Abstract : "Aerodynamic jump for a non-spinning kinetic energy penetrator is neither a discontinuous change in the jurisdiction of motion at the origin of free flight, nor is it the converse, i.e. a cumulative redirection over a domain of infinite extent. Rather aerodynamic jump, for such a projectile, is a localised redirection of the centre of gravity motion, caused by the force of lift due to yaw over the re1atively short region from entry into free flight until the yaw reaches its first maximum. The primary objective of this paper is to provide answers to the questions like what is aerodynamic jump, what causes it, and what aspects of the flight trajectory does it refer to, or account for.
