ScienceNASA’s rotating detonation rocket engine and its potential for more compact propulsion
A post says NASA’s 3D-printed full-scale combustor fired for 251 seconds in a 2023 test, producing more than 5,800 pounds of thrust.

Posts describe NASA’s Rotating Detonation Rocket Engine (RDRE) as using supersonic detonation waves that race around a circular combustion chamber instead of a conventional steady flame. They frame higher efficiency, more compact propulsion and reduced engine complexity as potential benefits. One cites a 2023 test in which a 3D-printed full-scale combustor fired for 251 seconds and produced more than 5,800 pounds of thrust, and says the technology could eventually support lighter propulsion systems for lunar landers and deep-space missions.
