Static Aerodynamics CFD Analysis for 120-mm Hypersonic KE Projectile Design

Abstract

Computational fluid dynamics (CFD) predictions of static aerodynamic coefficients for large caliber (120-mm) M829-like cone-cylinder-flare kinetic energy (KE) projectile shapes are presented. Zero-yaw drag and static pitch- plane aerodynamic coefficients are presented for velocities in the range 1.5 to 3.0 km/sec for several flare angles. The aerodynamic coefficients are required to assess the velocity retardation and static stability of candidate configurations that use the M829 projectile as a basis for design. Comparisons of the aerodynamic coefficients are made with those of the fielded M829 projectile, and a preliminary evaluation is made of the performance of these shapes in hypersonic flight.
