344 FLIGHT, 15 September 1949 The 600-m.p.h. Hawker N.7/46, presented by Neville Duke. John DerryshowshowtheVenom'soutlinediffersfromtheVampire's. THE FARNBOROUGH STORY... for auxiliary fuel tanks to be mounted near the junctions of the mainplanes with the wing-root intakes for the Rolls- Royce Nene turbojet. HAWKER P. 1052.—Confirmation was to be had that the fuel tankage of this research fighter is the same as that of its predecessors, the P. 1040 and N.7/46; that is to say, there are tanks immediately behind the cockpit, in the region of the jet-pipe bifurcation, and between the twin tail pipes. Thus, as the Hawker Company are not slow to point out, an abnormally long range is reconciled with extreme speed and notable climb performance, admirably illustrated by Trevor Wade's demonstration. On Wednes- day this opened with a steep, protracted zoom in the in- verted position, followed by what can truly be described as a breathtaking plunge through dense cloud towards the airfield—which, from the zenith of the zoom, must have appeared very much contracted. The P. 1052, in its latest Cellon finish, looked the acme of fighter efficiency. Wade's low rolls were much appreciated. HAWKER SEA FURY F.B.II. Despite jet pre-eminence, no apology was needed, or made, for the presence of one of these sturdy Centaurus-powered fighter bombers. Under economical cruising conditions, with two 90-gall drop tanks, the range is more than 2,000 miles. VICKERS-SUPERMARINE ATTACKER.—Though outstripped in performance by the " 510," its lineal descendant, a stan- dard Naval Attacker was flown by Mr. Colquhoun in thoroughly reassuring style. Colquhoun's specialities were successive rolls to port and starboard. Finished in the standard Naval colour scheme, the Attacker, when air- borne, was indistinguishable from sleek models on the Vickers-Supermarine stand. The keener-eyed observers saw the lift-spoilers, forward of the flaps, in operation during the final approach and landing. VICKERS-SUPERMARINE 510.—'What was probably the fastest flying yet seen in Great Britain was only part of Michael Lithgow's offering in the Type 510 research fighter. Precise performance figures, in so far as they are known at this early stage of development, are not to be divulged, but more than one of our guests from abroad, with an eye for a fast aircraft, estimated the speed of the " 510 " on one of its low runs as over 1,050 km/hr (about 660 m.p.h.). Almost equally amazing was the rate of xoll at very high speeds—of the order of 160-180 deg/sec. This is made possible by the Automotive Products Servodyne power-assisted ailerons, in conjunction with spring tabs. With its ample wing area and relatively low weight (due in part to the normal tailwheel undercarriage), the " 510 " is reputed to handle extremely well at altitude. Reference was made in our preceding issue to the new "needle" The rakish Supermarine 510 passes by at 600-650 m.p.h Wares dispensed by the Sea Fury are conveniently displayed.
