Influence of Aerodynamic Loads on Flight Trajectory of Spinning Spherical Projectile

摘要

The effect of lift and drag forces and aerodynamic moment on the flight of a spinning projectile in the atmosphere is investigated. The influence of the spin rate of the projectile on the range and height of flight is also studied, taking into consideration the progressive decay in the spin rate during the flight. The governing equations of motion of the projectile have been solved numerically, and the results are presented graphically. The effect of various parameters such as angle of projection, initial velocity, and spin on the flight of projectiles are plotted.
