STINGER Launch and Flight Motor Squib Electrical Safety and Functional Performance Evaluation.

摘要

This report provides the measured electrostatic sensitivity, resistance, no-fire current, all-fire current, ramp current, step current, and the Bruceton firing current estimated standard deviation values for the STINGER launch and flight motor squibs. The tests included one lot of 250 launch motor squibs and two lots of flight motor squibs (one contained 145 and the other 346). The values obtained from these evaluation tests exceed the Atlantic Research Corporation's specification requirements. One exception was the above tolerance pin-to-pin resistance value of 33% of the first lot of flight motor squibs. The high resistance did not adversely affect the functional performance. Another exception was the firing of one squib from the first lot of flight motor squibs near the end of the 1-ampere, 1-watt, 5-minute no-fire test. (Author)
