The max horsepower is somewhere in the region of 150 HP. The little engine is quite neat and has come with everything to start it except the fuel pump and engine control unit (ECU). It’s in really good condition and as I have the generator I hope to restore it back to it’s original function as a DC generator. You never know when you may need a 24v, 300 Amp supply!
Here’s a few more pic’s:

Here’s the turbine with the thermocouple probe:
The first job is to add some more metal work to Adrian’s frame so that we can mount a fuel pump and the other ancillaries including a control panel. I plan to build up a small control box as a temporary unit while I figure out the best system for the fuel delivery and control. I would like to build up an electronic engine control unit although this may be quite a complicated and tall order. Here’s the frame all painted up:
