Abstract:

An evaluation of heating and erosion of several candidate charges to be used in 155mm and 105mm tubes was performed. Test data were obtained in field testing of actual cannons using sensitive thermocouples and special Calspan erosion sensors. The following significant results were obtained 155mm Cannon 1. The charges employing the greatest additive showed erosion performance approaching that of the M119, whereas the original XM201E2 charge showed significantly higher erosion than the M119. 2. The XM201E2 charge employing 19 oz. internal wear additive resulted in less heat input at the origin and lower erosion than the other internal designs of lower additive weight. 3. The 19 oz. internal additive design resulted in less heat input and the same erosion compared to the 12 oz. jacket external additive design. 105mm XM204 Howitzer 1. Measured heating and erosion in this howitzer was found to be much lower than that of the 155mm cannon. Critical examination of all significant heatingerosion factors indicates the XM200 and XM622 to have about the same erosion performance with the XM200 charge showing very slightly lower heating.
