ANALYSIS OF BALLISTIC PERFORMANCE OF A GLIDE EXTENDED-RANGE PROJECTILE

摘要

The flight of a glide extended-range projectile with canard configuration is briefly described. A dynamics-based 6-DOF mathematical model of the glide extended-range projectile is constructed. With the aid of numerical simulation, effects of rocket ignition time, the matching of muzzle velocity and mass of projectile, rocket ignition time, angle of departure, and the starting glide control point on trajectory of the gliding projectile are evaluated. The result shows the technique of glide extended-range will improve the range greatly, and it also increases the flight time and decreases the falling velocity of the projectile. The maximum range angle has much difference with conventional no control projectile, the maximum range angle of the projectile is about 62°. The optimum control point of glide control is closed to the top of the trajectory. Besides, the property parameters of detecting apparatus and control rudder system are analyzed numerically.
