Computational Study of Swept-fin Aerodynamic Heating for the 105mm M774
The 105mm M774 is a high velocity, long 1/d, fin stabilized projectile. Recent test firings by LCWSL at Yuma Proving Ground, Arizona, revealed that the stabilizing fins were being severely reduced in span due to aerodynamic heating. This brief computational study examines the in-depth temperature response of a thin, swept fin to aerodynamic heating for a series of fin geometries in an effort to determine if a minor design modification can be found which will result in improved performance of the swept fin. The computational results indicate that the aerodynamic heating can be significantly reduced by a relatively small increase in the sweep angle of the fin.
Computational Study of Inbore and Inflight Heating for the 105MM, M774 Projectile Modified Swept Fin
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.
