Evaluation of squib performance variables
The use of Kinetic Energy Device for measuring the output of a pyrotechnic squib or actuator was presented in the proceedings of the Thirteenth Pyrotechnic Seminar held in Grand Junction, Colorado 1988. This device was demonstrated as a valuable tool for evaluating the interface design between the squib and the next assembly. The thrust of this investigation was to evaluate the amount of containment that the interface provides and its effect on the amount of energy transmitted to a moving piston on the other side of the interface. Experiments were repeats of tests done with another test device known as the Variable Explosive Chamber. This data was presented in the proceedings of the Twelfth Pyrotechnic Seminar held in Juan-les-Pins, France 1987. A second area of investigation was to determine the effects of variation in the average compaction density and total mass of pyrotechnic powder load on the performance of the squib. The data shown here is for one specific geometry but may have implications to other geometries and even to other devices such as ignitors or matches. The equations of motion are examined for two geometries of test actuators. Pressure pulse curves are derived from the displacement versus time records for the extremes of a constant density, variable mass test series. 4 refs.
