Abstract
A locking system to secure a trans cowl to a frame of a thrust reverser on an engine of an aircraft. The locking system includes an arm that is connected to the trans cowl with the arm having a receptacle. A lock includes a body and a pin with the pin movable relative to the body and with the lock positionable between a locked position and an unlocked position. In the locked position, the pin is in an extended position relative to the body that extends into the receptacle to secure the trans cowl in a stowed position. In the unlocked position, the pin is in a retracted position relative to the body that is away from the arm to enable the trans cowl to move to a deployed position.
Claims20
A locking system to secure a trans cowl to a fixed structure of a thrust reverser on an engine of an aircraft, the locking system comprising:
- an arm that is connected to the trans cowl at a forward end, the arm comprising a receptacle;
- a lock comprising a body and a pin with the pin movable relative to the body and with the lock positionable between a locked position and an unlocked position with the lock positioned in front of the forward end of the trans cowl;
- an anchor comprising a base configured to be mounted to the fixed structure and a flange that extends outward from the base, wherein the lock is mounted to the flange to be spaced away from the fixed structure;
- an opening in the flange with the opening aligned with the pin for the pin to extend through the opening and through the receptacle of the arm when the pin is in an extended position;
- wherein in the locked position, the pin is in the extended position relative to the body that extends through the receptacle to secure the trans cowl in a stowed position;
- and
- wherein in the unlocked position, the pin is in a retracted position relative to the body that is away from the arm to enable the trans cowl to move to a deployed position.
A locking system to secure a trans cowl to a fixed structure of a thrust reverser on an engine of an aircraft, the locking system comprising:
- locking combinations that are mounted to the fixed structure, each of the locking combinations comprising:
- an arm that is connected to the trans cowl, the arm comprising a first opening;
- an anchor mounted to the fixed structure and comprising a second opening and a third opening;
- a lock mounted to the anchor and comprising a movable pin;
- wherein the locking combinations are selectively movable between a locked position and an unlocked position;
- wherein in the locked position the arm extends through the third opening and the pin extends through the first opening of the arm and the second opening of the anchor to secure the trans cowl in a stowed position;
- and
- wherein in the unlocked position the pin is away from the first opening to enable the trans cowl to move to a deployed position.
