205 Bloodhound on a lead: Bristol's 192 helicopter making off with the R.A.F.'s surface-to-air missile and trolley Fairey Rotodyne (XE 521) With 100 hr of flight developmentbehind it, the Napier Eland-powered prototype ot the Rotodyne is the test vehicle for the bigger Rolls-Royce Tyne-powered produc-tion aircraft whose future was assured on the eve of the Show by a Ministry of Supply development contract. This opens theway for completion of B.E.A.'s provisional order for six plus, an option on 14, New York Airways' order for a similar number,and other intentions-to-purchase (including a sizable order for the Army) which have been dependant upon the successfulfinancing of the development programme. It can be taken that the M.o.S. contract is of the order of £4-5 million, with Faireycontributing a similar amount. The Napier-powered prototype is fitted out for the first timewith a commercial airline interior: the rear half of the fuselage has four-abreast seating for 18 passengers, trim being in blue andgrey, and accommodation for baggage (in tiers of deep shelves at the aft end) and a washroom.The forward half of the fuselage contains test instrumentation, mainly with reference to the powerplant; the present programmeis devoted largely to vibration; a big improvement in this respect was achieved earlier in the year by reducing from 5 deg to 0 degthe incidence of the fixed wing, with consequent reduction of rotor blade flapping angles. Folland Gnat F.I (XN 326) Ordered to replace one of the original M.o.S. batch of six, this is a true production F.I and has been used for extensive armament trials with the two fixed Aden guns and under-wing stores. Folland Gnat Trainer (XM 691) Particular significanceattaches to the appearance of this prototype at Farnborough as it is understood that a substantial production order is imminent. Asis well known, the Trainer has an F.I rear fuselage—housing a trainer version of the Bristol Siddeley Orpheus—and a tandemtwo-seat cockpit in the nose. An entirely new wing of greater area with seven per cent t/c ratio has integral tankage, outboardailerons and inboard split flaps. The rear cockpit of the trainer prototype at present housesinstrumentation, but a fully equipped forward fuselage is on the Folland exhibition stand. The instructor is protected from airblast after canopy jettisoning by an extensive curved windshield and metal coaming, and the clam-shell canopy is a single plasticmoulding. Smiths Flight System instrumentation is included and controls are neatly grouped. The prototype is silver, with fluores-cent red stripes on fuselage and wings. Gloster Javelin FAW.8 (XJ 125) Standard armament of thismark (and all marks subsequent to and including the FAW.7) is four Firestreaks and two Aden guns. A further two Aden gunscan be installed in existing bays if the Firestreaks are not carried. The FAW.8 itself is distinguished by a deeper nose radome hous-ing an unidentified A.I. radar; and the Bristol Siddeley Sapphire engines have a small afterburner close against the turbine disc. The FAW.9 is in effect an FAW.7 modified to FAW.8 standard.None of the marks up to the FAW.6 can carry missiles and they differ from each other principally in the type of A.I. radar and fuelcapacity. All marks can carry two 250-gal ventral tanks. A pitch stabilizer acting on the ailerons is a feature of the FAW.8—inaddition to the yaw stabilizer already fitted in the rudder circuit. Handley Page Dart Herald (G-AODF) The Dart Herald dis-played is the second such Herald, and is the aircraft which recently returned from its 160 hr, 34,000 mile tour of LatinAmerica. Whilst it was abroad it was announced that B.E.A. would operate three on loan from the Ministry of Supply on do-mestic Scottish routes, and immediately on its return the aircraft was re-painted in the eye-catching new red wing colour scheme ofthe Corporation. (Tailplane and rudder differ in one respect from this, being painted black.) Weight data stencilled on the rear fuse-lage applied to the Comet 4B and Vanguard in the display; the rudder indicates that this Herald has been operating at 41,000 lb,2,000 lb more than the 39,000 lb for which approval was recently obtained. The interior is not trimmed according to B.E.A.'s re-quirements but is the standard 38-seater which Handley Page have been demonstrating to customers. Maximum seating is 47. The third Dart Herald is due to fly in November, and will joinG-AODF in demonstrations (the next is due to be in Australasia). Detailed components are already in the jigs for ten Dan Heralds,and a one-year delivery can be offered to customers. Hawker Hunter FGA.9 (XG 135) Basically a conversion ofthe F.6 designed for ground-attack duties abroad, this new mark is powered by a Rolls-Royce Avon 207 of slightly increased thrustand has a drag-chute, boosted air-conditioning, greater oxygen supply and cut-away flaps to accommodate the very big Hawkermild steel 230 gal drop-tanks. The latter contain float-operated fuel-contents counters which are visible from the cockpit; andelectronic gauges will be added. The drag-chute has a diameter of 13ft 6in. With 2 X 230 gal tanks and 2 X 100 gal tanks theFGA.9 has been flown non-stop from Dunsfold to El Adem, 1,800 miles, in 31 hr. Hawker Hunter Two-seater (XJ 615) Borrowed from E.T.P.S.for the duration of the display, this red and white aircraft is actually the first Hunter two-seater prototype with an Avon100-series engine and is normally used for demonstrating spinning tests. In the static park it is supported on jacks with undercarriageretracted and surrounded by its gamut of stores. Hawker Hunter Two-seater Mk 66A (G-APUX) Powered bya Rolls-Royce Avon 203 engine, this variant is in most respects identical with the Mk 66 trainer supplied to the Indian Air Force.Two Aden guns are mounted in bulges beneath the cockpit with a removable ammunition pack between them. A 10ft 6in-diameterribbon drag-chute is standard, but an entirely new feature is a Dunlop brake, with Maxaret, on the nosewheel. The additionalbrake considerably shortens the landing run and allows full engine
