Development of the FMU-65/B Fuze for Use with the CDU-12/B Cluster Bomb.
Abstract
The design and development of the FMU-65/B fuze and its application to the CDU-12/B cluster bomb is presented in this report. The CDU-12/B is a cylindrical cluster of 32 CS pyromix-filled submunitions and is carried in and delivered by the SUU-13/A dispenser. The original CDU-12/B contained submunitions with a fixed time delay pyrotechnic fuze. The FMU-65/B is a mechanical replacement for the pyrotechnic fuze. It provides omnidirectional impact function of the submunition and provides greater flexibility for delivery. During this program a functional reliability of 97 percent at a 90 percent confidence level was demonstrated for the FMU-65/B fuzed submunition. Flight tests were conducted during the development program by Eglin AFB and Flight Test Research (FTR) to demonstrate the acceptability of the FMU-65/B fuze in the CDU-12/B. The primary problems encountered were the adverse effects that the cluster expulsion event had on the function of the fuze and the provision for successful submunition skittering once the CS generation event occurred. The incorporation of the FMU-65/B fuze necessitated minor changes to the cluster assembly and to the construction of the CS pyromix submunitions. These design effects along with the problems and their resolutions or recommendations for further development are delineated in this report. (Author)
