716 FLIGHT, 27 May 1960 HELICOPTERS OF THE WORLD . . . prospect. The Kolibri has a steel-tube air-frame, housing a three-seat cabin forward and powerplant amidships, with metalskin. The tail boom is fabric-covered. Power for the three-bladed main rotorand twin tail rotors is provided by a Lycoming VO-435-A engine, giving 260h.p., driving the main rotor through a two- stage 10:1 reduction. The conical housingfor the main vertical shaft also forms the transmission oil tank and further drivesare taken for the tail rotors, engine-cooling fan and a series of oil pumps for lubrica-tion and hydraulic power. Engine oil is used in the hydraulic system.• Rotor diam, 30ft lOin; fuselage length, 27ft 3in; gross weight, 2,6451b; cruising speed,87 m.p.h.; absolute ceiling, 14,760ft. Costruzioni Aeronautiche Giovanni Agusta Cascina Costa, Gcdlarate Bell 47 Series Agusta are constructingunder licence helicopters of the Bell 47G and J series. These are essentially thesame as the American machines, but one notable development is a version of the47J seating pilot and four passengers (the latter on a single bench seat). In addition,the following types, partly or wholly of indigenous design, are being developed. AZ-101G A prototype of this 30-pas-senger helicopter has been ordered by the Italian Air Force. This will be poweredby three 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 ofparachutists. Several versions, including one for anti-submarine operations, are inprospect. • Rotor diam, 64ft; fuselage length, 54ft lin;empty weight, 12,5661b; gross weight, 24,030 lb; max speed at max com. 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. Model 102 Powered with a Pratt &Whitney R-1340 piston engine of 600 h.p., the Model 102 will carry up to nine pas-sengers plus 2501b of baggage or equip- Bolkow Bo 102 Borgward Kolibri I Agusta AZ-101G ment (up to a range of 62 miles). Forranges up to 220 miles it will carry seven passengers plus 2601b. The rotor systemis of the classic Bell type and the aircraft is of uncommonly clean design. • Rotor diam, 47ft 7in; fuselage length, 41ft 9in; gross weight, 6,2801b; cruising speed for best range, 100 m.p.h.; hovering ceiling (free air), 6,050ft. A104 Helicar Of this new helicopterthe makers state: "In order to complete the series of helicopters built at its plantthe company has decided to start manu- facturing a low-priced helicopter havingreduced dimensions and requiring low maintenance. This helicopter is the ModelA104. It is derived from the Agusta Model A103. The A104 may be supplied eitheras a single-place or two-place. It is powered by an engine rated at 140 h.p.,which permits it to obtain outstanding performance, thus allowing accomplish-ment of a large variety of operations, even at high altitudes."
