306 Helicopters 1954 stretcher cases), or for ground attacks with infantry weapons. In civil operation it could serve for agricultural spraying, police work, power line inspection, forest patrol, and newsreel photo graphy. As a trainer the type has obvious advantages. Performance figures quoted hereafter take into account the increase in power of the Palouste, now under development. Data: rotor diam., 32.8ft; normal gross weight, 1,390 lb; max. weight with vertical take-off at s.L, 1,580 lb; max. speed, 81 m.p.h.; cruising speed for range, 62 m.p.h.; cruising speed for endurance, 37 m.p.h.; fuel consumption at cruising speed (gasolene or kero- sine) for max. range, 220 Ib/hr, for max. endurance, 185 lb/hr; service ceiling, 10,000ft. LUALDI/TASSOTTI • A small helicopter powered by an 80 h.p. Continental engine and designed to cruise at about 75 m.p.h. has been designed by the Italians Carlo Lualdi and Sergio Tassotti, and is being built in the Lualdi works near Udine. The main rotor diameter is about 24ft, the fuselage some 20ft long, and endurance should be approximately 2\ hr. AMERICAN HELICOPTER XH-26 JET JEEP • This experimental single-seater is powered with pulse-jets and weighs only 300 lb empty, although the designed gross weight is 900 lb. The pulse-jets are of the same manufacture and are located on the tips of the two-blade main rotor. Each has only one moving part, which, when worn, can be replaced in a matter of a few minutes. Fuel can be gasoline, kerosine or diesel oil. Though stand ing 6ft high, the machine can be collapsed into a 5ft x 5ft X 14ft container and can be dropped by parachute. Having been un packed, it can be in the air within 20 minutes on its missions of observation or reconnaissance. The three-wheel undercarriage shown in the photograph is interchangeable with a twin skid gear. Top speed is about 80 m.p.h. and endurance 1J hr. BELL.. MODEL 47G • This world-famous helicopter is used commercially, and in the service of many air forces, in numerous variations; thus, in the U.S.A.F. it appears as the H-13B, D< Eaod G, and in the U.S. Navy as the HTL-1, 2, 3, 4, 5 and 6. In Italy the Model 47D-1 is built under licence by Giovanni Agusta and is known as the Agusta-Bell. Subject of our descrip tion'is the latest civil model, the 47G. The two-blade main rotor has laminated wooden blades and a osteel stabilizer bar. A new feature is a synchronizing elevator, which is linked directly into the control system and provides greater, stability with a gready increased e.g. travel. The engine is a six-cylinder Franklin 6V4-200C32 of 200 h.p., which supplies power to the main rotor, tail rotor, generator and cooling fan through a two-stage planetary transmission. Although the three- abreast. cockpit has a bubble-type Plexiglass canopy, the remainder of the fuselage is left as open lattice work. The twin landing skids are of aluminiuifi alloy, and ground-handling wheels and mooring and towing attachments are standard. An alternative fitment is a quick-change flotation gear in the form of twin pon toons, which convert the Model 47G into a very effective machine for all' types of amphibious operation—especially from marsh and swampland. Of the improvements incorporated in the 47G we have already mentioned the synchronized elevator; additionally, there are twin graviry-feed fuel tanks, which give 38 per cent more range, and an improved electrical system.
