55» FLIGHT Britain's Turbine Aircraft . . . manufacturers have announced no details, but such a machine might be powered with four axial-flow turbojets of about 8,ooo-lb thrust and having a specific fuel consumption in the region of 0.75 lb/hr'lb thrust. It might have increased internal tankage; a lengthened fuselage accommodating about 50 passengers; and an increased all-up weight—perhaps 120,000 lb. Such a machine should be capable of carrying nearly its present capacity payload of 12,000 lb for a practical range of over 3,000 miles. Before its advent, however, the Ghost-Comet should benefit appreciably from higher thrust ratings. The significance of the fact that, other than the Comet, the Avro Canada Jetliner is the sole pure-jet transport is that the development of pure-jet aircraft of this class has been confined to the British Commonwealth, and could not possibly be extended to America or other countries for a lengthy and crucial period. The Jetliner is powered with four Rolls-Royce Derwent Vs and weighs 60,000 lb. It must The Handley Page (Reading) Mamba-Marathon, below, is a fast feederliner. Smooth, quiet and fast—the Handley Page Hermts V (four Bristol Theseus). be emphasized that this machine is a seriously intended commercial proposition and—not withstanding a certain superficial resemblance to the Avro Ashton—is not confined to research and development-flying. The Ashton is a jet conversion of a piston-engined airliner and, like certain other British jet aircraft of its class, is duly referred to under the heading "Research Aircraft." Turbine-powered commercial machines now building in Great Britain are the Bristol Brabazon II, with four Bristol Coupled Proteus, the Saunders-Roe Princess flying-boat (four Coupled Proteus and two single Proteus), and the Bristol Type 175 (four single Proteus). Saunders-Roe have a project for a high-speed flying-boat called the Duchess, with four Ghost turbojets. A striking manifestation of Britain's lead in the development of turbine-powered commercial aircraft—the first three de Havilland Comets.
