Prediction of Wear Characteristics of Artillery Propelling Charges.

Abstract

Tube wear characteristics were assessed for modification to propelling charges M119A1 and M203 (for 155-mm howitzer) and to propelling charge M188E1 (for 8-inch howitzer). The modifications involved a charge in the ignition system for the M119A1, a change in wax type in the wear reducing liner of the M203, and a charge in propellant (from M30A1 to M31A1) and change of amount of wear additive in the M188E1. Comparison of relative total heat input to the gun tube is used to predict the effect on wear characteristics when charges of similar ballistics characteristics are compared. The modifications for the M199A1 and for the M203 did not affect tube wear characteristics of the charges. However, the modifications to the M188E1 (M188A1) are expected to double the wear life of the M201 gun tube observed with the M188E1 charge.
