FMU-65/B FUZE DEVELOPMENT.
Abstract
The FMU-65/B fuze was designed to provide impact initiation to the BLU-39/B23 CS munition in the CBU-30 system without altering the skittering action of the munition. After arming problems were corrected, tests were conducted with the FMU-65/B fuze housed in the BLU-39/B23 canister. The CS pyrotechnic mixture burning rate was too erratic to allow the use of the fuze case as an orifice to produce skitter. When it was determined that no satisfactory variable orifice could be attached to the fuze within the canister, the fuze was placed on top of the canister where it could ignite the CS pyrotechnic mixture and then be ejected so that the BLU-39/B munition could burn and skitter as designed. Satisfactory functional results were obtained on bench and MIL-STD environmental and safety tests; however, flight tests on a sample of 37 fuzed munitions showed that some environments of the CBU-30 system prevented proper arming of the fuze. It is suspected that either a high munition tumbling rate, or fuze contamination from the burster charge is the cause; however, the contract allowed no opportunity to evaluate this condition.
