Partial rept. no. 1
ARMY ARMOR AND ENGINEER BOARD FORT KNOX KY
Pagination or Media Count:
Test objectives were to assess the capability of the compressor to withstand the vehicle environment to determine if the compressor, the remainder of the scavenger system, and the restowage of the turret is compatible with crew functions to determine time required to recharge the compressed air bottle, and to assess the bottle capacity and compressor recharge rate with regard to its adequacy for firing missions, and to describe any residue not cleaned by the scavenger. Results are based on operation of the compressor for 50 hours, firing of 58 rounds, and movement over paved and unpaved roads and cross country for 496 miles. Restowage of the turret components was in general compatible with crew functions. Time required to recharge the air bottle from minimum firing pressure of 1,000 psi to maximum pressure was 31 minutes. No burning residue experienced in firing 58 rounds. Nonburning residue was evident in breech cavity after each round. Reliability deficiencies include hose failure, compressor contact point failure, water in system. USAARENBD concluded duration of test was insufficient to determine suitability. USAARENBD recommended additional testing be conducted on a system modified to correct all deficiencies and as many shortcomings as feasible.
