Abstract
A hydraulic lock for a thrust vector actuator includes a lock cylinder. The lock cylinder includes at least one slot and at least one bore. The slot is defined through a perimeter of the lock cylinder, and the bore is defined through a portion of the lock cylinder at a second end to extend towards a first end. The hydraulic lock includes at least one biasing member coupled to the bore. The hydraulic lock includes at least one pawl having a first pawl end and a second pawl end. The first pawl end is releasably coupled to the shaft of the thrust vector actuator. The second pawl end is coupled to the slot. The pawl is movable relative to the slot between a first, locked position in which the first pawl end is coupled to inhibit movement of the shaft, and a second, unlocked position.
