TEST TAKEOFF OF BOMBER EQUIPPED WITH CATERPILLER-TYPE LANDING GEAR.
The first takeoff and landing of the Air Force's experimental XB-36 bomber equipped with a caterpillar-type track landing gear was made on March 29, 1950, at the Fort Worth Division of Consolidated Vultee (Convair) Aircraft Corporation. With the track-type gear, the weight of the XB-36 rests on Bogie Wheels rolling on two endless belts on each main landing gear strut. Two smaller endless belts are installed on the nose gear strut. The gear, which is retractable, is the latest step in the Air Force's program of track-type gear development. The track on the main landing gear is designed for a maximum average of 57 pounds pressure per square inch on the landing strip, as compared to a pressure of 156 pounds per square inch exerted by the conventional wheel-type gear on a B-36 at the same gross weight. The Bogie Wheels around which the track travels are made of a new magnesium alloy containing zirconium, giving the wheels an especially high impact resistance. Friction is reduced to a minimum by the use of 185 tapered roller bearings weighing approximately 500 pounds. Released Washington, D.C. April 12, 1950. The caterpillar-type landing gear was fitted primarily to gather test data when fitted to a very heavy aircraft. The original main landing gear design with a single large wheel and tire was redesigned in the late 1940s and fitted to all production B-36s and retrofitted to the XB-36 and YB-36. The new landing gear arrangement had a two wheel nose gear and four wheel mains. "Troy24" wrote in message 3... |
