The models will include the Viscount 700- pressurized, Dart-turboprop-powered airliner, which can be arranged to carry from 40 and 53 passengers; the Nene-Viking; the Vickers-Supermarine Attacker; the Valetta military transport; the somewhat similar variant for crew train- ing, which has been redesigned with a nosewheel under- carriage and underslung bomb bay, and is known as the Varsity; and the Seagull (Rolls-Royce Griffon) amphibian with variable-incidence wing. It is rumoured that if an example can be prepared in time, the swept-wing Vickers-Supermarine Attacker fighter with Nene turbojet may make its public d6but in the Orly flying demonstration programme. The same is said of the new Hawker P. 1052 which is a swept-back version of the P. 1040 and the N.7/46 Naval fighter. Safety in the air is the them"e of the Ministry of Supply display, but many activities will also be illustrated. A D.H. Ghost will be shown and early Whittle turbojets will be sent from the National Gas Turbine Establishment. The Nene Vampire and A.W.52 in model form will be indicative of the Ministry's aircraft-research activities. Among the variety of examples of work from the Examples of B.P.-type fuel booster pumps by the Self-Priming Pump Company. The largest (left) is the B.P.3 Mk. 3 (400 gall'hr. at 10 . Ib/sq in.); the smallest is the B.P. 14 Me. I (50 galljhr. at 5 Ibjsq in). instrumentation section will be an electronic rev counter for engine test-beds, a shock-wave recorder, and a model demonstrating the g effect of turns. Radio and radar will take the form of a T.R. 1501, Gee Mk 3, a radio compass and a cloud and collision warning set. Other exhibits will include a sectioned 7.2m ramjet, a model of the S.R.45 a fire prevention demonstration panel and an example of a plastic roller bearing. Quite elaborate plans have been made by the Ministry of Civil Aviation, and the centrepiece of their stand is to be a model, 10ft by 4ft, of the main runway at London Airport. It will have the new British '' line-and-bar'' approach lighting, aad runway and taxi lights. A model aircraft will be capable of making circuits under control An indication of the variety of aircraft steel castings produced by David Brown (Huddersfield), Ltd. These examples are to specifica- tions D.T.D.666/705. from a console placed in the foreground and having G.C.A. azimuth and elevation expanded position indicators ar- ranged for direct view- ing. Spectators will be able to watch the sequence of events from take-off to touch-down and to hear the in- structions given by the talk-down controller. Other displays will be concerned with air- traffic control over the British Isles and the layout and facilities at London Airport. The Corporations will be represented, with other members of I.A.T.A., by panels and their symbols, and B.E.A., as the British airline serving Euro- pean capitals, will re- ceive additional recog- nition. Chief among British aircraft firms in the ancillary field will be David Brown and Sons (Huddersfield), Ltd.. Dowty Equipment, Ltd., H. M. Hobson (Aircraft and Motor) Components, Ltd., and the Self-Priming Pump and Engineering Co., Ltd. T.K.S. (Aircraft De-icing), Ltd., had hoped to introduce their new slotted-type distributor but this equipment cannot now be finalized in time. David Brown will show aircraft steel castings—A.I.D. and A.R.B. approved—for a variety of purposes, such as wing-hinge fittings and arrester hooks, and heat- resisting alloys for gas turbines. The products of Self-Priming Pumps are familiar to industry and aircrew alike, and chief among them are the various submerged electric fuel-booster pumps. Ah example of the huge Brabazon steerable nosewheel assembly will, no doubt, be the Dowty exhibit to attract most interest. Several of the foremost British firms will be represented by companies with whom they have licensing agreements. Thus, Hispano- A model to I /24th scale of the Bristol Type 175 medium-range airliner.
