Lock mechanism for a thrustreverser

摘要

A lock for a thrust reversal system of a gas turbine engine includes a pivotal locking member (5) which is moved into the locking position by the engagement of a part (8) of the thrust reversal system as the latter is moved to the inoperative position. The locking member (5) is held in the locking position by a pin (15) which engages within an opening (16) formed in the locking member. The pin (15) is biased by a spring and is movable by a hydraulic piston against the action of the spring to withdraw the pin from the opening.
