Aerojet has concluded the second series of vibration and altitude hot-fire tests on its thrust mono-propellant rocket engine, MR-104 to be used on Nasa’s Orion spacecraft.

The test aims to characterise engine performance after the thruster is subjected to Orion crew module vibration loads.

It produced energy levels three times the previously qualified levels after vibration loads were applied, verifying the engine’s design and capability to withstand substantially higher vibration loads.

The post-vibration altitude hot-fire test sequences tracked the thruster’s health over its operating range to ensure the mission performance requirements after being subjected to Orion vibration loads during launch.

The engine reached at least 175lb of thrust during steady-state firing, showing an Orion contingency operation during an abort mission.

The current Orion crew module flight configuration includes 12 MR-104G engines operating at 160lb of thrust.
