Computational Study of Inbore and Inflight Heating for the 105MM, M774 Projectile Modified Swept Fin.

Abstract

Fin stabilized kinetic energy penetrator projectiles, such as the M774, have occasionally suffered from severe reduction in fin span due to inbore heating, inflight aerodynamic heating, or a combination of both. This report describes a computational investigation of the inbore and inflight thermal response of the M774 modified swept fins of aluminum and steel composition. The calculations demonstrate that both the inbore and inflight heating of the fin are significant, and that the steel fin shows an improved thermal response over the aluminum fin.
