Also there have been motors of that type around for eons. The ones I've seen are pneumatic.
Rotary vane motors are what they put in pneumatic impact wrenches.
They also make rotary vane compressors.
What I want to try is, put a rotary vane compressor on a common shaft with a rotary vane motor.
the compressor feeds a firebox where kerosene in atomized and burned.
The firebox exhausts into the motor.
The compressor to motor ratio would have to be 1:>1
(Haven’t done the math, but 1:2 might be a starting point)
Basically a gas turbine, except instead of turbines, rotary vane compressor/motor.
I don’t have a drawing, but can you imagine that?
