A group of scientists at the Massachusetts Institute of Technology (MIT) and George Mason University are working on a wetsuit for the US Navy, designed for use in cold Arctic waters. The project is funded by the Office of Naval Research (ONR).
The aim of the project is to create a diving suit in which divers can feel comfortable in icy water, like marine mammals – whales, walruses and seals.
In most of the current wetsuits, a combination of neoprene and a small layer of water heated by the diver's body is used to conserve heat, which provides him with an acceptable level of heat in waters with a temperature of 10 to 25 grams. FROM.
In a new waterproof suit, a heat-insulating layer of air in the pores of neoprene is replaced by heavy inert gases – xenon and krypton, which give neoprene properties similar to the fat layer of marine animals. To make such a substitution, it is necessary to put the wetsuit in a special tank and begin to pump in the inert gas there. Within a few hours, the gas penetrates into the pores and displaces the air.
According to experts from ONR, due to this, the suit keeps heat for several hours at temperatures up to 10 g. C. The dressing with gas is performed a few hours before diving. To prevent the gas from escaping, the treated wet suit is placed in a sealed plastic bag.
The product is currently tested in a laboratory. The next stage is sea trials involving civilian divers and Navy specialists.js.src = “&version=v2.8”; 'script', 'facebook-jssdk'));
