Mhz-Rate Laser Spectroscopic Instrument For Reacting Flow Composition And Temperature Measurements Inside Rotating Detonation Engines (Rdes)

Abstract

Rotating Detonation Engines (RDEs) is a concept with the potential of realizing a pressure gain architecture that will lead to improved efficiency in power generation and propulsion systems. However, there are many questions on stable operation and effectively recovering flow such that it may be used in power production. To this end, a Tunable Diode Laser Absorption Spectrometer (TDLAS) was developed which targets H2O at two wavelengths for resolving the composition and static temperature of the working medium within an RDE combustion channel. Coupling this information with velocity measurements, the total pressure may be resolved. Preliminary results from application of the sensor to hydrogen fired Aerojet Rocketdyne engine test are discussed.
