Comparison of the 120-MM M831A1 Projectile's Experimental Launch Dynamic Data with Hydrocode Gun-Projectile Dynamic Simulations

Abstract

This paper documents experimental validation for numerical simulations using the U.S. Army Research Laboratory's (ARL) gun-projectile dynamic simulation codes. The experimental program was conducted at ARL's Transonic Range Experimental Facility on the M831A1 high-explosive antitank (HEAT) training projectile for the M256 gun system. The experimental program consisted of the M831A1 HEAT training projectile fired for the measurement of aerodynamic characteristics. Measured first maximum yaw levels are compared to simulated data for the same system. The effect of damage tubes to help explain occasional launch anomalies is also shown.
