Abstract

In order to study the effect of rocket projectile's aerodynamic configuration on its ballistic characteristics, rocket projectile models with different aerodynamic configuration were designed. Flow field numerical simulation was conducted for rocket projectile models under different Mach number flying condition by ANSYS FLUENT and the aerodynamic characteristic parameters were obtained for each rocket projectile model. For analyzing the effect of aerodynamic configuration on fire range, a particle trajectory model is established for trajectory simulation using the aerodynamic characteristic parameters obtained. Results show that the firing range change within 0.08-164.53 m can be provided by the optimized rocket projectile models. Research results can provide theoretical and technical support for rocket projectile's aerodynamic configuration optimization design and its engineering application.

Key words： aerodynamic configuration; rocket projectile; ballistics characteristic; numerical simulation
