I'm a bug fan of the wankel rotary engine, and I've just disovered
stirling power recently.
If stirling pistons are 90deg out of phase, and wankel rotors are
180deg out of phase, (180 = 90*2) it would seem to me that the
hot/cool gases can simply be ported to a 90 degree postion in the
rotor's sweeping motion, and quite naturally too.
In a two rotor setup the front rotor could be the hot side, with the
rear rotor being the cold side, with internal porting back and forth
going through the intermiediate housing. (perhaps containing a
For introducing heat/cooling my thoughts were to modify the rotor
housing's water jackets, One liquid cooled, the other fire fed.
The benefits I can imagine are: 3 moving parts, conservation of
momentum, nil vibration, and the ability to oil the rotors and
ecentric shaft without leaking oil into the working chambers.
Has this been attempted or discussed before?
