Arming apparatus is installable between twin arming units (101, 102) of an ejector release unit in a military aircraft, and a single fuzing unit (74) of a store (78). The arming apparatus comprises sequentially breakable links (221, 222, 223) which ensure reliable ejection of the store in an armed state, or jettisoning of the store in an unarmed state, as desired.

A coupling mechanism securing a first object having a well to a second object having a lug, including a shuttle movable within the lug, a resilient biasing means biasing the shuttle away from a base of the well when the lug is inserted, and locking elements movable radially in the lug between a retracted position and an extended position. Each locking element moves from the retracted position and retains in the extended position by a surface profile of the shuttle. The coupling mechanism includes a movable stop having: a first position in which movement of the shuttle is limited so the locking elements interact with the surface profile, and a second position in which movement of the shuttle is extended to cause the locking elements to interact with another surface profile of the shuttle, moving the locking elements from their extended position to their retracted position.

A coupling mechanism (10) for securing a first object (16) to a second object (24) comprises a well (14) formed in or securable to the first object and a lug (22) formed on or securable to the second object. A shuttle (34) is movable within the lug (22). A first resilient biasing means (48) is arranged to bias the shuttle (34) away from a base of the well (14) when the lug (22) is inserted in the well. A plurality of locking elements (36) are each movable radially in the lug (22), between a retracted position allowing free insertion and withdrawal of the lug (22) into and from the well (14), and an extended position in which the locking element (36) projects into a recess (38) formed in a side wall of the well so as to lock the lug in the well. Each locking element (36) is movable from the retracted position and retained in the extended position by a first surface profile of the shuttle (34). The coupling mechanism (10) comprises a movable stop (30, 32, 42, 44) having: a first position in which the biased movement of the shuttle (34) is limited so that the locking elements (36) interact with the first surface profile of the shuttle (34), and a second position in which the biased movement of the shuttle (34) is extended so as to cause the locking elements (36) to interact with a second surface profile of the shuttle (34) which moves the locking elements (36) from their extended position to their retracted position, thereby allowing withdrawal of the lug (22) from the well and disconnection of the first and second objects (16, 24).
F16B 21/16 - Means without screw-thread for preventing relative axial movement of a pin, spigot, shaft, or the like and a member surrounding itStud-and-socket releasable fastenings without screw-thread by separate parts with grooves or notches in the pin or shaft
A store suspension lug assembly comprises a base securable to a store and a lug portion hingedly movable between an extended position in which it is engageable by a suspension hook of a release unit and a retracted position presenting a lower aerodynamic profile. The lug portion is biased towards the retracted position. A locking mechanism has a locked state in which the lug portion is held in the extended position. The locking mechanism is releasable by action of the suspension hook on the lug portion, e.g. by the suspension hook engaging a portion of the locking mechanism as the weight of the store acts on the suspension hook via the lug portion. Engagement of the suspension hook with the lug portion may maintain the lug portion in the extended position against the bias.

The arming apparatus comprises sequentially breakable links which ensure reliable ejection of the store in an armed state, or jettisoning of the store in an unarmed state, as desired.

An e.g. fluid powered linear actuator is provided with a helical orientation surface in a fixed angular position relative to a first component; and a follower in a fixed angular position relative to a second component. When the first and second components are moved towards one another as the actuator is retracted, the follower engages and moves along the helical orientation surface to rotate the first and second components to a predetermined relative angular position.

A small store suspension and release unit uses a resiliently biased electrical connector assembly and/or resiliently biased feet pivotally attached to adjustable sway brace legs to apply an ejection impulse to a store after release from a suspension hook. A safety latch mechanism includes a pawl which engages a nib on the suspension hook assembly to prevent inadvertent release of the store if the suspension hook assembly becomes jammed, e.g., due to ice formation.

A two-stage, fully self-retracting, telescopic fluid actuator suitable for high speed ejection applications comprises a detent 38, 64, 26, which locks a cylinder 6 in an extended position for extension of a piston 3 therefrom. The detent is released by retraction of the piston into the cylinder again, e.g. under spring bias, so that the actuator is fully self-retracting. A locking ball 38 of the detent also serves to latch the piston and cylinder to each other for the first stage of the actuator extension. In an alternative embodiment, cam means (80, 117 FIGS. 10, 11 and 13) and plungers (90, FIGS. 10, 12, 13 and 15) perform the detent and latching functions.
