B.F.Goodrich [[[4 images]] 4 hot ideas for fighting ice The pipe that files like a plane. Boeing's new Flying Boom for in-flight refueling (upper left) is actually flown into places by means of vee-shaped ruddevators. To provide accurate control, these ruddevators had to be protected against ice. B.F. Goodrich developed special electric rubber pads for the leading edges that supply spot anti-icing heat. Electric blankets keep new Arctic plane from freezing. Designed for Arctic rescue work, Northrop's new C-125 (upper right) had to have ice protection at all vital spots. BFG electric rubber "blankets" turned the trick for three parts-antenna mast , elevator horn and air scoops. Because of the design flexibility of electric rubber, wide variation in the shape of these three parts proved no obstacle. Keeps ice from choking jet's throat. Ice forming in the narrow "throat" of the jet engine intake could choke off the air supply, make the engine quit cold. This threat has been eliminated on North American's B-45 (lower left) with a special lining of BFG electric rubber inside the cowl. Rubber makes gasoline stretch. To help flight engineers adjust fuel supply for maximum efficiency, a hydraulic line transmits propeller load to an instrument panel dial. But cold was congealing the oil, causing false readings. BFG engineers sheathed the hydraulic line in electric rubber to keep the oil fluid, save gasoline. This heated line is now standard on TWA Constellations (lower right). B.F. Goodrich electric rubber is tough, thin rubber with a core of resistance wires that provide spot heat precisely as needed. Two lead wires attached to the airplane's regular power supply are the only other equipment required. Electric rubber can be made to fit any size, any shape airplane part.
