Abstract: 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.

Abstract: 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.

Abstract: Arming apparatus is installable between twin arming units of an ejector release unit in a military aircraft, and a single fuzing unit of a store. 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.
