DE HAVILLAND VAMPIRE The aircraft shown in the three-view drawing is the Vampire F.B.30, which was developed and manufactured by de Havilland Aircraft Pty., Ltd., of Bankstown, New South Wales. Basically a single-seat Mk 5, the Australian variant is powered by a Nene 2-VH turbojet manufactured by Commonwealth Aircraft under licence from Rolls-Royce. This engine, which embodies numerous magnesium-alloy components to save weight, is about 50 per cent more powerful than the Goblin fitted to British Vampires, and results in a notable increase in all-round performance. To serve the double-sided com pressor an additional pair of intakes is provided on die rear fuselage decking. A total of 80 Vampire 30s has been built, and all have been confined to service within the Australian mainland. It is, with the Mustang, the standard fighter-bomber of the R.A.A.F. and Citizen Air Force—with die exception of the famous 77 Squadron, of Meteor 8s. The photograph shows die first of an initial order of 36 Vampire Trainers which are being built at Bankstown for the R.A.A.F. and Royal Australian Navy. Virtually identical widi the British Vampire T.ll and T.22, die later production Australian Vampire Trainers will have me extended dorsal fins and clear-vision canopy now standard on the type. The initial batches of diese aircraft were assembled in 1952 and early 1953 from Australian- built wings, booms and tail units, die wooden fuselage nacelles being imported from England. British-made Goblins are being used on all aircraft. AVRO CANADA CF—100 The prototype of the eventual Avro Canada CF-100 first flew at the beginning of 1950; the type has since been considerably developed. One year ago, 83 prototypes, pre-production Mk 2s and production Mk 3s had been delivered, and diese were then followed by the more powerful Mk 4, deliveries of which began last autumn, and are being maintained on schedule; already a considerable proportion of the total order of some 600 has been delivered. The Mk 4 is powered by two Avro Canada Orenda 11 turbo jets, each of some 7,500 lb thrust. The 54ft fuselage carries a radar-directed fire-control system in the nose, which is supplied as a unit by Hughes Aircraft of California. The pilot and navigator sit in tandem ejector seats in the air-conditioned and pressurized cockpit, and the centre fuselage houses a very large quantity of fuel. In the belly is a bay for a quickly removable pack containing either eight 0.5in guns and ammunition or a number of 2.75in unguided air-to-air rockets. A total of 104 other air-to-air rockets can be carried in streamlined pods at the wing-tips, as an alternative to a total of from two to 12 guided weapons, according to the type employed. This armament is the heaviest of any fighter in service. The airframe is de-iced by electric heater mats, and die engines have alcohol sprays on the intake cone "spinner." A Dowty twin-wheel undercarriage is fitted. Finally, it is noteworthy that, in spite of the CF-100's great bulk and lack of wing-sweep, the airframe is so strong and me control system so good that supersonic speed can be attained in a dive. o tr 5,000 lb-thrust CA.C.-buiU Nene *-VH Span Length Gram weight Maximum speed 38ft 31ft about 11,000 lb about 570 m.p.h.
