Air cushion landing systems have large doughnut-like structures, on the bottom of the fuselage, called trunks. The trunks form the ducting for the air cushion. According to this invention, use is made of the large quantity of air which flows through the trunks. In the present system, the air in the brake pillows is virtually static so that they form excellent insulators, which inhibit the flow of heat through the pillow to the air flowing through the trunks. The heat pump principle is used to transfer heat across the space in the braking pillows. A liquid adjacent the braking surface is evaporated and the liquid is then condensed at the wall adjacent the air flow within the trunk. The condensed liquid then flows back to the wall adjacent the braking surface.
