The Leonides-powered Prestwick Pioneer has a remarkable take-off and mding performance. (Left) A pleasing study of Short's shapely Sealand flying-boat amphibian (two Gipsy Queens). PRELUDE TO PARI A. V. ROE AND CO., LTD. KNOWN to all in wartime for their Lancasters and Ansons,A. V. Roe have recently come into the limelight again with turbojet research aircraft 6f delta configuration (Avro 707) while continuing with the four-jet Ashtons for high-altitude research and maintaining the Lancaster-Lincoln line with the Shackleton, now beginning to equip the R.A.F.'s long-range coastal recon- naissance squadrons. It is learned that handling trials with the delta aircraft have been giving most promising results. The Shackleton is considerably larger than the Lancaster, and for patrols and submarine hunting—sorties of very long duration —crews need the increased space, comfort and equipment it pro- vides in order to carry out their duties with maximum efficiency. The four engines are Rolls-Royce Griffons, driving contraprops. The latest version of the perennial Anson trainer continues to give good service. Since the end of the war exports have amounted to £71 million, including spares, and the countries concerned are Afghanistan, Argentine, Australia, Belgium, Burma, Canada, Egypt, Eire, Ethiopia, France, India, Portugal, South Africa and Sweden.

THIS company can justly claim that its name has become aninternational adjective indicative of the highest quality and today its aircraft gas turbines maintain the standard of "R.-R." excel-lence. The Paris salon will have the distinction of presenting the Avon for the first time in public and with this immeasurablyimportant military (and civil) axial turbojet will be shown the Derwent and the Dart turboprop. Very-large-scale production ofAvons—for the Canberra in particular—is planned in Great Britain, and a licencing agreement has been negotiated with Aus-tralia, where Nenes are already being produced. The Avon has a specific consumption at maximum continuous power rating of0.865 lb/hr/lb. The Hispano-Suiza company, will, at Paris, show a Nene as pro-duced under licence in France. Belgium and the Argentine hold licences to build Derwents. Few direct exports have beenauthorized since the war, though some years ago (and as it has turned out, misguidedly) a government decision led to the deliveryof a number of early centrifugal units to Russia where they are believed to have been put to very good use. Most important ofthe foreign agreements is that with the Pratt and Whitney com- pany of America who are producing and developing the Tay. Address: Nightingale Road, Derby. At Paris: Stand No. 33 Grand Nef. SAUNDERS-ROE, LTD. MARINE aircraft have always been the forte of Saunders-Roe,and the company is now engaged on the construction of ten- engined Princess flying boats and the S.R/A.i twin-jet fighterflying boat. The Princess, which should begin its flight trials this The Viscount 700—most comfortable of airliners—is eaeerly awaited on European routes. Power is supplied by four Rolls-Royce£6rt turb •lilht" photofripti Saunders-Roe have taken over the development of the Skeeter Ciena VV.14) two-seater helicopter. This attractive little aircraft is in future to have a 180 h.p. Blackburn Cirrus Bombardier engine. The Slingsby 7". 34 Sky sailplane, latest of its line, an example of which is displayed in the Festival of Britain Exhibition. year, measures over 219ft in span, and will weigh about 140 tons. A still-air range of 5,500 miles and a maximum cruising speed of 380 m.p.h. are forecast. The present S.R/A.i fighter is capable of over 500 m.p.h. and has demonstrated an extraordinarily high standard of manoeuvrability. The company has lately taken over the development of Cierva helicopters, particularly the W.14 Skeeter two-seater with 180 h.p. Cirrus Bombadier engine. Address: Osborne, East Cowes, Isle of Wight. SHORT BROTHERS AND HARLAND, LTD.O F particular interest to Paris visitors is the Short Sealandflying-boat amphibian, which has now undergone extensive trials at home and overseas. Compact and attractive, it has a goodperformance on the power of two Gipsy Queen 72s. The com- pany's other activities are mainly confined to the military field nowthat the large flying boats—in particular the popular Solents—are no longer their direct concern. Sturgeon T.2 target tugs are beingdelivered in small numbers, and development of the Mamba- powered S.B.I anti-submarine aircraft continues. The name of (Concluded on page 711) Latest Westland-Sikorsky product is the S.S5, due to be demonstrated in England for the first time to-day. The engine is a Pratt and Whitney Wasp.
