24 FLIGHT. JANUARY 3, 1935. Commercial Aviation HESTON A " Centenary " ; Indian National Airways1 Duplication : Jersey Traffic T HE agricultural season has arrived. The season, that is, when persistent downpours have softened, and tail- skids have damaged, the surface at Heston, and when portions of it are ploughed and resown in preparation for the summer. A hundred years ago, almost to the day, 320 acres of Heston, including the present landing area and the neighbouring land reserved for expansion, were ploughed in one seven-hour working day! One thousand and fifty horses and twenty yoke of oxen were employed in this gigantic enterprise, which provides the only centenary which Heston can honestly claim. Airwork's associated company, Indian National Airways, will, during this year, run twice-weekly passenger and mail services between Calcutta and Rangoon, in place of their present weekly service. Their second service is scheduled to connect with the duplicated Imperial Airways service from London to Calcutta. The second of Imperial Airways weekly services runs through to Australia, calling at Rangoon. The duplicated service, however, leaving London on Tuesdays, terminates at Calcutta on the following Monday, and pas sengers and mails on this service may proceed to Rangoon on the following day by Indian National Airways. The return service of Indian National Airways from Rangoon will con nect with the Imperial Airways service, which leaves Calcutta on Saturdays and reaches London the following Friday. In this way passengers will be able to travel twice weekly between London and Rangoon, and mail addressed to Rangoon will be delivered by air without extra charge. One of the "regulars" on the Heston to Jersey route is Colonel Hinde, whose wife and child, with a nurse, made the journey for the first time by air when they travelled out to join him on Boxing Day. In the week ending December 27, forty-four passengers travelled by Jersey Airways from Heston to Jersey and fifty- eight passengers in the reverse direction. Since the New Year the hire business which operated under the name of Wrightson Air Hire. Ltd., has been working under the altered name of Air Hire, Ltd. The Directors of the new company are Mr. R. G. Wrightson, Mr. A. G. Douglas, and Mr. C. Wrightson. FOR AIR FRANCE The Dewoitine cc Antares" to be put on the Far Eastern Service this year A Development of the Ill-fated " Emeraude" The new Dewoitine, a development of which may be used on the Channel services this year. THE first of the new Dewoitine three-engined low canti lever wing monoplanes, which have been ordered by Air France for operation on its Far Eastern* and other long distance routes, has been completed and will shortly begin its trial flights. This machine, known as the " Antares," or 333, is similar in design to the ill-fated "Emeraude," but has been largely strengthened throughout. It now has a load factor of seven, an increase of two on that required by the C.I.N.A. The "Antares" is constructed of metal throughout, and is designed to carry eight passengers, who will be seated in large reclining chairs which can be used for sleeping. There are also two large holds in which postal matter, baggage or freight can be carried. The centre section, in which are located three tanks with a total capacity of 712 gallons, is built into, and forms part of, the fuselage. On each side of this three lateral panels are joined, and the wing structure itself consists of a main spar located about a third of the chord from the leading edge and of two intermediate spars placed at the rear end of the fuel tanks, which are installed behind the engine mountings. The spars, together with the ribs, are constructed of duralumin, and a smooth Vedal sheet metal stress-carrying covering com pletes the structure, which has a box form, on each side of the centre spar. The fuel tanks, incidentally, are equipped with independently operated dumping devices, and oil tanks, of 18.7 gallons capacity each, are installed behind the engine. The engine mountings are of chrome-nickel steel tubing reinforced by steel ribs. Of monocoque construction, the fuselage is also covered with Vedal sheet, and the structure is composed of bulkhead frames and intermediate formers connected by four main spars and reinforced by stringers, all of which are made of duralumin. It is divided into three sections. The forward part contains an enclosed pilot's compartment with two side-by-side seats equipped with dual controls. The radio operator is located behind, and a baggage hold of 24.7 cu. ft. capacity is located underneath the central oil tank. The central portion contains the cabin, which is 19.7 ft. long, 5 ft. wide and 5.7 ft. high. Behind the cabin is a lavatory. The after portion of the fuselage contains a second hold of 70 cu. ft. capacity. The empennage is likewise of metal and is composed of spars and ribs of duralumin covered with Vedal sheet. The tail has swivel wheel attached to an oleo-pneumatic shock absorber. The cantilever undercarriage consists of two inde pendent parts, each of which is located under one of the outboard engines. Messier shock absorbers are used and the wheels are in well-faired " trousers." Three Hispano-Suiza nine-cylinder radial engines, type gV, rated at 575 h.p. each, are fitted with N.A.C.A. cowlings and two-bladed Levasseur airscrews. With these engines the maximum and cruising speeds are 187.5 arKl 160 in.p.h. res pectively, and the cruising speed at 55 per cent, of the full power is 140 m.p.h. The flight radius is 1,260 miles with normal load. These particular engines have been considerably " stepped up " recently, and it is understood that the latest types deliver something like 700 h.p., so an improvement in performance may be expected if they are fitted. Another development of the "Antares " is being constructed to carry 30 passengers, and it is possible that this D.620 type, as it is known, will be used on the cross-Channel service this year. A South Atlantic "Record" Last week's return flight of the German South Atlantic air mail service beat all records when the Heinkel used on the last leg of the route reached Frankfort-on-Main twenty-four hours before its normal schedule.
