Abstract
Methods, apparatus, systems, and articles of manufacture are disclosed. An example locking assembly for an arresting hook system includes a track coupled to a frame of an aircraft. The track includes a forward end and an aft end opposite the forward end. The track includes a first lock positioned at the forward end and a second lock positioned at the aft end. The locking assembly includes a guide coupled to a hook shank of the arresting hook system. The guide is to move along at least a portion of the track, engage the first lock when the hook shank is in a stowed position, and bypass the second lock as the hook shank moves from the stowed position to a deployed position.
Claims21
A locking assembly for an arresting hook system comprising:
- a track coupled to a frame of an aircraft, the track including a forward end and an aft end opposite the forward end, the track including a first lock positioned at the forward end and a second lock positioned at the aft end;
- and
- a guide coupled to a hook shank of the arresting hook system, the guide to move along at least a portion of the track, the guide to engage the first lock when the hook shank is in a stowed position, the guide to bypass the second lock as the hook shank moves from the stowed position to a deployed position.
An arresting hook system for an aircraft comprising:
- a trapeze deployment assembly;
- a hook deployment assembly including a hook shank and a hook, the hook deployment assembly pivotally coupled to the trapeze deployment assembly;
- and
- a locking assembly coupled to a frame of the aircraft, the locking assembly including a passive lock and a directional lock, the passive lock to retain the hook when the hook deployment assembly is in a stowed position, the directional lock to enable the hook to bypass the directional lock when the hook deployment assembly moves from the stowed position to a deployed position, the directional lock to retain the hook of the hook deployment assembly in an intermediate position when the hook deployment assembly moves from the deployed position to the stowed position.
An aircraft comprising:
- an arresting hook system including:
- a trapeze deployment assembly;
- a hook deployment assembly including a hook coupled to a hook shank, the hook shank including a roller;
- a pivot assembly to pivotally couple the trapeze deployment assembly and the hook deployment assembly;
- and
- a dual lock coupled to a frame of the aircraft, the dual lock including a track defining a first end and a second end opposite the first end, the dual lock including a passive lock positioned at the first end and a directional lock positioned at the second end, the passive lock including a pocket to receive the roller when the arresting hook system is in a stowed position, the roller to bypass the directional lock when the arresting hook system moves from the stowed position to a deployed position, the directional lock to capture the roller when the arresting hook system moves from the deployed position toward the stowed position, the directional lock to capture the roller when the arresting hook system is in an inspection position prior to the hook moving to the stowed position.
