Design and Development of Very Long Delay Fuze (Phase 2)
Abstract
A design was developed to demonstrate the feasibility of a ground- settable Very Long DELAY Fuze for use in air-delivered bombs and mines with standard fuze wells, and which is capable of eventing the munition at a preselected time which is selected from a range of event times. The delay range extends from 20 seconds to 30 days after impact, and the delay is selected before take-off. Laboratory tests of complete developmental models demonstrated that the fuze was capable of functioning properly after an impact environment characteristic of the delivery profile of a 750-pound general purpose bomb. Safety features were developed to comply with MIL-STD-1316. The explosive train was developed to meet the requirements of MIL-STD-331, Test 115. The fuze is powered by a reserve ammonia battery (output of 2.8 to 4.5 volts). A fuze model similar in physical and functional characteristics to the ground-settable fuze was developed to demonstrate the feasibility of using the fuze with an AN/AWW-4 Fuze Function Control Set for the Purpose of Selecting an event time from the cockpit. The cockpit-settable capability was demonstrated successfully, along with the use of complementary metal-oxide semiconductor (CMOS) circuits for timing functions. It was shown that the use of CMOS circuits would provide a fuze of greater accuracy than could be achieved through the use of E-cells.
