USA: natural antifreeze could also be applied on airplanes

A study carried out by Virginia Tech researchers

The formation of ice on the outer surface of aircraft is one of the most dangerous phenomena; airlines and manufacturing companies invest billions of dollars to avoid efficiency losses and mechanical failures caused by freezing. Thanks to a research carried out at Virginia Tech -published today in the scientific journal "ACS Applied Materials & Interfaces"- but soon this problem could be overcome, because it has been proven a solution that allows to keep 90% of the surface without ice in all conditions, without using chemicals.

A "simple" approach that allowed researchers to create an anti-freeze surface on untreated aluminum modeled in such a way as to create a series of microscopic grooves -occupying 10% of the total area-, where the ice is intentionally formed to create a series of low pressure areas that drag moisture away from the frozen surface. Study that has demonstrated its possible applicability even in conditions of lower temperature of very zero. According to researchers, this technology could be applied primarily in the field of air conditioning systems, but in the future it could be very useful also for aerospace materials such as wings and aircraft fuselage.
