Air Force Researchers, Gawi Healthcare Develop Lightweight Cooling Tech for Military

USAFSAM cooling techThe U.S. Air Force School of Aerospace Medicine and its partner Gawi Healthcare have developed a small, lightweight, passive cooling technology in an effort to reduce heat stress under a cooperative research-and-development agreement.

A July 13 post on the Defense Department science blog says Reginald O’Hara led a USAFSAM exercise physiology research team to develop a cooling sleeve or wrap for the water bladder and a variant with cooling inserts for a specially designed undershirt.

“Military personnel exposed to excessive heat for an extended period of time may experience reductions in both physical and cognitive performance,” said O’Hara.

“Those reductions could severely limit their ability to carry out their duties during intense ground and flight operations.”

Team members field-based tests on the sleeves to see if the product could maintain or reduce the temperature of the water during exposure to heat and humidity and performed tests on the undershirts that showed the shirt inserts helped lower core body temperatures.

The Government Accountability Office has found that the U.S. Air Force intends to start fielding in fiscal 2020 new Combat Rescue Helicopters to replace aging HH-60G Pave Hawk helicopters that have recorded the most flight time when it comes to staff recovery missions. GAO said in a report published Thursday the service will initially deploy the new helicopters to the active component six years ahead of the reserve component and to the Air National Guard by 2027.
