Arthur A. Koszoru, Irvin C. Stobie. Comparison of 155-mm gun tube heat input with solventless and solvent propellant
(Артур А. Кошору, Ирвин С. Стоби. Сравнение нагрева артиллерийского ствола 155-мм орудия при использовании порохов с и без растворителя).
Technical Report. - Aberdeen proving ground, Maryland: US Ballistic research laboratory. 1990. – 80 p.
A test to measure wall temperatures of a 155-mm howitzer cannon was conducted at the Ballistic Research Laboratory as part of a Product Improvement Program (PIP) which was formulated and conducted under the auspices of the Armament Research, Development, and Engineering Center. The main objective of this ballistic study was to determine if the projected gun tube wear from an alternative, ballistically equivalent, 155-mm, M203A1 propelling charge containing solventless stick propellant is comparable to the wear produced by the standard M203A1 containing M31A1E1 solvent based propellant. The results of this study indicate that the solventless propellant charge does not appear to be more erosive than the standard M203A1 charge. Additionally, the effects of several of the charge constituents on the amount of heat transferred to the tube were investigated, with a particularly dramatic increase seen in heat transferred to the tube when the case was removed.
