Rocket rotating detonation engine flight demonstrator

Aircraft Engineering and Aerospace Technology, 2016
Purpose Today’s modern liquid propellant rocket engines have a very complicated structure. They cannot be arbitrarily downsized, ensuring efficient propellants’ mixing and combustion. Moreover, the thermodynamic cycle’s efficiency is relatively low.

Numerical simulation of a methane-oxygen rotating detonation rocket engine

Proceedings of the Combustion Institute, 2021
Abstract The rotating detonation engine (RDE) is an important realization of pressure gain combustion for rocket applications. The RDE system is characterized by a highly unsteady flow field, with multiple reflected pressure waves following detonation and an entrainment of partially-burnt gases in the post-detonation region.

Thrust Performance of Converging Rotating Detonation Engine Compared with Steady Rocket Engine

Journal of Propulsion and Power, 2023
Rotating detonation engines (RDEs) have been actively researched around the world for application to next-generation aerospace propulsion systems because detonation combustion has theoretically higher thermal efficiency than conventional combustion.

Thermal and Structural Characterization of a Rotating Detonation Rocket Engine

AIAA SCITECH 2024 Forum
Improving launch vehicle and satellite propulsion system performance directly correlates to the delivery of more mass (or quantity) on orbit from launch vehicles, longer duration satellite missions, and longer ranges for missiles/interceptors. Alternative propulsion devices such as rotating detonation engines (RDEs) offer the potential for significant ...

Investigation of Nozzle Performance for Rotating Detonation Rocket Engines

2019
Progress in conventional rocket engine technologies, based on constant pressure combustion, has plateaued in the past few decades. Rotating detonation engines (RDEs) are of particular interest to the rocket propulsion community as pressure gain combustion may provide improvements to specific impulse relevant to booster applications.
