i ' ,ta 204b I NTERNATIONAL SURVEY... 9 Rotor diam, 34ft 9iin; fuselage length,29!r <Min; weight empty, 1,7011b; gross weight, 2.h671b; max speed, 99 m.p.h.; cruising speed,86 m.p.h.; rate of climb at s.l., 820ft/min; hovering ceiling in ground effect, 9,515ft;absolute ceiling, 19,355ft; endurance, 3hr. Societa Per Azioni Fiat Cor so Giovanni Agnelli 200, Turin Model 7002 Now undergoing trials, thisaircraft will be seen from the photograph to be of unconventional layout. The two-blade main rotor is driven by cold jets, compressed air being supplied by a Fiat4700 turbo-generator in which the turbine- driven air-compressor is operated by a hot-gas generator, or primary engine, that embodies almost completely the componentsof the Fiat 4002 turbojet. Although, in the absence of torque reaction, it would havebeen possible to abolish the tail rotor, it was in fact decided to install a small ductedrotor, mechanically driven by the main rotor, for directional control. This ensuresmaximum manoeuvrability at low forward speeds and in autorotation. The fuselage ismade up of light-alloy sheets and embodies very large transparent panels. A typicallayout will provide for one pilot and six passengers. • Rotor diam, 39ft 4in; fuselage length,20ft; empty weight, 1,3201b; gross weight, 3,0851b; cruising speed, 84 m.p.h.; serviceceiling, 11,150ft. Costruzioni Aeronautiche Giovanni Agusta Cascina Costa, Callarale Bell 47 Series In addition to the Bell47G-2 and G-3, Agusta are offering the Agusta Bell 47J-3, under the designationSuper Ranger. This seats four passengers on a single bench-type seat, in addition tothe pilot. The engine is a Lycoming VO-540. A-104 Helicar A side-by-side two-seater,the Helicar can be assembled or taken apart by one person. The engine is an AgustaA-140V of 140 h.p. and the rotor is two- bladed. • Rotor diam, 26ft lin; fuselage length,20ft lOin; weight empty, 8381b; gross weight, 1,4111b; max speed, 103 m.p.h.; cruisingspeed, 84 m.p.h.; max rate of climb at s.l., 810ft/min; hovering ceiling in ground effect,9,840ft; max range, 205 miles. Model 102 This Agusta-designed heli-copter uses a Bell type rotor and has a Pratt & Whitney R-l340 engine of 600 h.p. Forstage-lengths of up to 62 miles—which, the makers say, represent the most frequentcase for regularly scheduled passenger lines, tourist services, etc.—it will carry ninepassengers plus 2501b of baggage or equip- ment. The supercharged engine permitscargo transport to be undertaken at alti- tudes up to 11,500ft. • Rotor diam, 47ft 7in; fuselage length,41'*, 9in; empty weight, 4,0001b; gross weight, Ofi'-Olb; max speed, 121 m.p.h.; cruising speedfor best range, 100 rn.p.h.; service ceiling, 14,oOOft; hovering ceiling in ground effect,9.500ft; max endurance 3hr 20min. Agusta Bell 102 Model 204B This aircraft differs from itsAmerican counterpart (Bell Iroquois) in having a de Havilland Gnome. Agustaremark: "The Gnome has been specially designed to give ease of maintenance, andoperators will also have the facility of extensive in-service component replacementschemes. These, together with the con- siderable development background of theengine, ensures a very high overhaul life for the Gnome. This is also assisted by thereduced operating conditions of the Gnome in the 204B resulting from the need torestrict the engine output to the power requirements of the rotor system. Furtheradvantage is taken by utilizing this reserve of power for enhanced operation of the 204Bat altitude and in hot weather condition."' • Gross weight, 8,5081b; max speed, 133m.p.h.; range, 234 miles. AZ-101G A prototype of this 30-pas-senger helicopter has been ordered by the Italian Air Force. This will be powered bythree de Havilland Gnomes, rated at 1,050 h.p. for take-off. The main and tailrotors are four-bladed and the under- carriage is four-wheeled, the rear wheelsbeing provided with brakes and the front wheels with shimmy dampers. There is arear loading ramp which may be kept open in flight to permit the dropping of para-chutists. Several versions, including one for anti-submarine operations, are inprospect. • Rotor diam, 64ft; fuselage length, 54ft lin;empty weight, 12,5661b; gross weight, 24,0301b; max speed at max cont power, 143 m.p.h.;cruising speed for max range, 125 m.p.h.; rate of climb (max cont power), l,280ft/min;hovering ceiling in ground effect, 9,840ft. Nederlandse Helicopter Industrie N.V. Veerdam 44, PapendrechtNHI H-3 Kolibrie Designed for extreme simplicity, the Kolibrie is propelled byramjets—one, of 441b thrust, on each of the two blade tips. This helicopter has beendeveloped with a particular eye to its use for agricultural purposes, and in this connec-tion the makers have developed what they call a "helicar." They state: "It is unecono-mical to fly the helicopter on non-productive flights since road transport is many timescheaper. It is possible to apply this method of transport to the Koiibrie by using aspecial trailer. The NHI has developed a 'helicar,' that fully meets the requirements.This helicar can be used as a landing plat- form, because of its large and flat loading-floor, which is equipped with foldable side flaps. The low total height of trailer plushelicopter makes it possible to pass normal viaducts, power lines, etc. The most import-ant equipment is the special construction to support the rotor blades with mountedengines during transport." The following performance data apply toa gross weight of 1,5401b, for which the aircraft is not at present certificated. 9 Rotor diam, 32ft 8in; empty weight,5501b; max speed, 68 m.p.h.; cruising speed (max endurance), 35 m.p.h.; rate of climb (at35 m.p.h. air speed), 680ft/min.
