Rotating Detonation Rocket Engine (RDRE) Development

The contract focuses on the research, design, and testing of Rotating Detonation Rocket Engines powered by storable propellants, with an emphasis on understanding and enhancing combustion stability across various operating conditions. Efforts will include analytical and experimental validation to ensure predictable and sustained detonation wave behavior, critical for reliable engine performance. The project aims to advance the scalability of these engines to flight-weight configurations suitable for practical aerospace applications, bridging laboratory-scale successes with real-world operational requirements. Development work will be performed at Edwards, California, with a submission deadline of August 10, 2026, and the contract is classified as a subcontract under the NAICS code 336413, indicating its alignment with aerospace and defense propulsion systems. The awarding agency is the Department of Defense through the FA9300 Aftc Pzr office, underscoring the strategic importance of this technology for next-generation propulsion systems. The project is part of a broader initiative to mature rotating detonation engine technology toward flight readiness, prioritizing durability, efficiency, and integration with existing spacecraft architectures.
