Couldn't this compressor, if used in the opposite sense, extract energy from the hot gas? Lutz's description of his compressor is not clear to me. US2301667A - Rotary compressor and other engines - Google Patents I didn't know how a swing-piston engine looks. My interest is in plausible...

I was looking at unconventional IC engines when I came across Otto Lutz's swing piston engine. Contemporary German turbines were having trouble coping with high temperature produced by the combustion chamber. To solve this problem Lutz's engine was supposed to be put in as a gas generator. It...

That is all true, but that tendency to roll in the opposite sense exists in completely level flight too. Only it is balanced by aerodynamic forces. Once the plane departs from this position, the extra moment being applied is on top of the already existing moment used to counter engine torque. At...

It is often remarked that each aircraft has it preferred direction of roll, which is in the opposite sense to the propeller's rotation. Why should that matter ? While the aeroplane is in its trimmed condition there should be zero moment along the roll axis regardless of the engine torque. To...
