FLIGHT Short SC.S Britannic SHORT BROTHERS AND HARLAND LTD. Queen's Island, Belfast. Telephone: Belfast 58444 SC.5 Irlliwir 1 Intended for initial operation by R.A.F. Transport Command, the bigBritannic is Britain's first specialized transport aircraft for strategic, long-haul, all-freight opera- tions. It is the most capacious and, after the VCIO, the heaviest land aeroplane now buildingin this country. Powerplant will be four Rolls-Royce Tyne RTy.12 turboprops of some 5,730 ch.p. each. Delivery to the R.A.F. will be in 1964. The general layout—high wing, rear axial ramp-loading from truck-bed height—conforms to the classic concept of the all-freight transport designed for the rapid loading of bulky weapons and freight, and for the air-dropping of parachute troopsand their supplies. A typical military load could be a large radar installation, a ten-ton truck and a £-ton truck. Bigmissiles and guns could also be carried. The design field length at the maximum weight of 218,000 lb is 7,000ft, and the Britannic will be able to uplift its capacity payload of 85,000 lb overa stage distance of 1,150 statute miles at a cruising speed of 340 m.p.h., with 20 per cent fuel reserves. Alternatively, with a capacity fuel load of 81,200 lb the Britannic will be able to carrya 25,000 lb payload over 5,050 statute miles also at 340 m.p.h., and with ample fuel reserves. Total cargo volume available in the rectangular section of the pressurized fuselage exceeds10,000 cu ft, and including the rear ramp the hold is 80ft long, has a maximum height of 13ft 9in, and has a floor width of 12ft with a maximum width of 16ft lin. The big sloping ramp door at therear gives unhindered access to any load that these dimensions can contain. Short SCT Still in the project stage in Short's new Light Aircraft Division, the SC.7 is alight general-purpose freighter designed to carry a 1J ton payload—passengers or freight, including cars—off short runways. Canberra PR.9 The revised wing, with extended chord and span and powered ailerons, isnow a familiar feature of this high-altitude reconnaissance Canberra. Production aircraft now emerging from the Short factory have an offset fighter-type canopy, and the complete nose swingsopen to give the navigator access to his ejection seat. Both radar and optical scanning equipment appear to be housed in the nose cap. Very powerful Rolls-Royce Avons and the new wingundoubtedly combine to give this Canberra variant exceptional high-altitude capability, and its military equipment is most comprehensive. SCI Two examples of this jet-lift VTOL research aircraft are now flying, and the fulltranslation cycle from hovering to forward flight is imminent. Some 10 hr of hovering have been completed in and out of the gantry and several hours of horizontal flight have proved the aero-dynamic characteristics and have shown that the windmilling r.p.m. of the vertical engines can be accurately adjusted for relighting during forward flight. The SCI is a single-seat delta-wing research aircraft with a fixed nosewheel undercarriage.Lift for vertical take-off is supplied by four Rolls-Royce RB.108 turbojets mounted vertically in the centre of the fuselage. These engines can be slightly inclined for initial translation; and airbled from them is vented from adjustable nozzles at nose, tail and wing tips controlled by an autostabilization system. Conventional aerodynamic controls are also provided for forward flight.A fifth RB.108, mounted horizontally in the tail, provides power for forward flight. VTOL/STOL Fighter Revealed for the first time during the Paris Salon was a hypothetical lightweight strike fighter similar in layout to the SCI but employing eight lifting engines. Thrust for sea-level speeds up to M 0.98 would come from an afterburning turbofan engine. A one-ton weapon load could be delivered at low level over a radius of 250 miles, and the fighter would be supersonic at altitude.
