A thermodynamic model is presented for the external and internal combustion process for the fuel flexile engine described in Part I. The model describes the thermo-dynamic and flow processes involved in partially burnt gases from the precombustion chamber thrusting into the power chambers and thence further combustion in the power chambers. The model consists of two parts: a flow simulation of the thrust process and a thermo-dynamic simulation of the internal combustion by using a three zone sub-model for combustion. The results are presented graphically for engine performance prediction and parameter optimization.

A unique, fuel flexible engine is being developed. It is a true rotary engine in that the motion of the rotors is truly rotational and does not have any reciprocating or epitroichoidal motion. The engine has an external precombustion chamber with main combustion occurring in the engine itself - this makes the engine fuel flexible. A physical working model has been constructed, run on compressed air and has demonstrated successfully the design concepts. In this paper the engine design, physical working model construction and operation as well as the results of computed engine performance are presented.
