Abstract Scope |
Pressure gain combustion, particularly in the form of a rotating detonation rocket engine (RDRE), is an attractive power cycle for SWaP-constrained space propulsion applications. One of the largest hurdles to realizing the benefits of an RDRE is designing the combustor for long life in the harsh, high heat flux detonation environment. The focus of this research is on achieving combustor longevity using a regeneratively cooled rocket engine configuration. The interaction between thermo-mechanical stresses from thermal gradients, cooling channel pressurization, and ultrasonic detonative loading is studied in detail. The key insight from this research is that maximizing the operational life of the combustor requires tailoring the combustor geometry and combustor material to avoid resonance with the rotating detonation wave. This is achieved by judicious selection of the combustor wall thickness, cooling channel parameters, and combustor material. |
