FLIGHT, 15 May 1953 T AIRCRAFT INTELLIGENCE BUILT FOR ECONOMY: The Hurel-Dubois HD-31 transport (top) is reported to be behaving well on its trials and to bear out its designer's confidence in its money-making ability. Seen in s'.de view is the first Fletcher FD-25 Defender light ground-attack aircraft assembled by the Toyo Aircraft Manufacturing Company in Japan. Great Britain Modified D. H. Vampire. To assist the conversion of R.A.F. Transport Command ferry pilots on to Canadair-built North American Sabres, a de Havilland Vampire is being fitted in Canada with an American instrument panel. The Sabres, incidentally, are arriving in impressive quantities. They are camouflaged in Great Britain. U.S.A. Republic Executive Aircraft. The execu tive aircraft par excellence is projected by Republic. It would sell for under a million 605 dollars and would be powered either with Wright J65 (Armstrong Siddeley Sapphire) or General Electric J47 turbojets. Pres surized for operation at 45,000ft, it would carry 16 passengers. New Fighters. Now under intensive development by Lockheed are a "light fighter" and at least one delta-wing air craft. One of these types—both may be the same project—has been allotted the U.S.A.F. number F-104. At the Republic plant, work is progressing on the F-103 delta fighter and the F-105 fighter/bomber, both of which owe something to the XF-91 Thundercepter. All these designs are for supersonic aircraft. Grumman S2F-1. As yet unnamed, this twin-piston-engined search and strike air craft is in full production at the Grumman Bethpage factory and may still be built at the Arlington factory of General Motors. The large search radar scanner will be housed in a "Guppy" radome under the forward fuselage. Folding wings and arrester hook are provided. Although not fitted to present production aircraft, boun dary-layer control by means of porous suction wing panels was experimented with on the S2F; with full suction-power in use it was estimated that 600 gallons of addi tional fuel could be carried, so giving 75 per cent more range. But this report does not state where the suction power was to be obtained; in any case, it is unusual for a small twin-engined aircraft to show a gain in lift of nearly 5,000 lb by this method, which is more usually a means for reducing drag. France S.N.C.A.S.E. 210. France's promising jet airliner is the joint undertaking of the S.E. and S.O. groups, as mentioned by the presidents of both groups on page 280 of our March 6th issue. Now named Cara- velle (a species of 16th-century sailing ship) the design resembles a Comet with a wing of higher aspect-ratio set well back towards the tail. Power is to come from two Atar or Avon turbojets mounted on short stalks on each side of the rear fuselage. The chosen window-shape appears to be a triangle with rounded corners, one side lying horizontally at the bottom. The wing of the prototype is being developed by the S.O. group; the fuselage is already being built by S.E. at Toulouse, where two prototypes will be assembled next year.
