20 June 1958 855 all-weather fighter, a bomber and a tactical-support aircraft. It has aswept wing carrying two SNECMA Atar 101E3 engines in under- slung nacelles. Two main undercarriage units are housed fore and aftof a weapons bay in the fuselage and supported by outriggers retracting into the engine-nacelle flanks. A braking parachute is fitted. The bomber version carries a single pilot and a bomb-aimer in atransparent nose compartment. Bombs are attached to a rotating plat- form in the bomb-bay and other stores can be carried under the wings.There is no defensive armament. The tactical-support version is a single-seater carrying four 30 mmcannon in a gun-pack in the forward fuselage and a variety of stores under the outer wings in addition to a rotating bomb-platform. Packsof up to 240 rockets may be carried in the bomb-bay or these may be replaced by a B.I0 guided air-to-ground weapon. All three versions of the Vautour can exceed Mach 1 in a dive andhave considerable range and ceiling. Span, 49ft 6iin; length, 51/t lin; max. speed, Mach 0.9 at sea leveland 595 m.p.h. at 40,000ft; service ceiling, 44,000/t; time to 39,370/*, 4 min 49 sec; ferrying range, 3,700 miles. ANTI-SUBMARINE Breguet 1050 Alize A carrier-based anti-submarine search and strikeaircraft carrying a crew of three, search radar, sonobuoys, weapons and powered by a Rolls-Royce Dart RDa.7. An order for 75 has been placedand construction is well under way. The radome retracts into the rear fuselage, and the main units of the nosewheel undercarriage retract intopods on the wings which also accommodate equipment. Flare- and buoy- chutes are located in the fuselage flanks, just aft of the cabin section. Span, 50ft lin; length, 45ft; gross weight, 17,640 Ib; endurance over4 hr; max. range 1,550 miles; patrol speed, between 140 and 205 m.p.h. Breguet 1050 Alize TRANSPORTS Breguet 76S Sahara The military version of the Breguet Deux Ponts,which has seen extensive civil service during past years. Certain modifi- cations are incorporated to suit the machine for military cargo carryingand P. and W. R-2800-CB-16 or CB-17 engines are fitted. Trials have established ability to parachute heavy loads. One hundred and fifty para-troops have been dropped, a fully equipped battery of 105 mm guns carried, or an AMX medium tank. Span, 140/1 5in; length, 94ft llm; empty weight, 68,343 Ib; max.gross weight, 119,050 Ib; take-off to 50/f, 5,100/t; range, with allowances, using tip-tanks, 2,930 miles. Breguet Integral The aerodynamic test version for this STOL trans-port has now flown and development of a rather larger military version is under way. Lift is obtained for near-vertical take-off by bathing thewhole wing in the slipstream from four large propellers coupled to a transverse transmission shaft. The slipstream is also deflected verticallydownwards by large double-slotted flaps and drooping double-slotted ailerons. The elevator, too, is double-slotted, and droops in unison withthe flaps. Four Turbomeca Turmos, giving 450 h.p. each, drive through their free turbines into the transverse transmission, so that failure of oneengine will not cause one propeller to stop rotating. A crew of two sit side-by-side in a fully glazed nose compartment, ahead of a large cargohold having rear-loading doors. The undercarriage of the military version will probably retract into bulges alongside the fuselage. Versionsare foreseen with either General Electric T58s or Lycoming T53s. GENERAL PURPOSE, LIAISON AND SPOTTING Max Holste MH.1S21 Broussard Designed originally as a privateventure, the Broussard was adopted by the French forces and 350 of them have been ordered for utility and command liaison work. Possibleloads include army radio, cameras, stretchers, passengers or cargo. The high-set, rigidly braced, all-metal, torsion box wing carries slotted flaps,slats and ailerons, the latter arranged to droop to 13 deg when flaps are lowered to 45 deg. Twin fins and rudders are fitted; and the under-carriage legs are spring steel units made under Cessna licence. Power is by Pratt and Whitney R-985, giving 450 h.p., with a Hamilton Standardpropeller. A handling report appeared in Flight for March 23, 1956. Span, 45ft lin; length, 28/t lin; empty weight, 3,256 Ib; gross weight,5,500 Ib; max. speed, 168 m.p.h.; econ. cruising speed, 143 m.p.h.; minimum speed, 53 nup.h.; take-off to 50/f, 1,066/f; service ceiling,19,030/r; max. range, 745 miles. Max Holste MH.2S0 Super Broussard A military order has beenplaced for a number of prototypes of this twin-engined, short-field transport. Mock-ups of the cabin section were shown at the Paris showlast year. Capable of carrying 17-20 passengers or 4,122 lb of freight and having rear-loading doors, it will be an all-metal, high-wing mono-plane powered initially by two P. and W. R-1340s giving 600 h.p. each and later by two Turbom6ca Bastans of 650 h.p. each. High-lift devicesincluding full-span slats are incorporated to ensure excellent short-field performance. A semi-retractable nosewheel undercarriage, the mainbogies of which retract partially into fuselage bulges, is to be fitted. Span, 70ft lin; length, 51/t 10in; empty weight, 8,850 Ib; gross weight,14,603 Ib; max. speed, 115 m.p.h.; econ. cruising speed at 9,000/f, 174 m.p.h.; stalling speed, 63 m.p.h.; take-off to 50ft, 1,050/t; normalrange with reserves, 603 miles.
