摘要

Temperatures and concentration measurements taken in the detonation channel of a hydrogen and air rotating detonation engine (RDE) using laser absorption spectroscopy are presented. Measurements are taken at four axial locations within the RDE over a range of equivalence ratios, mass flow rates and air injector geometries. The resulting absorption spectra are used to determine gas temperatures versus time. These measurements allow for the characterization of the transient temperature response of the RDE.
