Abstract
In a microwave de-icing system for the front areas of exposed shell structures, at least one independently operable microwave generator is disposed in each shell structure closely adjacent the surfaces of the shell structure to be de-iced or kept free of ice and uncoupling means are flanged to the microwave generators with uncoupling openings disposed along the area of the shell structure to be heated so as to provide a microwave wave front directed toward this area. The area subjected to the wave-front includes walls of a dielectric composite material with a metallic skin whereby the microwave front penetrates into the wall and is converted at least partially into heat within the wall of composite material thereby providing for rapid and effective heat supply to the wall areas of the shell structure to be kept free of ice.
