Cumin Josip, Grizelj Branko, Scitovski Rudolf. Numerical solving of ballistic flight equations for big bore air rifle

Technical Gazette 16, 1 (2009), 41-46 pp.This paper is about solving ballistic equations by means of numerical mathematics. Ballistic flight equations are applied for modern big bore air rifles, operated with high pressure carbon-dioxide (CO2) gas. Ballistic equations use air drag function for obtaining results. Today there are many complex commercial ballistic programs on market, based on modified mass point model –"MPMM" or "6DOF" model. Big bore air rifle commonly uses ball projectiles, and velocities of the projectiles are lower than the speed of sound. Therefore simplified models for quick calculations of ballistic trajectories and projectile velocities can be used.
