29 August 1952 251 research and development Xomad—Lincoln THIS flying test-bed —one of a large number now flying in Great Britain—would hardly be favoured in a concours d'elegance; but, like its fellows, it is paying for its keep by providing invaluable operational data on a new type of power plant. The Lincoln and Lancaster World War I bomber airframes have proved amazingly adaptable not only for turbojet installations (on the wings, under, or in, the bomb bay, or in the extreme tail) but for turboprops also—either wing-mounted, or, as in the instance of the Nomad-Lincoln, in the fuselage nose. Ml am ha IA dder—Lancaster UNIQUE among the aircraft of the world in having a turboprop in the nose, four piston engines on the wings, and a turbojet in the tail, is this Armstrong Siddeley test bed. It will be seen from the photo graph that a framework has been built around the nose portion. This is an anti-icing test rig and is used in conjunction with a special ultra-coarse- pitch cropped airscrew to absorb the power of the Mamba. The Adder, the intake for which can be seen on top of the rear portion of the fuselage, has experimental afterburning equipment. Hawker i*.H)72 FIRST shown in public at last year's Display, the P. 1072 is a development of the P. 1040 airframe embodying an Armstrong Siddeley Snarler liquid-fuel "hot" rocket motor of some 2,000-lb thrust in the tail of the fuselage. Tests are now concluded and were, in any case, of a preliminary nature because the airframe was not designed for flight at the speeds and heights foreseen for rocket-powered fighters. Olympus—Canherra THREE Eng lish Electric Canberras, adapted for development flying with new types of turbojet, are due to show their paces next week. One is powered with two Armstrong Siddeley Sapphires, the second with Rolls-Royce Avons fitted with afterburners, and the third— shown here—with a pair of "two-spool" Bristol Olympus. Supermarine 510 THIS research aircraft is, in effect, a swept-wing development of the Attacker, and retains the tail-down undercarriage of that type. After many months of testing from land bases it was equipped with an arrester hook and flown from, and landed on, the deck of an aircraft carrier, being the first swept-wing machine to accomplish this. Hawker P.I052 THIS swept-wing re search aircraft was the second of its class to be operated from a British carrier. For this purpose, of course, it had special naval equipment which was not installed on the original machine. In the Hawker line the P. 1052 followed the straight-wing P. 1040 (fore runner of the Sea Hawk) and was succeeded by the "all-swept" P. 1081 and P. 1067 (Hunter).
