264 FLIGHT, 5 March 195 AIRCRAFT INTELLIGENCE ACCESSIBLE AUSSIE: Now in production by the Commonwealth Aircraft Corporation is the Winjeel, the R.A.A.F.'s new basic trainer. This photograph, recently published in the Australian journal "Aircraft," shows the petal-cowled Wasp Junior to advantage. A comparison with the Provost would be interesting. Great Britain Vickers-Armstrongs 1000. Various types of "1000-series" aircraft are now being considered with both by-pass (Conway) and pure-jet engines. The first prototype, which appears likely to be Avon-powered, is now beginning to look like a complete aeroplane; it is expected to fly in the first half of 1955, and should be at that year's S.B.A.C. show. It gives promise of being a most useful aircraft, and there is every possibility of its selection as a standard high-capacity transport for R.A.F. Trans port Command. A fact not previously mentioned is that, if angle of sweepback is any criterion, the 1000 series are designed for a much higher cruising Mach number than is the smaller Valiant. Canada Canadair Britannia. The engineering department of Canadair are now hard at work modifying the basic Bristol Britannia for the R.C.A.F. as a maritime recon naissance aircraft. To some degree the M.R. Britannia should correspond with the British "stretched" series 200, 250 and 300, particularly as regards fuselage length. But the Canadair machine will be of quite different shape, and will have a longer nose and increased all-up weight. The British Messier bogie landing gear should be quite capable of use with a Britannia as heavy as 170,000 lb, with slight modification. Although the M.R. machine is designed for medium- and low-level operation, and has Turbo Com pound engines for this purpose, it is likely to be pressurized throughout. This will make it difficult to incorporate a large internal weapons bay, although such a feature has been suggested. It has been stated that the specified armament includes fixed guns and torpedoes, the latter pre sumably being of the anti-submarine homing variety. N.R.C. Meteor. A Gloster Meteor is, according to a correspondent, now being assembled by an R.C.A.F. repair crew at the flight research section of the National Aeronautical Establishment at Uplands, Ottawa. It is reported to be on loan from the M.o.S. to the Canadian National Research Council to assist in testing a reheat system developed by the N.R.C. The Rolls-Royce Derwents are retained. United States Cessna Helicopter. Last year the Cessna Aircraft Company formed a helicopter division, the nucleus of which was no doubt provided by the helicopter-designing firm of Siebel, which was taken over by Cessna at that time. Siebel had developed an experimental machine styled S-4A Sky Hawk, which had been awarded the U.S.A.F. pre-production contract under the designation YH-24. Cessna now state that their helicopter division has developed an entirely new 2-4 seat, all-metal heli copter, for which details will be available in the summer. France S.E. Sea Venom (Aquilori). For seven years past the South-East group of the French nationalized industry has been producing fighters of basic de Havilland design. First came the Vampire, in various forms; it was followed by a developed model powered by a Hispano Nene and known as the Mistrale. Now the last Mistrale has been delivered, on schedule, and its place is being taken at Marignane by the Sea Venom. S.E. are now in full production with a machine very similar to our Sea Venom F(AW)20; in France it is known as the Aquilon (North Wind) and it is powered by a Fiat-built Ghost 48. S.N.CA.S.O. Fighter Prototypes. All the flying so far completed on the first and (ill-fated) second S.O.9000 Tridents has been on the power of wing-tip turbojets. The design main power unit, a three- cylinder S.E.P.R. liquid-fuel rocket is now almost ready for installation. With the rocket fitted (in the tail) the Trident should be easily supersonic on the level at high altitude. Test pilot Charles Goujon is taking the first Trident through a special series of trials in preparation for the rocket flying. At the same time, a four- year-old S.O.6020 prototype (Espadon) has been equipped with two Turbomeca Marbore turbojets with afterburners, one at each wing tip. The basic Marbore gives about 880 lb thrust, so the revised Espadon test-bed should obtain about 2,200 lb thrust from the added wing-tip units. It was, incidentally, on an Espadon-type machine, an S.O.6026, that the Trident's rocket was tested, in single-barrel form. LOCKHEED L-1049C SUPER CONSTELLATION (Four 3,150 h.p.
