THE INCENDIARY EFFECTIVENESS OF HEI FILLERS IN 20MM PROJECTILES
Abstract
The major performance feature of interest in these tests, however, is the ability of the projectile to produce fuel fires in an aircraft under varying conditions of attack. An important characteristics of incendiary projectiles, is the maximum distance from projectile impact to an aircraft fuel cell wall, both laterally and along the profectile trajectory, at which a fuel fire can be obtained. Considerable, but incomplete, data had been obtained prior to the firings described in this report. The general expectations for the two types of targets used are substantiated in that: (1) when the trajectory of the projectile is perpendicular to the fuel cell wall (B-2 mockup target), higher percentages of incendiary mix generally increase the incendiary effectiveness of 20mm rounds; (2) when the trajectory is parallel to the fuel cell wall (Miss- Distance target), higher percentages of incendiary mix decrease the maximum distance at which fuel fires can be caused. The addition of two grams of 20 - 60 mesh, Tyler screen, in the base of the T282E1 projectile did not enhance the incendiary performance of this round. The modification of the T216E1 utilizing a steel slug in the shell cavity has promise for increased ammunition effectiveness.
