Airbreathing Rotating Detonation Wave Engine Cycle Analysis
46th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2010 Abstract A cycle analysis model for an airbreathing, rotating detonation wave engine (RDE) is presented. The engine consists of a steady inlet system with an isolator which delivers air into an annular combustor. A detonation wave continuously rotates around the combustor with side relief as the flow expands towards the nozzle.
