The CVV-6 Canguro ((英語:Kangaroo)) was a high performance two seat glider, designed at Milan Polytechnic University in 1940. A small batch was ordered for the Italian Air Force but few were delivered; more were produced after World War II, becoming the most common Italian gliding club machine. Some were still in use in the 1980s. In 1954 a Canguro came second at the World Gliding Championships at Camphill Great Hucklow, Derbyshire, England. One was modified into a powered aircraft, at first with a piston engine and later with a turbojet. ==Design and development== The CVV-6 Canguro was one of a series of gliders designed at the Centro Studi ed Esperienze per il Volo a Vela (CVV) of the Politecnico di Milano between 1934 and 1957. The centre often outsourced the construction of their designs and the first two Canguros were built by the Aeronautica Lombarda,〔 with the first flight in 1941 or 1942.〔〔 Most of the later aircraft were built by Società d'Aeronautica Italiana Ambrosini,〔 with the result that the type is sometimes referred to as the Ambrosini CVV-6 Canguro.〔 It was an all-wood framed aircraft, skinned with a mixture of plywood and fabric. High mounted wings were built around single spar with a ply covered D-box leading edge. Behind the spar the wings were largely fabric covered apart from an inboard section containing the CVV-type airbrakes which extended above and below the wing, where the ply skin reached aft to the trailing edge. There was also extra ply skinning inboard of the airbrakes, forward of the oblique, internal drag strut. Outboard of the airbrakes Frise ailerons formed the trailing edge out to rounded tips. In plan the wings were straight tapered, mostly on the trailing edge; they had 8.2° of washout and each could be detached separately for transport.〔〔〔 The oval section monocoque fuselage of the Canguro was entirely ply skinned as was the tailplane, mounted on top of the fuselage, and the narrow fin behind it. The rear control surfaces were fabric covered, with a wide chord, rounded rudder extending to the keel and moving in an elevator cut-out. The crew were seated in tandem in a cabin with a wrap-around windscreen and two rectangular windows on each side. The rear seat was under the wing, with entry from above via a hatch provided with transparencies to give some upward view.〔 The prototype Canguro and those built entirely post-war had a rubber sprung skid for landing, which extended aft beyond the cabin; a drop away wheeled dolly was used for take-off. Those originally intended for the I.A.F. had a fixed wheel at the rear of a shorter skid, though this proved too small.〔〔〔 One Canguro was modified to fly under power by Adriano Mantelli. His first version, flown in 1955 had a 16.4 kW (22 hp) motor mounted on a pylon above the wing.〔〔 After storm damage this airframe was modified again〔 to take a 1.47 kN (331 lbf) Turbomeca Palas turbojet in place of the rear seat, with a ventral fuselage exhaust below the wing trailing edge. Dating from 1962, it was known as the Canguro Palas. In 1964 Mantelli set a new FAI record for C1b class aircraft of 9,700 m (31,824 ft).〔 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「CVV-6 Canguro」の詳細全文を読む スポンサード リンク
