ABSTRACT:
A new type of gas heat engine is described that has several features similar to a gas turbine or jet engine. The engine is developed in many different configurations, each yielding different theoretical advantages and degrees of freedom. All of this family of engines have no moving components, provide heat recovery and operate over a wide range of input gas velocities. The new engines can use higher combustion temperatures and consequently have the potential for improved efficiency over current technology.There are many theoretical and practical advantages to the new concepts, which give flexibility in both engine design and operating characteristics that are difficult to embody in current turbo jets. Among the most important is the potential for a thermodynamic efficiency which exceeds that of current open cycle gas heat engines at a given pressure ratio.A new term in the equation of the Enthalpy of a gas is described, which could be exploited in yet other variants of the engine.An application of special interest that emerges from this work is the potential to design first stage rocket boosters.The substantiative benefits of the new engines are improved safety to aircraft, fuel economy, reduced engine weight, and cost. Furthermore, the engine concepts can be scaled to create engines of any desired size and power output without the conventional mechanical limits associated with gas turbines.
