Abstract: A safety device for preventing an airborne charge (1) from being armed prior to being dropped, said charge being armed by a draw wire (4) connected to the aircraft applying traction to an arming cable (3) connected to the charge. The safety device comprises a clamping assembly (2) through which the arming cable (2) passes freely while the clamping assembly is open and is clamped thereto when the clamping assembly is closed. The clamping assembly (2) comprises first and second parts (5, 7) which are movable relative to each other in the traction direction (T) of the draw wire (4), with said first part (5) being a "fixed" part which is fixed to the charge by threshold releasable fixing means (6a, 6b) sensitive to traction in said traction direction (T), and said second part (7) being slidably mounted to move relative to the charge in said traction direction (T), and being connected to the draw wire (4).

Abstract: A control mechanism is provided for tripping a system in a releasable missile. The control transmission which controls tripping of the system comprises an energy store held under stress by a locking member. The locking member is designed to be actuated on completion of unwinding of the storage pulley thereby to release the energy store and so initiate tripping of the system connected to it. The invention has a particular application in releasable missiles such as bombs which are transported by aircraft.
