120MM Gun Heat Input Measurements

Abstract

Imbedded thermocouples just beyond the engraving region have been used to measure total heat input in guns. The method has been applied to the XM256 cannon to estimate erosion. Rounds were fired with JA2, M30, M6, and M1 propellants with various charge to mass ratios. Efforts were made to measure total heat input without the combustible case. Total heat input was reduced from 387 J/mm to 247 J/mm in a series of rounds with 0.3 kg silicone ablative as a wear-reducing additive.
