NASA’s 3D-printed Rotating Detonation Rocket Engine Test

Test stand video captured at NASA’s Marshall Space Flight Center in Huntsville, Alabama, shows ignition of a full-scale Rotating Detonation Rocket Engine combustor, which was fired for a record 251 seconds and achieved more than 5,800 pounds of thrust.

Engineers at NASA’s Marshall Center successfully test-fired an innovative Rotating Detonation Rocket Engine combustor, a potentially revolutionary propulsion technology that could deliver a lander to the lunar surface or propel a spacecraft to Mars.
