This aviator heat stress study used a mixed betweenwithin test subject design with one environmental condition hot and three rotary-wing MOPP4 ensembles Special Operations Aviation Regiment SOAR, Air Warrior Concept 1, and Air Warrior Concept 3 encumbered with ballistic protection and over-water survival components. The SOAR ensemble was tested with SC and without SX microclimate cooling MCC consisting of a water-cooled undershirt with portable refrigeratorpump. Air Warrior Concept 1 and Concept 3 aviator MOPP4 ensembles were tested with AC and without AX MCC, respectively. Physiological and subjective data were obtained to compare thermoregulatory responses and quantitate the benefits of microclimate cooling. Test sessions consisted of a 20-minute treadmill walk in a heated 100 deg F and 20 percent relative humidity RH environmental chamber to stimulate outdoor preflight activities, followed by three 2-hour sorties in a research UH-60 simulator with cockpit conditions set at 1000F and 50 percent RH 90 deg F wet-bulb globe temperature WBGT.
