Analysis of internal ballistic load environment and simulation verification methodology for fuzes of high-angle artillery ammunition
The fuze is the critical actuating component that enables high-angle artillery ammunition to achieve its terminal effects. Its performance directly impacts the coordination between the artillery ammunition and the firing system, thereby determining the probability of destruction of aerial targets by the high-angle artillery ammunition, and to a significant extent influencing the outcome of the war. This paper analyzes the primary loading conditions experienced by the fuze of high-angle artillery ammunition within the gun barrel, and discusses the methods of performance simulation and experimental verification. The analysis and research presented in this paper can provide valuable reference and inspiration for the structural design and performance simulation of high-angle artillery ammunition fuzes in the future.
