AERODYNAMIC COEFFICIENTS FOR EXTENDING AND BENDING PROJECTILES

摘要

We address the general problem of calculating the trajectory of a cone-cylinder-flare projectile which extends in flight. The projectile is both pitching and bending. The extension affects the pitching, bending and subsequent flight in significant ways. To facilitate the quick and transparent calculations of the aerodynamic coefficients as they change during extension, we have developed a simple model which agrees well with the results of detailed numerical calculations.
