Title Systems Analysis and Design of an Aviation Fire Bombs Fuze
Abstract
Forest fire is open, fierce, unapproachable, easily resurgence .In order to meet the design demand of the fuze of aviation fire bombs, the fuze was designed through analyzing system, demonstrating firing device, explosive train, interrupter device, safety and arming device, delay arming device, self-destruction device, sterilization device, inputting whole program and describing fuse structure and acting process. Designing the tension of fuze and wind turbine, calculating and verifying strength and performance of parts, calculating spring resistance and dimension chain(of 42) and drawing two-dimensional design(of 47) and three-dimensional image. With the high reliability of explosion ,have the function of self-destruction , sterilization abilities and adjustable fuze arming delay distance ,suffice the relevant requirements about GJB 373A-1997《Fuze Design ,Safety Criteria For》,has the engineering design value.
Keywords Aviation fire bombs fuze system analysis design
