Preliminary Evaluation 20MM Plastic Rotating Bands.
Abstract
Experimental exploratory evaluations of plastic bands applied to ammunition for the M139 gun consisted of obtaining and evaluating data provided by comparison firings between projectiles having either plastic or copper bands in two ballistic environments, the M139 and M61 gun barrels (Mann) over the temperature range -65 deg F, +70 deg F, and +160 deg F. In all, 120 projectiles were fired, 60 in each environment and 10 of each band material at each conditioning temperature. In addition, photographic observation of representative in-flight projectile firings provided visible evidence of band integrity, projectile stability, and band deformation.
