High-bandwidth absorption-spectroscopy measurements of temperature, pressure, CO, and H2O in the annulus of a rotating detonation rocket engine
The development and application of two laser-absorption-spectroscopy diagnostics capable of performing high-bandwidth measurements of (1) temperature, pressure, and CO, and (2) temperature and H 2 O in the annular combustion chamber of a rotating detonation rocket engine (RDRE) are presented. The mi...
