18 FLIGHT, 14 August 1959 »• UtK tMHMMIMM fftEMIMTINE 12 «U 21 JII« 1?5t JEHMIT II ItltlfT The 23rd Paris Show AIRCRAFT, MISSILES, ENGINES Aerfer Ae 150 A model showed the Ae 150 to be a high-wingSTOL transport project powered by twin Rolls-Royce Dart RDa.lOs. Planned for both military and commercial operations,it has rear loading ramp and is characterized by a very large, swept vertical tail surface. Gross weight is given as 36,380 lb andmaximum speed as 267 m.p.h. Bolkow-Entwicklungen Bo. 103 One of the two complete sur-prises at the Salon, the Bo. 103 is a free-flying version of the Bo. 102 fixed-base helicopter trainer. It is at present poweredby a three-cylinder, two-stroke ILO engine giving 40 to 50 h.p., but can have any engine between 50 and 85 h.p. The latter powerwould be provided by an Agusta vertical flat-four, or possibly a Porsche. With the smaller engines the Bo. 103 is only a free-flyingtrainer, but it could perform useful work with higher power. The structure is of steel tubes, with extensive use of glass-plastics forfairings. The main rotor has a single blade, made of glass-bonded plastics with foamed filling, with a bulky counterweight and atwin-paddle stabilizer bar. The tail-rotor, too, has a single blade. Main rotor r.p.m. are no less than 615. Gross weight is 965 lb,cruising and maximum speeds are 62 and 87 m.p.h. respectively and fuel is carried for four hours' flying. The Bo. 102 fixed-basehelicopter trainer, now being supplied to the German Air Force and army, are made either for operation on a metal base or on afloating cushion on water. The device offers stage-by-stage train- ing with realistic handling characteristics and no electronicequipment. Operating cost is accordingly very low. Breguet 940 News of some impressive performances by thisaircraft was given. With 1,200 total h.p. and weighing 14,700 lb, it has cleared 50ft from standstill in under 210yd, and was thenclimbing at l,380ft/min. It has demonstrated a full-stop landing from 50ft and a take-off back to 50ft again in a total distance of420yd. At 15,300 1b it has landed from 50ft in 250yd, including a ground-run of 110yd. Breguet 941 Integral The full-scale mock-up of the tacticalfreighter version of this extremely promising STOL was on view, and a passenger version—widi a rear-access stairway replacingthe freight ramp and doors—was also at Le Bourget. Forecast performance is remarkable. At 37,500 lb gross weight the 941will carry 40 passengers or 8,000 1b payload for 324 n.m. at over 250 m.p.h. Power is to be provided by four de Havilland Gnomes,giving a total of 5,000 h.p. With one engine failed it will reach 35ft in 787ft. Maximum gross weight is to be 44,000 lb andgreatest range 810 n.m. The makers claim that the 941 will be able to use l,300ft-long fields, allowing for a climb to 50ft andfailure of one engine. The first prototype should fly next year. Breguet 1001 Taon Both the existing prototypes, paintedbright blue, were statically displayed. It appears that neither the 1001 nor the Orpheus 12-powered 1005 Taon 5 has yet beenordered. Dassault Mirage IIIB The first example of this two-seat multi-purpose fighter was actually perched on the Dassault stand inside the Salon—where it looks remarkably small. It was fitted withits Nord 5103 missile and SEPR.844 rocket motor, and a pack of two DEFA Type 552 30mm guns was displayed beneath it. Dassault 415 Communaute The prototype at the Salon hadcompleted 18 hours' flying and looked extremely well. Powered by two Turbomeca Bastans giving 805 e.h.p. each, the Com-munaut£ may be either a crew trainer, command transport for ten passengers, ambulance, ground-attack or paradropping vehicle.Guns, bombs and rockets can be attached beneath the fuselage and wings, and the cabin is pressurized. The rudder is notbalanced but fully powered, a v-i. tailplane is fitted, and the ailerons are backed up by perforated spoilers. High-lift flaps andair brakes are also fitted on the slightly swept wing. The levered- suspension main legs shorten during retraction so that the gearunits, each of which has two 1-p. tyres, can be stowed within the narrow confines of the wing torsion box. Maximum range is1,600 miles, cruising speed approximately 300 m.p.h., maximum gross weight 13,230 lb, and take-off run less than 1,000ft. Dassault Etendard IVM The fourth pre-production Etendard IVM, painted dark grey and with its characteristic double- pointed radar nose was on display after first flying only last month. The span of the ailerons has been decreased, and perforated spoilers for lateral control are located ahead of the high-lift flaps. The outer portions of the wings fold, and the powerplant is an Atar 8. The low-level strike radius is 160 njn.; high-altitude radius is 440 n.m. and ferrying range 1,620 n.m. Dornier Do 27 In addition to military and civil Do 27s, Dornier were showing the new four/six-seat Do 27 Q4, powered by a Continental 240 h.p. engine instead of the 275 h.p. Lycoming. Dornier Do 28 Following numerous enquiries from abroad, Dornier have produced the Do 28 as the cheapest possible twin- engined version of the Do 27 STOL aircraft. Fuselage and wings are virtually identical in both machines, but the Do 28 has two 180 h.p. Lycoming O-360 engines mounted on a low-set stub wing carrying two fixed main undercarriage legs. Split flaps and fixed slots are also fitted to this stub wing. Cruising speed is 154 m.pJi. and range 800 miles, and the aircraft has shown very good slow-flying ability. Helkop-Air Girbel This is an entrant for the Governmentcompetition for an aeronef de grande vulgarisation. Two ver- sions are to be powered by Continental 90 h.p. or Lycoming150 h.p. engines and carry respectively 540 lb and 735 lb useful load, cruising at 87 and 106 m.p.h. A low-set wing has end-platesand ailerons and carries the mainwheels of the nosewheel under- carriage. An autogyro rotor provides for low-speed flight and isspeeded-up for take-off by a drive from the engine. It is claimed that a fixed-wing pilot can fly this aircraft without conversion. Hurel-Dubois HD.37 A model showed a two-deck fuselage,accommodating five cars and 28 passengers, which is to be com- bined with the high-aspect-ratio wing and struts of the HD.34and, initially, Hercules engines from Bristol Freighters. Later Rolls-Royce Dan 527s could be fitted. The aircraft was reportedto have been offered to Silver City; it is not yet known who will build it. Max Holste MH. 260 Super Broussard Displayed in modelform, this version of the Super Broussard is to be the initial production type, having a stretched fuselage and being poweredby two Bastan turboprops. Respectively for Sterling area and South American customers, the MH. 270 and MH. 280 will bepowered by Bristol Siddeley P.182s giving 1,064 sii.p. each, or by Lycoming T53s of 972 sJi.p. The prototype MH. 250, poweredby two P. & W. 600 h.p. Wasps, is expected later in the week. Morane-Saulnier MS. 880 Rallye Having only just made itsfirst flight, the- Rallye had been accumulating flying time before going to Le Bourget. It is an all-metal low-wing monoplane witha fixed nosewheel undercarriage and powered by a Continental 90 h.p. engine. Two or three occupants sit under a bulging,sliding canopy. This is one of the nine types in the semi-final stage of the official French competition for an aeronef de grandevulgarisation. Leading-edge slats and wide-chord, narrow-span slotted ailerons, combine with end-plates and extensive flaps toallow take-off, climb to 50ft and landing in a total of 1370ft. The trailing edges are blunt. Morane Saulnier MS. 1500 Epervier Displayed in a white, blue and brown colour-scheme, the first Epervier has now flown 123 hr, 29 of them with a Turbomeca Marcadau and the remainder with a Bastan. It completed its weapon trials at Cazaux in a week.
