Influence of Initial Disturbance on Flight Trajectory of Uncontrolled Projectiles on the Plateau

摘要

Initial disturbance will cause nutation motion of projectile and affect aerodynamic force, thus affecting the altitude flight trajectory of uncontrolled projectile. Through the analysis and simulation of angular motion caused by initial disturbance under plateau conditions and the simulation calculation of the variation of ballistic parameters with position altitude under the same initial disturbance conditions, it was found that the influence of initial disturbance on plateau ballistics decreases under plateau conditions. As for the change of ballistic parameters, it has great influence on range, lateral deviation and maximum ballistic height, but little influence on full flight time and falling speed.
