DECELERATION AND MASS CHANGE OF AN ABLATING BODY DURING HIGH-VELOCITY MOTION IN THE ATMOSPHERE,

Abstract

This memorandum examines the factors affecting the dynamics and mass loss of ablating bodies moving at high velocities in a gaseous medium. The interdependent deceleration and rate of mass loss make the problem more complex than the simple case of deceleration of a body of constant mass. Although a solution exists for the classic meteor case with constant heat-transfer and drag coefficients, results have not been available for cases where these coefficients vary during the deceleration process, e.g., large bodies moving in the lower atmosphere. Some analytic solutions are presented for specific variations of the heat-transfer coefficient and suggests an approximation for other types of variations.
