Abstract : Idenifiers: Piston actuator, Time delay squibs, Dimple motor, Caterpillar, Bellons motor, Guillotine switch, Monroe effect. The design, operation and application of various pyrotechnic and auxiliary rocket devices, including considerations of safety, failure modes and circuit design, are discussed. The conclusion is reached that the use of small pyrotechnic devices and auxiliary rocket systems makes possible the programming of nearly all desired functions in a free-flight research model. Further, that in spite of the detailed analysis and preflight testing required of these devices, their design and operational simplicity provide a higher degree of afety and reliability than comparable mechanical or electromechanical programming systems. In addition, the small size of these devices reduces model costs or, alternatively, increases the amount of data that can be obtained from a flight model of a given size, since more units can be incorporated.
