Experimental Investigation of Flame Anchoring Behavior in a LOX/LNG Rocket Combustor
Aerospace, 2023 Hot fire tests of a multi-injector research combustor were performed with liquid-oxygen and liquefied-natural-gas (LOX/LNG) propellants at chamber pressures from 30 up to 67 bar, hence at conditions similar to an upper stage rocket engine.
