Abstract:

The investigations were conducted to establish the feasibility of incorporating a high voltage switch within the electrical header of an exploding bridgewire initiator and to determine the electrical capabilities of the voltage switch to meet missile safety and functional requirements. Two types of high voltage switches were designed, developed, and fabricated within the electrical header of an EBW initiator. The electrical capabilities of these voltage switches were evaluated under various environmental conditions. Their conformance to the required design parameters established the feasibility of including a high voltage switch within the electrical header. Various stand-off gap switch SOGS and stand-off voltage switch SOVS engineering models were studied in the feasibility investigation. Fifty prototype SOVS initiator headers of the final design configuration were fabricated. These units, designed for a coaxial input, utilize the electrical voltage breakdown characteristics of an aluminum-oxide coating for the voltage switch.
