The Vickers Windsor was a Second World War British four-engine heavy bomber, designed by Barnes Wallis and Rex Pierson at the Vickers-Armstrongs factory at Brooklands in World War II. ==Design and development== The Windsor was designed to Air Ministry Specification B.5/41 (later modified to Spec. B.3/42) for a high-altitude heavy bomber with a pressurised crew compartment, and an ability to fly at at .〔Andrews and Morgan 1988, pp. 387–388.〕 Notable features of the Windsor included its pressurised crew compartment, four mainwheel struts (one extending from each of the engine nacelles and carrying a single balloon-tyred wheel), elliptical planform high aspect ratio wings, and guns mounted in barbettes at the rear of each (outboard) nacelle, which were to be remotely operated by a gunner in a pressurised compartment in the extreme tail. The Windsor used Wallis's geodetic body and wing structure that Vickers had previously used in the Wellesley, Wellington and Warwick bombers. Instead of doped Irish linen however, a stiff and light skin was used on the Windsor, made with woven steel wires and very thin (1/1000 inch thickness) stainless steel ribbons, doped with PVC or other plastic, specially designed to avoid ballooning. To properly fit the skin to the frame, a tuning fork had to be used. The wings' structure had no spars. Instead, it was a single hollow geodetic tube from tip to tip, passing through the fuselage truss. To better resist the compression and tension efforts, the elements were assembled at 16 degrees next to the root, reverting to the more conventional ninety degrees on the tips, longitudinal elements locking everything in place. The elements' thickness was also reduced towards the tips. No two joints had the same angle on the wing, an authentic production engineer's nightmare. The wing was designed so that the tips had a noticeable droop on the ground, but was straight in flight, so the skin had to be fitted tighter on top than on the bottom to be evenly tight in flight. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Vickers Windsor」の詳細全文を読む スポンサード リンク
