The purpose of the report is to determine the basic characteristics and limitations of the system of crew compartment ventilation employed at the present time in the M4 and M5 tanks as related to the protection provided to the crew members. The purpose of ventilation of the fighting compartment in a tank is to insure, as far as possible, a reasonably safe atmospheric environment and one in which the efficiency of the crew will not be seriously impaired. The most important functions of crew compartment ventilation are control of gun fumes removal of excess heat effective heating of crew in cold weather control of dust protection against chemical warfare agents. Crew compartment ventilation in the M4 and M5 tanks is provided as a by-product of the engine ventilation and is not subject to independent control. This system of negative- pressure ventilation is wholly incapable of meeting certain of the desired functions of crew compartment ventilation and meets the others only in part. A complete discussion of the characteristics and limitations of ventilation in the M4 and M5 tanks is presented.
