MARCHETTI MVT (S.50) Italy

  Designed by Alessandro Marchetti and built by the Vickers-Terni industrial organisation at La Spezia, the MVT single-seat fighter biplane was flown in 1919. Of all-metal construction, the MVT was powered by a 220 hp SPA 6a water-cooled engine and carried an armament of two synchronised Vickers machine guns. The fuselage, which was suspended between the upper and lower mainplanes, was flattened aft to emulate an aerofoil surface, and the semi-elliptical wings were of extremely thin section, lateral control being provided by wing warping. On 9 December 1919, the MVT recorded a speed of 155 mph (250 km/h) - absence of FAI officials preventing this being certified as a world speed record - and demonstrated the ability to climb to 16,405 ft (5 000 m) in 11 min. In 1920, the MVT was fitted with longer-span wings, splayed interplane bracing struts, a revised cabane and a redesigned horizontal tail. A 285 hp SPA 62a engine was fitted with which 171 mph (275 km/h) was attained under test at Montecelio. When Marchetti was appointed chief designer to SIAI, the MVT was redesignated S.50 and was entered in the official fighter contest of 1923. Three were supplied to the newly-created Regia Aeronautica for evaluation, but a plan to procure a batch of 12 failed to materialise. One S.50 was modified as a twin-float seaplane. The following data relate to the SPA 62a-powered MVT.
