Abstract

The subject of this thesis is the development of ahighly ruggedised, reliable electronic circuit. The circuit is to be used for the initiation of fuze heads and to charge a capacitor for later use in apyrotechnic chain. This circuit and its associated packaging will be called the firing unit. The thesis can be broadly divided into the following facets. I. The definition study, which defines what is needed and proposed means of achieving the customer requirements. 11. The design of the electronic circuitry in the system. Ii!. The design of the packaging containing the electronics. Iv. Adaptation of environmental testing, to verify system design. V. Implementation of environmental testing. Vi. Reliability analysis. Vii. Failure analysis and the determination of the effect of the supposed failure. Actions vto vii were used as inputs to improve 11 and ill, so achieving optimum performance and safety. The whole system was designed with the overriding objective of reliability and safety of personnel and equipment.
