238 The German-designed, British-powered Pulqui II, 1950. 240 Australia's Pika (1950) was a piloted prototype of a pilotless target. 1950 Although the Germans had conducted a great deal of basic research into the properties of swept wings as a means of achieving higher speeds, prototypes which were to benefit were incomplete when the war ended. Professor Tank, of Focke-Wulf, was but one German technician who sought an early opportunity to emigrate, and under his direction the Nene-powered Pulqui II (238), of the Argentine Instituto Aerotecnico, was built. It is worth comparing with the Mig-15. By 1950 America's turboprop programme was slowly advanc ing, and the first large flying-boat to use these power plants was the U.S. Navy's magnificent Convair XP5Y-1 (239). Four Allison T-40 "double" units, of a nominal 5,500 h.p. each, gave a top speed of about 390 m.p.h. Two of the remaining types for 1950 are symptomatic of the increasing part played by the Commonwealth in aircraft develop ment. The Pika (240) was a piloted prototype of the Jindivik pilotless target aircraft, which flew under automatic control in 1952. Both aircraft are products of the Division of Aircraft Production of the Australian Department of Supply. The Avro Canada CF-100 (241), first flown with Rolls-Royce Avons, is a twin-jet all-weather fighter, designed with an eye to the climatic and geographic problems peculiar to Canada. A Mk 4 proto type, powered (like all production models) with Avro-Canada Orendas, achieved supersonic speed in the dive last year. The massive freighter at 242 is the Blackburn and General Aircraft G.A.L.60, the Hercules-powered prototype of the larger, heavier, Centaurus-engined Beverley now in production. The designed task of the G.A.L.60 was the transport of heavy military equipment, stores and personnel, to be landed on secondary airfields or dropped by parachute through the rear doorway. At the opposite end of the freighter scale is the unique Auster Ambulance/Freighter (245), produced by a British com pany long famed for its A.O.P., touring and training monoplanes. 1951 One of the most beautiful aircraft ever built, the Hawker P. 1067 (243) now in production as the Hunter, was designed round a Rolls-Royce Avon turbojet and an armament of four 30mm guns. It has a counterpart in the Supermarine Swift, which was developed from the straight-wing E.10/44 as was the Hunter from the P.1040. On September 7th, 1953 an Avon-powered Hunter (some production aircraft have the Arm strong Siddeley Sapphire) set up a world speed record of 727.6 m.p.h. This was soon surpassed by a Swift, which took advantage of the heat of North Africa in achieving 737.3 m.p.h. The Italian Fiat, Macchi, Piaggio and Ambrosini concerns have been noted for many years for their attractive and serviceable training aircraft. At 244 we show Italy's first jet trainer, the beautifully constructed G.80, powered with a de Havilland Goblin turbojet and capable of 550 m.p.h. The Scottish Aviation Prestwick Pioneer Mk 2 (246) is an excellent modern example of the high-lift, high-wing monoplane formula popularized by the Fieseler Storch. A five-seater, it takes off in 75 yd and lands in 66 yd. 246 The Scottish Aviation Prestwick Pioneer Mk 2 (1951). 239 The first turboprop flying-boat was the Convair XP5Y-1 of 19E0. •'••' :• ••' 'y''.'••; :f/•'-'•:¥.• -•--• ^::::';]-*-:-::- "••:.-'"- V:v::^:-V:./>•.
