Abstract
An electro-mechanical mechanism is disclosed which controls safety-armingring of an air-launched missile's rocket motor and safety-arming of the warhead. The mechanism has an out-of-line safety pyrotechnic design to maintain the electric firing circuits and explosive train in an open, safe position until a complete sequence of events occurs. Similarly, a second sequence must occur before warhead arming can proceed.
Claims8
A composite safing and arming mechanism for a missile launched from an aircraft having a warhead;
- and a rocket motor, said mechanism comprising:
- a mechanism casing connected between said rocket motor and said warhead;
- a port in said mechanism casing communicating with said rocket motor for allowing pressure therefrom to enter said casing;
- means for receiving an initial signal from said aircraft attached to said mechanism casing;
- means for initiating the rocket motor after a predetermined time attached to said casing adjacent the rocket motor;
- and
- means for arming the warhead attached to said mechanism casing after receiving a predetermined amount of pressure through said port from said rocket motor.
