The use of pyrotechnic devices in missiles and space vehicles creates a hazardous environment for equipment. Several reported flight anomalies concurrent with the separation event prompted Lockheed Missiles & Space Co. to devote considerable effort to establish methods of treating pyrotechnic shock. An extensive ground testing program included activation of the vehicle’s pyrotechnic systems and subsequent measurement of the shock.
Several methods of improving confidence in equipment performance during pyrotechnic shock by means of electrical modifications, shock mounting, and testing were investigated.
In addition to treatment of present shock problems, a program was initiated to reduce the pyrotechnic shock levels in the vehicle by redesigning the booster separation joint. Several methods of achieving a qualification testing system for equipments is included in the discussion of the system and specification which LMSC presently uses.
The present status of the shock problem with future proposed LMSC effort is also discussed.
