Abstract:

The existing Calspan model of the 175mm gun was upgraded to represent the 105mm howitzer. The primary items that were added to the basic code were a representation of metal primer tube with an initial paper liner and use of single and multiperf M1 propellant in specific bags of the propellant charge. In addition, improvements were made to the basic code which included the treatment of projectile motion, the addition of relative quickness and force as program input parameters, and improvement of the basic propellant drag function. The program was run extensively in an attempt to determine a unique set of barrel resistance parameters that would satisfy all zones and to determine the basic sensitivity of propellant properties.
