Boundary-layer Trip Effectiveness and Computations of Aerodynamic Heating for XM797 Nose-tip Configurations

Abstract

The Army is examining a new concept for limiting the range of the training round for the M735 projectile. This training round, designated the XM797, now employs an explosive placed within the nose cap which is ignited by aerodynamic heating. This report documents results of a recent firing program conducted at the BRL Transonic Range in which M735 projectiles with modified nose-tips were tested. The purpose of these tests was to determine the effectiveness of boundary-layer trips in generating turbulent boundary layers on the projectile nose. Also reported are results of computations of the in-depth temperature response of XM797 nose-cap configurations for several flight conditions.
