Abstract

This study investigates Rotating Detonation Engines (RDEs) using gaseous hydrogen and oxygen as propellants, .... Experimental campaigns explored the influence of injector design and operational parameters on detonation regimes, revealing a broad range of sustained regimes. The findings align with existing literature, highlighting the potential of hydrogen-oxygen RDEs for propulsion applications. Further research is needed to optimize RDE stability and fully harness their capabilities.
