FEASIBILITY STUDY OF AN AUXILIARY PROPELLED 155MM HOWITZER CARRIAGE, M1A2, PHASE IV
Abstract
A description is given of the fabrication and preliminary testing of 3 prototype models of the 155mm auxiliary propelled howitzer carriage XM123. The prototype design was prepared to overcome some shortcomings of the experimental vehicle built under phase II of the task. Overcoming the deficiencies of the experimental vehicle were the design goals of the study; namely, to increase ground clearance at wheel transmissions, to decrease jacking time, to redesign caster for more mud clearance and more abuse, t decrease total kit weight, to reduce amount o exposed plumbing, and to provide emergency operation if an engine fails. Further improvements were made in eliminating the worm gear in the wheel transmissions, providing a echanical linkage between the pump swash plate and motor swash plate and placing the hydraulic reservoirs between the trails. From the preliminary test reports received, it appears that the deficiencies ound are minor. (Author)
