FLIGHT, 3 July 1953 side by side) through a floor hatch. The armament is two MAC 7.5-mm machine-guns with 400 rounds each, fwo Alkan bomb carriers, two Matra M.3 rocket mountings, two Type 4E gyro gunsights, and a Facine F.72A camera gun. The limiting Mach number for normal flying is quoted as 0.8 and for bombing training 0.7. The span and length, respectively, are about 31 and 32ft, and the gross weight is 5,490 lb. Morane Saulnier 733 Alcyon: The specimen on view is No. 9 of a production batch of 100 now being constructed at Tarbes. Its cowling bears the insciiption "Centie d'Experiences Aeriennes Militaires." The design dates from five years back, when the French Air Force organized a competition for two three- seat all-metal trainers. The Morane entry was the M.S.730, powered with a Mathis G8R engine of 190 h.p. and which flew in August 1949. This was followed by the M.S.731, with a 240 h.p. Salmson, and the M.S.732, likewise Salmson-powered but strictly a two-seater. The M.S.733 Aew m September, 1951 with a Potez engine, and finally was declared the winner of the competition. Nord S56A: Two examples of this air O.P. monoplane are displayed—one in the hall and one in the aircraft park. The prototype flew in March 1951, and a batch of no is on order for the French Armee de Terre. Visibility is of a quite exceptional order. Cruising speed with a Regnier engine of 135 h.p. is 105 m.p.h., minimum speed 43 m.p.h., and gross weight 1,950 lb. It is interesting to observe that a v.p. airscrew is considered worth while, although this refinement is not favoured in comparable Auster types. Nord 2501 Noratlas: The specimen statically displayed is No. 04 and is equipped for passenger work. Place-names of the extensive South American tour undertaken by this aircraft are inscribed on the fuselage. With two Bristol Hercules 739 engines, giving 2,040 h.p. for take-off, the Noratlas cruises at 210 m.p.h. Seventy-five of these machines are on order for the French Air Force and the type has also been adopted by Brazil. Gross weight is 42,990 lb. North American Sabre: A Canadian-built F-86E Sabre of the R.C.A.F. is on display. Last Sunday it ascended to 43,000ft (Top left) A.S.T. target-glider. (Above) Internal accommodation of the Potez 75. (Left) Model of the S.E. Durandal intercepter. and made a faint supersonic boom before demonstrating at lower levels. Potez 75: In the 15 days following its maiden flight this piston-engined light ground-attack aircraft made 25 flights. From a French source we learn that it can be considered as "a perfected motorized ground weapon, but cleared from road servitude and faster and more mobile than the usual rolling ones." It is mainly intended for attacking, from very low level, enemy armour which has advanced into home territory, and its main weapons will be guided missiles, aimed by an observer seated in a heavily protected nose cockpit. Of simple and sturdy construction, its flying quali ties are said to be such that the average private owner would feel quite at home. The machine has, in fact, been described as a "home guard" weapon, and the makers foresee groupes airiens de terre (ground support air formations) established at low cost. The construction is all metal, the span 43ft and the gross weight 5,290 lb. Republic F-84 Thunderjet: A standard F-84 Thunderjet of the U.S.A.F. is available for inspection. Sipa S.12: A specimen of this familiar tandem-seat trainer (No. 47) is one of a batch of 50 built for the French Air Ministry. Its predecessors were the S.10 and S.n, and of the three models a total of 231 has been ordered or delivered. The gross weight is 5,017 lb and the engine a SNECMA Argus 12S023H of 580 h.p. Sipa Trainer Project: A model shows a light trainer with tandem seats, root intakes and a jet outlet beneath the fuselage. S.E.2410 Grognard: The Grognard shown is the earlier of the two prototypes, to which reference was made last week and, having a more sharply swept wing than the S.E.2415, achieves a higher speed. Figures quoted to us were a Mach number of 0.84 and a speed of 652 m.p.h. at sea-level, and a Mach number of 0.86 and 590 m.p.h. at 29,500ft. A typical armament would be two 30-mm guns with 200 rounds each and—internally stowed on a retract able framework—40 rocket projectiles of the T.io type, or 200 of the Air-Sol 4 kg pattern. The rate of fire is said to be 1,800 a minute. It is calculated that with two Hispano-Suiza Tays the range for the ground attack mission would be 465 miles. With escort-fighter equipment and armed with two 30-mm guns with 120 rounds each, a range of 1,860 miles should be attainable. S.E.5000 Baroudeur: One learned on the S.E. stand that this unorthodox ground-attack aircraft, the first description of which appeared in the preceding issue of Flight, should fly within a few days at Istres or Marignane. The pilot will be M. Maulandi. The method of mounting the aircraft on its rocket-propelled take-off trolley was described last week, and a model in the Salon illus trates this procedure. S.E. Durandal: A model of this light, delta-wing, supersonic S.E. (de Havilland) Sea Venom, with modified tail. &£, - •;,, •. ' iSS '^rsi
