초록 ▼

A mechanical lock for an airplane engine thrust reverser is connected to an actuator for the thrust reverser sleeve. The mechnical lock includes an electrically operated solenoid which moves a locking pin between an unlocked position and a locked position. When the pin is in the locked position, it engages a toothed wheel which is mounted about a shaft which engages a drive gear for the thrust reverser actuator. In this manner, movement of the thrust reverser sleeve is prevented until commanded operation of the thrust reverser whereby the locking pin is moved to the unlocked position.

대표청구항 ▼

An airplane thrust reverser system comprising: a. means for redirecting air which is propelled in a rearward direction by an airplane engine in a nonrearward direction; b. actuator means, for moving the air redirecting means between a stowed position where the air is not redirected and deployed position where the air is redirected in the nonrearward direction; c. means for automatically moving the actuator means, in response to an input, so as to move the air redirecting means between the stowed position and the deployed position; d. means, which are engaged with the actuator means, for synchronizing operation of the air directing means between the stowed position and the deployed position; e. means for manually moving the actuator means, the manually moving means including means for receiving a tool which is manipulated by an operator outside of the airplane when the airplane is on the ground in a manner that movement of the tool by the operator in the tool receiving means causes movement of the actuator means so as to move the air redirecting means between the stowed and deployed positions; f. first means which is engaged between the manually moving means and the synchronizing means such that movement of the manually moving means by the operator causes movement of the first means so as to cause movement of the synchronizing means which in turn causes movement of the actuator means and the air directing means therewith; and g. second means which is movable between a first position for stopping movement of the first means thereby stopping movement of the synchronizing means and actuator means therewith, and a second position for allowing movement of the first means thereby allowing movement of the synchronizing means and the actuator means therewith.
