Abstract
An uplock system includes a cam plate comprising a cam channel, a hook configured to rotate with respect to the cam plate, a follower rotatably coupled to the hook, wherein a portion of the follower moves within the cam channel in response to rotation of the hook, a stopper configured to engage the follower, and a first biasing member configured to bias the stopper towards the follower to stop the follower from moving within the cam channel, thereby locking the hook in a locked position.
Claims20
An uplock system, comprising:
- a cam plate comprising a cam channel;
- a hook having an opening, the hook configured to rotate with respect to the cam plate;
- a stopper configured to rotate with respect to the cam plate;
- a first biasing member configured to bias the stopper in a first rotational direction relative to the cam plate;
- and
- a follower rotatably coupled to the hook, wherein a portion of the follower moves within the cam channel;
- wherein the first biasing member is configured to bias the stopper in the first rotational direction to stop the portion of the follower from moving along the cam channel and secure the hook in a locked position.
An uplock system comprising:
- a cam plate comprising a cam channel;
- a hook configured to rotate with respect to the cam plate;
- a follower rotatably coupled to the hook, wherein a portion of the follower moves within the cam channel in response to rotation of the hook;
- a stopper configured to engage the follower;
- and
- a first biasing member configured to bias the stopper towards the follower to stop the follower from moving within the cam channel, thereby locking the hook in a locked position.
A method of operating an uplock system comprising:
- rotating a landing gear towards a deployed position, wherein the landing gear comprises a latchable member;
- contacting, by the latchable member, a hook, wherein the hook is configured to rotate with respect to a cam plate;
- rotating the hook in a second rotational direction in response to the contacting;
- moving a follower along a cam channel in response to the rotating of the hook, wherein the cam channel is disposed in the cam plate and the follower is rotatably coupled to the hook;
- contacting, by the follower, a stopper, wherein a load is transmitted from the follower into a first biasing member in response to the follower contacting the stopper;
- and
- moving, by the stopper, away from the follower, in response to the load overcoming a spring force of the first biasing member.
