Microclimate Cooling System (MCS)

1081

Microclimate cooling system (MCS) is provided as part of US Army Air Warrior program, for helicopter crews, operating in the hot climate of Southwest Asia. It is designed to offset heat stress from air crews operating for extended durations under full NBC protected gear. This system protects the individual from heat stroke and heat stress. Equipped with MCS, helicopter crews wearing NBC protection gear can safely endure 5.7 hour mission, compared to 1.6 hours without such protection. The microclimate cooling garment is worn as an undergarment beneath the body and closing. The garment is connected to a condenser unit which chills water and pumps it through small tubes embedded in the vest.
