M109A6 Paladin Self-Propelled Howitzer: Full Load, High Ambient Cooling Test and Follow-on Engineering Tests

摘要

Full load, high ambient cooling tests were conducted on a M109A6 Paladin vehicle in three different configurations. The intent was to verify cooling capability of the vehicle. The powertrain configurations tested included: (1) the baseline, a 440 horsepower Detroit Diesel engine with the Allison TC360 torque converter, (2) the baseline Detroit Diesel engine with an Allison TC396 torque converter, and (3) an up-powered 500 horsepower Detroit Diesel engine and the Allison TC396 torque converter. The vehicle did not meet its specified cooling requirements; however, it came close in configuration 3.
