Exploration Of Measuring Pressure Gain Combustion Within A Rotating Detonation Engine

Abstract

Exploration of pressure gain within a Rotating Detonation Engine is investigated to determine maximum efficiency. Aerojet Rocketdyne’s Rotating Detonation Engine at Southwest Research Institute was used to find velocity measurements using Particle Image Velocimetry. Six unique cases, using three different exhaust nozzles and two different pressure ratios per nozzle were studied. The nozzles at the exhaust plume were implemented to act as back pressure that would closely resemble that of a gas turbine as well as take the rotational behavior of the flow and linearize it. As the velocimetry measurements are presented, it is noticeable that the flow becomes linearized with a smaller chokes and higher pressures.
