use a turbo charger and fuel injection system from a car...
it can be done that way
place a pipe between the intake and exhaust sides of the pump..
the pipe must be taped so you can screw in injectors and glow or spark plugs
start it spinning with compressed air add fuel and spark or glow plug heat
and it should run
p.s.
myth busters couldn't change a tire..
if the instructions weren't on the jack

Over the years Popular Science had some ads in the back pages on how to build your own helicopter. The power source for this design was a ram jet.
Ram jets have no moving parts and a very simple one can be made using differeent sizes of pipe nested together.
Bacically you fabricate a venturi (ejector) inside of a larger venturi. Air and fuel (propane) are drawn into the smaller venturi wher it is mixed then burned at its outlet. (kind of like a bunsen burner) The combustion products are directed into the inlet of the second larger venturi where additional air is drawn in .
The thrust to weight ratio is horrid without forward motion to drive air into the inlet but you can develop thrust without a rotating compressor.

The mythbusters jet engine actually worked!!
The one they did from vacuum cleaner parts.
I should warn you that, it is very dangerous sice highly combustible fuel is used!!
