Comparison of Aeroprediction Methods for Guided Munitions
Abstract
Several aeroprediction methodologies were used to evaluate four munition configurations: a generic canard-controlled, subsonic projectile; a long strake-tail missile; a generic ogive-body-tail supersonic missile; and a generic high-speed munition. Numerous flight conditions of angle of attack, roll angle, and Mach number were investigated. The aeroprediction methodologies included inviscid and viscous computational fluid dynamics solvers and a semi-empirical aerodynamic design code. The results were evaluated for agreement with each other and with respect to experimental data in order to better determine the use cases and applications of these methodologies. The range of results revealed notable differences in how the methodologies handle unique flow features that occur for different geometries at different flow conditions.
