Abstract

A 35mm cluster armor piercing ammunition physical model was established, and then the drag coefficient and aerodynamic force in different Mach number were calculated using Fluent software. To reduce the mechanical jamming in the discard moment, resizing the front cavity dimensions was needed. Finally, the dynamic characteristics with different front cavity dimensions in discard moment were calculated, and this got preparation for later discarding analysis.

Key words： cluster armor piercing ammunition; drag coefficient; fluent numerical analysis; pressure distribution; sabot armor piercing
