ABSTRACT:
A safe jettison device for aircraft stores is used to avoid unintentional ming of aircraft stores when they are jettisoned vice intentionally dropped. A coil is inserted in a conduit which prevents removal of the arming line unless the coil is skewed by a preset pulling force. If the store is released without skewing of the coil, the coil remains in the conduit and does not permit the arming line to be initiated. An activation device is held to the aircraft by a force less than the force needed to pull the coil free until an arming signal is given. Once an arming signal is given, the activation device holds with a greater force than that needed to pull the coil free.
