Abstract

The performance of an idealized pulse detonation turbine engine (PDTE) was thermodynamically analyzed. In the analysis, both of detonable and inert gases were dealt with as the working media taking account of the differentiae of a PDTE against a conventional gas turbine engine utilizing isobaric combustion. Further, the thermodynamic states of the working media at the inlet of the turbine were estimated. As an example, the performance of a hydrogen-fueled PDTE was calculated. By comparing the performances of internal combustion engines utilizing detonation, isochoric combustion, and isobaric combustion, it was shown that a PDTE has a potential for being a higher-performance engine than a conventional gas turbine engine utilizing isobaric combustion.
