Design, Testing, and Simulation of an Experimental 105-mm M35 Fire Out-of-Battery (FOOB) Direct Fire Gun
Abstract
The work reported herein details the operation, simulation, testing, and shortcomings of a direct fire weapon (105-mm M35) that has been modified to operate in a fire out-of-battery (FOOB) mode. In FOOB mode, the firing sequence is radically different than that for a conventional weapon. The gun is captured and preloaded in its out-of-battery position prior to firing. This position compares to a conventional system's maximum recoil location. When unlatched, forward momentum is imparted to the recoiling parts, which will eventually be opposed by the ballistic force imparted by firing a round. The ballistic impulse imparted to the gun reverses the momentum and returns the recoiling parts to their latched position ready for the next round. Although the total momentum imparted to the system is not changed, the FOOB approach could theoretically reduce the transmitted loads to the mount structure by 75 percent.
