OSTI ID:6062365
A pyrotechnic actuator has been developed utilizing new design concepts and materials. The new design features include a non-oriented connector, an electrostatic shield for safety, an output-end seal to eliminate initial free volume, and a retaining washer to prevent movement of the pyrotechnic during exposure to high G loads and thermal cycling. New materials in the actuator include a titanium subhydride/potassium perchlorate pyrotechnic for reduced spark sensitivity and a moldable baria/lithia/silica glass ceramic insulator for economy and high pressure burst strength. The glass ceramic has been specially formulated to have a thermal expansion coefficient which minimizes residual seal stress and permits greater actuator design flexibility.
