Abstract: A modified linear model is proposed for fast and accurate prediction of short and long-range trajectories of spin-stabilized bullets via atmospheric flight to a final impact point. This model is compared with a full 6-DOF trajectory model. The computational flight analysis takes into consideration the Mach number and total angle of attack effects by means of the variable aerodynamic coefficients.

Keywords: Low and high pitch angles, projectile trajectory, variable aerodynamic coefficients
