Direct drive turbine engine

[sven]

Hi,

I got too good offer for small direct shaft drive turbine and before buy it, Id like to get some advice. Its Pirna gt027-1. Its rated 100kw shaft output
Turbine needs bit of work,but it is in working order, Im conserned is it possible to connect its direct(reduced)shaft output somehow to the wheels, any ideas? Or maybe use its thrust output and build afterburber?

Cheers,

Sven

Hi Sven

Single shaft engines are great for generators , but not good for "road vehicle" due to there very poor power/torque curves , theres very little power below 50% rpm, at which point the engine might be producing ~10% of its potential power and ~30% of its max torque , you'd need some sort of high stall "torque converter" and/or multi speed gearbox to get the best out of the engine .

As for using it as a thrust engine , again not a great idea as the turbine wheel and NGV are designed for power production , not thrust .

You'd have a better outcome going to the trouble of setting up the required transmission and getting those 100Kw of power to the ground rather than try and produce thrust which would be < 100 kg even with afterburn .

Thanks John for advice, I appreciate it.

Hi Sven,

In terms of setting up a transmission an option my be to get an electric generator on the shaft output, possibly using some kind of step down gearbox to get the speed in a range we like, then using electric motors to get the power to wheels.

That way you'd be able to use electronics rather than a multi speed gearbox.

Just an idea I've had and want to see done, as soon as I've cleared a few other projects off my list I'll have a crack at myself.

Cheers,
