Abstract:

Under Contract AF 08635-3745, initiated on 17 June 1963, an electronic, long-delay bomb fuze, the FMU-35B, was to be designed, developed, fabricated, and evaluated. By its development, the inherent disadvantages of the mechanical fuze, viz., unsuitability for supersonic flights and deliveries, low reliability, and potential safety problems were to be overcome. In the design and development of the fuze, those subassemblies of the existent FMU-26B Bomb Fuze generically common to the FMU-35B Bomb Fuze were modified, where necessary, for adaptation in the latter configuration. Through comprehensive programs of development, qualification, and Air Force engineering evaluation tests and through a comprehensive failure-analysis program, it has been possible to fabricate a long-delay fuze possessing a reliability in excess of 0.9 at a 90-percent confidence level. Concomitant with the engineering-evaluation program Phase III, an E-Cell concept for adaptation to the FMU-35B fuze was designed and developed. The innate simplicity of the E-Cell timer as a substitute for the electronic-timer subassembly in the FMU-35B, and its initial evaluative successes justify further consideration of the E-Cell concept.
