RESEARCH ON THE DESIGN OF AIR BURST FUSE OF LITTLE DIAMETER SHELL BASED ON COUNTING ROTATION NUMBER FOR DISTANCE MEASUREMENT
Abstract:Three key technologies referred to the design of air burst fuze of small caliber gun using the method of distance setting by counting rotation number is discussed. They are the design of the fast activating power, the increase of the distance setting accuracy by counting rotation number, the structure minimization to meet the requirement of the limited space of small caliber ammunition. The distance setting accuracy by counting rotation number is affected by the air resistance, so the method of conic numerical simulation to refine counting rotation number for distance measurement is introduced. Taking the experimental data and combining several influence factors, it is proved to be well by the practice.
Keywords:distance setting by counting rotation number  air burst fuse  piezoelectric power  refinement of counting rotation number
