Abstract
An integrated Safe-Arm Device is an electrically activated, dual environm sensing mechanism which aligns a ball valve from a vented safe mode to a connected gas mode by sensing minimum sustained missile launch acceleration and minimum missile arming altitude prior to removing and setting various locks on the piston valve arming mechanism. The safing features have no stored energy and require the energy extracted from the environments to operate.
Claims7
An integrated safe and arm device (ISAD) for a missile which comprises:
- a housing for hermetically sealing said ISAD there within and for providing a controlled atmosphere therefor;
- exoatmospheric pressure sensor means operatively disposed in said housing for monitoring the reentry of said missile for sustained exoatmospheric flight;
- propulsion sensor means operatively connected to said exatmospheric means for monitoring the performance of said missile during the powered flight portion of said missile's trajectory;
- generator means for generating gas;
- pneumatic control valve means operatively disposed external to said housing for directing gas from said generator means to a safety valve vent when said control valve means is in a safe position and to a turbo alternator port when said valve means is in an armed position;
- motor and gear blocks assembly means operatively coupled to said propulsion sensor means and said exoatmospheric means for providing the mechanical force needed to lock and unlock said pressure and propulsion sensor means, and to arm and safe said valve means;
- and
- environmentally powered safety lock means for preventing motion of said propulsion sensor means, and said exoatmospheric means during ground transportation and storage.
