Feasibility Demonstration of a Dual Pressure Sensing Safing and Arming Mechanism for Air Delivered Submunitions

摘要

The design objective of this study was to demonstrate feasibility of the dual pressure sensing safing and arming (S and A) mechanism which was designed to arm on receipt of a low pressure signal supplied in the dispenser and the high pressure pulse associated with the propellant dispersion event. Following extensive tests of an original dual pressure S and A mechanism design, work was directed toward analysis of a miniature design. The miniature S and A mechanism was evaluated in a series of tests, and, with final modifications, the desired performance was demonstrated to establish mechanism feasibility.
