The Bernard SIMB V.2 was a single-seat, single-engine French monoplane, built in the mid-1920s. It was originally designed for racing but was adapted for a successful attempt on the world absolute speed record. ==Design and development== Design of the Bernard V.2 was begun at the same time as that of the Bernard V.1, with the intention of entering both models into the Beaumont Cup competition held in June 1924, but the V.2 was completed too late for entry and the V.1 was destroyed before the competition.〔 Bernard then decided to use the V.2 in an attempt on the world airspeed record〔 held for the U.S.A. by A. J. Williams in a Curtiss R-6 at 429 km/h (267 mph).〔 The nickname Ferbois was often used instead of SIMB, so the V.2 sometimes appears as the Bernard-Ferbois V.2.〔 The V.2 was a cantilever mid wing monoplane. Its all wood wings were built with multicellular construction around two parallel spars and the surfaces sanded and lacquered to reduce friction drag. In plan the wings were straight tapered, mostly on the trailing edge, with oblique tips. The ailerons were near triangular, reaching to the wing tips; there were no flaps.〔 Aluminium fairings blended the wing roots into the fuselage; similar fairings were used at the elevator roots.〔〔 The elevators had straight, swept leading edges and were set at the top of the fuselage. They carried separate elevators with a cut-out for rudder movement. The latter was wide and almost rectangular, its upper edge blending into an almost triangular, wide chord fin.〔 The wooden monocoque fuselage was equally refined and polished, its oval section tapering towards the tail. Towards the nose the fuselage flattened to accommodate the three four-cylinder blocks of its 340 kW (450 hp) W-12 Hispano-Suiza 12 Gb engine, driving a low-set two-blade propeller with a large spinner. This was water-cooled, with under-wing radiators from the root to half span, assisted by a single ventral radiator just aft of the undercarriage. The fixed, tricycle undercarriage had unfaired single mainwheels on a single axle, attached by bungee cord to two flat, faired, tapered legs. These legs were cross-braced with streamlined stays. The open cockpit was at the wing trailing edge. Because the Hispano engine of the V.2 was mounted lower in the nose than the Lorraine-Dietrich, another W-12, of the V.1, the central cylinder bank did not so completely obscure the pilot's forward view.〔 Some modifications, detailed below, were made to the V.2 before its successful attempt on the world speed record. The Bernard (or SIMB) V.3 was a proposed, unbuilt development with a retractable undercarriage and a Lorraine-Dietricht engine.〔 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「Bernard SIMB V.2」の詳細全文を読む スポンサード リンク
