Abstract: A method for smooth approximation of drag functions was proposed. Approximations of russian 1943 drag function and G1, G2, G5, G6, G7, G8, GI drag functions were constructed. The optimal grid step was determined by the Rihardson method of posterior error estimation to solve exterior ballistic task using smooth approximations of drag functions.

Keywords: ballistics, wind resistance, approximation, posterior error estimation, numerical techniques, Runge–Kutta method.
