Abstract : A guided missile fuze comprising a safety-arming mechanism. Upon intentional launch of the missile the explosive train of the fuze is mechanically and electrically aligned, provided prescribed launch and flight events occur and a specific time has elapsed. The first step in the arming cycle of the present invention is the transmittal of intent to launch logic to the fuze by the pilot just prior to launch. This connects power to the fuze and removes a solenoid interlock from the mechanism. At separation the movement of a rod used to enable the rocket motor initiating device removes a second mechanical interlock from the device. After separation initiation of the rocket motor causes hot gas pressure to be applied to a piston located in the rocket motor section external to the fuze and interfacing with a plunger that extends from the safety-arming mechanism. Action of the piston on the fuze plunger applies arming energy to the mechanism. The mechanism is driven to a second solenoid interlock (Committo-arm condition) impeded by the action of an escapement. Completion of arming cannot occur until the second solenoid interlock is removed. The logic signal to remove this interlock is generated by the missile guidance when the missile comes in close proximity to the target. (Author)
