Canadair Orenda-Sabre. Speaking in New York recently, Air Marshal J. L. Plant R.C.A.F. said that the Orenda made the Sabre 5 "the best Sabre in the world". Although it was not quite as fast as the F-100, it had no equal as a day intercepter at high levels and was better than American Sabres; The Avon Sabre was not mentioned. U.S.A. Lightweight Fighter^/" With a view to future procurement" the U.S.A.F. will evaluate four new "lightweight" fighter proposals next month. They are the Lock heed XF-104, ;f*Corthrop Fang, North American Gupp"y, and a Republic project. Bell X-2. The second example of this swept-wing, stainless-steel,' supersonic re search aircraft has already been fitted with its Curtiss-Wright, rocket, of 12,000 lb thrust, and is befhg prepared for test at Bell's Wheatfieta, New York, factory. The first specimen was destroyed when it exploded while being carried by a B-29. Douglas DC-1C. Fifteen^ of these de veloped DC-7Bs are thp'subject of a $33 million order from IJjrfi American World Airways. The spaaf at 127ft 6in, is 10ft greater than thatjw the -7 and 7B, and the fin and rudderkave been heightened about 2ft. The enames will be the BA-4 model of the Wrigfit R-3350 Turbo-Compound, providing a power increase of about 20 per cent, and the inboard units will be 5ft MIDGET BOMBER: An informative view of the Douglas A4D Skyhawk carrier-borne attack aircraft, powered by a Wright ]65. Note the subtle shaping of the intakes and the pilot's good field of view over the nose. further out from the fuselage, allowing a 70in clearance between the airscrew tips and the fuselage side. Thjfi is expected to result in a noise level ofj^b order of that in the DC-6B. (The DCyf has been criticized on the score of cabin noise.) Fuel capacity will be increased/from 6,400 U.S. gallons in die DC-7Bjte 7,860 U.S. gallons, giving a range of over 5,000 miles, with a reserve of 1,200 gallons. For that range up to 50 passengers will be carried, in addition to baggage, cargo and mail. Take-off and landing weights are 140,000 lb and 107,000 lb respectively. Rocket-propelled Helicopters. Two new types of single-seat, rocket-propelled heli copters have recently flown. They are the Rotor-Craft RH-1 Pinwheel and the Kel- lett KH-15, nicknamed S»ble Mabel. The first tethered flight of the RH-1 was made last year. It has a fojttr-point fixed under carriage and Reaetii^n Motors, Inc. rocket units of about 16 lb thrust apiece at the rotor tips. The*fc.H-15 likewise has Re action Motors jackets (hydrogen peroxide), and a conventional, variable-pitch, tail rotor for directional control. The designs of these new helicopters were initiated by the Office oFNaval Research and continued under fte sponsorship of the Bureau of Aeronautics. The Transportation Corps of the U.S. Army were also concerned in the Rotor-Craft project. France Sipa 200 Minijet. An Argentine pilot of the Saptalan company has spent several days in France studying this light jet- propelled two-seater. After making six flights—two of them solo—he placed an order for one machine, to be delivered to Argentina, with. Spares, during September. Acceptance flights of this aircraft will begin early in August, and thereafter a "pre- series" of five Minijets—for unspecified customers—will be completed at the rate of one a month.
