Engine Burnout

Acceleration phase, before engine burnout or shutdown.

Propellant exhaustion (burnout) will result in the following:

• Ammonia or oxygen manifold pressure drops, with consequent shutdown (of the engine) by low manifold safety circuit;

• Pump cavitates, with consequent overspeed (pump and engine) cut-off.
