Pulsed detonation engine: Key issues

Abstract

We examine key issues that determine pulsed detonation engine (PDE) propulsive efficiency. Using Computational Fluid Dynamics methodology (CFD), we conducted performance analysis for the device for which we demonstrated multi-cycle operation experimentally. The analysis is focused on the effects of the non-ideal detonations on the propulsive efficiency. General questions of the methodology of nonsteady engine cycle analysis and performance evaluation are examined.
