Thermodynamic Cycle Analysis of Pulse Detonation Engines
William H. Heiser,David T. Pratt +1 more
TL;DR: In this paper, a closed thermodynamic cycle analysis of the Pulse Deletion Engine (PDE) was presented, where the most important result was the thermal efficiency of the PDE cycle, or the fraction of the heating value of the fuel that is converted to work that can be used to produce thrust.
Journal ArticleDOI
Numerical investigation of the physics of rotating-detonation-engines
TL;DR: In this paper, the role of inlet stagnation pressure and back pressure on the performance of rotating-detonation-engines (RDEs) was investigated and it was found that the detonation wave height and mass flow rate are determined primarily by the stagnation pressure, whereas overall performance is closely tied to pressure ratio.
