PLIGHT, 2 September 1960 341 BAC-107 HUNTING AIRCRAFT LTD Luton Airport, Luton, Beds. Telephone: Luton 6060 BAC-107 This small jet airliner project, which fits into the Viscount-replacement category, was conceived some three years ago by Hunting Aircraft as the H-107. A mock-up was built and design work and a market survey were carried out. When Hunting Aircraft was merged into the British Aircraft Corporation earlier this year the 107 programme gained impetus, and it is believed that Vickers have been working in dose partnership with Hunting in its design development. Now designated BAC-107, it has changed somewhat as the result of this joint study. One external change is the elevation of the tailplane-'to the top of the fin, and there are more cabin windows (26 per side). The powerplant comprises two BS.75s of 7,3501b thrust each, conferring the economy that is a dominating design requirement; it is said that the 107 uses fewer gallons per mile than the Viscount that it is intended to replace. Gross weight is put at 50,0001b. Maximum seating in a Viscount-width fuselage is 59, and cruising speed is in the 500 m.p.h. bracket. Field length is 5,000ft. Full-payload range capability with fuel reserves is of the order of 800 miles, and for maximum range a tankage of 2,230 Imp gal is available. The BAC-107 becomes the smallest member of the Vickcrs family of rear-engined jet transports, the others being the VC11 project, the VC10 and the Super VC10. It could be ready for service in 1964/1965. Following delivery of Mk 1 aircraft in 1957, the new basic trainer for the RAF, the Jet Provost T.3, has now been in production for some time, and No 2 FTS at Syerston is fully equipped. Central Flying School and the RAF College, Cranwell, also have them, and the first order for a dozen armed Jet Provost Mk 51s for Ceylon has been completed. The T.3 is powered by a Bristol Siddeley Viper ASV.8 giving 1,7501b thrust, and a number of T.4s, a later version powered by the Viper ASV.ll giving 2,5001b thrust, are also to be delivered to the RAF. A number of new features are introduced for the first time into a basic trainer, including Martin-Baker Mk 4 lightweight ejection seats for instructor and pupil, oxygen equipment, UHF instead of VHF radio, and Rebecca Mk 8 DME. Trie Jet Provost has a gross weight of 7,2001b, maximum speed of 326 m.p.h. and a ceiling of 33,000ft, and can be used to train pilots from ab initio stage to the point at which they convert to Vampire Trainers. The armed version carries two 0.303in machine guns in the intake fairings and four underwing pylons to accommodate a variety of bombs and rockets. Jet-flap Project It has been stated that Hunting are preparing under MoA contract an aircraft intended for research into the jet-flap principle, as evolved and explored by the National Gas Turbine Establishment. No details about this aircraft have been released by the company. Hunting Jet Prmoit T3 (at take-off)
