I have heard and seen developments in the technology and idea which is to also use the liquid or ‘hydraulic fluid’ as a cooling agent for the pilot’s body.
We were trials guinea pigs for the liquid-cooled suit for the Tornado some 10 years before it entered service. Unlike the air ventilated suit the LCS was in close contact with the body. This meant that the coolant had to be circulating on the ground to avoid heat stress. We had to carry a liquid ice refrigeration pack, just like the Astronauts, but it made a pre-flight walk around much more difficult.
Had we bailed out the first thing on landing would have been to strip the suit off. It was not proceeded with but it may have found a use in glass furnaces.
