- I was wondering if anybody has tried to make a small
- turbojet engine out of a car (or, more likely, truck)
- turbocharger. It seems to me that the hard part of
- a turbojet is the compressor and turbine, and those
- are already being produced in large quantities for the
- auto market. The burner (combustion chamber) and
- fuel injection system seem relatively simple in comparison.
-
- I would think that a turbo for a big (20 liter) truck would
- generate about 130 nt or about 30 pounds of thrust. Not
- enough to push my 172, but an interesting amount for
- some purposes.
-
- 20 liters @ 3000 rpm * .5 cycles/revolution => .5 meter^3/sec
- say 200 m/sec exhaust velocity and 1.3 kg/meter^3
- .5 * 200 * 1.3 => 130 nt or 29.21 lbs.
