  • Patent number: 4032090
    Abstract: A method for deicing an aircraft having ice formed on its outer skin comprises heating a water solution substantially free of glycol to a temperature from approximately 160.degree. to approximately 190.degree. F. The water is then sprayed in a stream onto the skin under atmospheric conditions whereby the heated water will loosen the ice and wash the ice from the skin. The excess water solutionwhich falls from the airplane is drained away. The heated water forms a film on the skin and warms the skin to prevent additional ice from forming thereon. Under certain atmospheric conditions, the heated water film will evaporate from the skin, thereby chilling the skin and drying it so as to minimize the sticking of blowing snow and ice on the skin. The method minimizes the amount of glycol required for anti-icing.
