Design of Experiments Study of the Initial Extended Area Protection and Survivability (EAPS) Projectile System

Abstract

A novel approach is proposed for assessing the effects of gun barrel centerline variations on Extended Area Protection and Survivability (EAPS) projectile launch dynamics. The technique of experiment design was adopted to simulate an array of deformed gun tubes representing reasonable manufacturing tolerance. Subsequently, in-bore structural analysis of the EAPS projectile system subject to the simulated gun barrels was performed. The projectile responses, including transitional and rotational velocities at the muzzle, were obtained. The analysis of variance method was then used to identify the sources of variability and to determine the significance of each gun shape. Based on the response statistics, no erratic launch conditions should be expected for the EAPS projectile because of normal barrel centerline variations.
