Title Systems Analysis and Design Calculations for a kind of Submunition Fuze of Multifunction Cargo Projectile
Abstract
For a submunition fuze reliability and security in handling problems, there are still some shortcomings, conducted after improved the submunition fuze system analysis, performance calculation and strength check. Through the strength of the shell and fuze fuze body calculations, as well as the submunition within the system, such as a weak spring unit checked to make submunition fuze structural strength to meet the requirements. By sitting on the submunition Insurance fuze performance, safety performance centrifugal slider parts start condition, the role of anti-restore-off performance calculations correctness to ensure reliable insurance and the role of submunition fuze. In addition to self-destruct ignition device for calculating the performance of the submunition fuze usually assess safety, while the strike movement combination of acupuncture hair extension tubes for energy calculations. The results show that the improved strength of the submunition fuses meet the requirements, to ensure recoil insurance, such as the role of the centrifugal insurance and sliders reliable peacetime security, self-destruct good performance. The results show that the fuze arming reliable, angry reliable, trigger and self-destruction; meet the overall requirements of the cargo projectile.
