A TEST TO DETERMINE THE CAUSE OF BARREL EROSION IN THE 40MM M75 LAUNCHER

Abstract

The objective of this study was to determine the effect on the 40mm M75 Gun barrel wear using four different cartridge case systems (using the M169 Cartridge Case series). On the basis of test results, the present two-piece cartridge should be replaced with a single-chamber cartridge case. Although the two-piece cartridge case with talc additive produces results comparable with the single-chamber case, use of the single-chamber case would result in substantial cost savings as well as eliminating a source of system malfunctioning. This gun is part of the M5 Weapon System for Helicopters.
