Simulation and Analysis of Centroid Motion Characteristics of Uncontrolled Spinning Projectile on the Plateau

Abstract

On the plateau, the aerodynamic forces and moments of uncontrolled rotating projectiles in flight have changed greatly compared with those in the plain, which will inevitably affect the trajectory of the projectiles. In this paper, the motion characteristics of projectile moving around the center of mass on Plateau were analysed through the simulation of six-degree-of-freedom rigid body trajectory under Plateau conditions. It is found that the degree of motion around the center of mass increases and the attenuation of rolling motion slows down under Plateau conditions. According to the research results, the paper proposed some suggestions on the use of uncontrolled spinning projectiles under Plateau conditions.
