382 FLIGHT LEVEL SONICS THE firm of Avions Marcel Dassault seem to haveprofited greatly from the work done by North Ameri- can Aviation in developing the F-86 and F-100. As each new Sabre was announced its principal features were rapidly incorporated—to very good effect—in the French company's Ouragan/Mystere line. Latest of this line is the Super Mystere, otherwise the Mystere IV B.I; and, although it is scarcely the equal of the Super Sabre, it is certainly among the fastest fighters in Europe. Compared with its forerunner it has wings and tail surfaces with slightly greater chord and sweep angle, a flattened oval nose intake, a Hunter-like cockpit canopy affording better visibility and a powered "slab" tailplane. The latter feature, in particular, is stated to have effected a marked improvement in transonic handling. The engine is the Rolls-Royce Avon RA.7R, giving about 9,500 lb thrust with afterburner, for which Hispano Suiza hold a manufacturing licence. The Super Mystere first flew at Melun Villaroche on March 2nd, in the hands of Cmdt. Boudier. In its first three days of flying, the aircraft exceeded Mach 1 four times in level flight and 10 times in shallow dives. The transonic flying took place at 9,200m (30,000ft), which height was reached in 2 min 30 seconds. Having completed Dassault testing, the Super Mystere is now being put through C.E.V. trials; Cmdt. Carpentier, of this establishment, has flown it beyond Mach 1 on many occasions, at altitudes of about 16,000m (52,500ft). The S.N.CA.N. (ex-S.F.E.C.M.A.S.) 1402 Gerfaut IB, also illustrated on this page, exceeding Mach 1 in level flight, without power boosting, on February 11th. Compared with the first version of the Gerfaut, it has a new wing, extending farther forward and farther aft, and possibly with a greater thickness/chord ratio. The Dassault Mystere IV B.I (top right) is discussed above. Below it is the SFECMAS Gerfaut IB which, on the thrust of an Atar 101C, is likewise sonic on the level. PAPERS ON PLASTICS T\ETAILS have recently been issued of the papers to be read U at the British Plastics Convention, to be held in conjunction with the British Plastics Exhibition at Olympia, London, from June 1st to 11th. Virtually all the papers, it will be seen, will be of interest to those concerned with the design or production of plastics details for the aircraft industry, and a few are of direct interest to designers of major components.
