The Fiat 7002 is a medium-capacity dual-control helicopter for passenger transport and general-purpose duties, of which a prototype is under construction. The main rotor is of the "cold jet" type, and is turned by ejecting compressed air, without any form of combustion, from nozzles at the blade-tips. Compressed air is provided by a Fiat 4700 turbogenerator. A small ducted tail rotor, mechanically-driven by the main rotor, ensures good manoeuvrability at low forward speeds and in autorotation. TYPE: Single-rotor general-purpose helicopter. ROTOR SYSTEM: Two-blade main rotor on tilting hub. Blades have leading-edge and spar of welded stainless steel sheet. Ducts in leading-edge and spar carry compressed air to propulsion nozzles at blade-tips. Blades linked together by steel strips which bear centrifugal loads and permit pitch variation. Blade chord 0.43m. Small ducted two-blade tail rotor. FUSELAGE: Light alloy sheet structure in three portions. Front portion accommodates side-by-side pilot's seats; centre portion accommodates passengers or payload; rear portion carries power plant. Short semi-monocoque tail-boom carries ducted tail rotor and small horizontal stabiliser. LANDING GEAR: Twin tubular-skid type. POWER PLANT: One Fiat 4700 turbogenerator with equivalent power of 530hp housed vertically in rear of fuselage. Fuel in tanks above cabin, with total capacity of 525 litres. ACCOMMODATION: Two pilots, or pilot and passenger, side-by-side in front portion of fuselage, with dual controls. Large sideways-opening door on each side. Centre cabin for five passengers or 2.5m3 of freight, etc. In casualty evacuation role can carry pilot, attendant, two litters internally and two externally. Very large door on each side of main cabin. Jane's All the World's Aircraft, 1959-60
General purpose experimental helicopter using the cold-jet propulsion system. The compressed air ejected by the blade-tip nozzles was provided by a 530hp Fiat 4700 turbogenerator. G.Apostolo "The Illustrated Encyclopedia of Helicopters", 1984
In 1959, the Societa per Azioni Fiat was awarded an Italian Defence Ministry contract to design and build a medium capacity helicopter for use by the Italian Air Force. Fiat's Model 7002 had an unusual flat-sided semi-round fuselage section with a small girder tail-boom on which was mounted a shrouded tail rotor. The rear quarter of the main fuselage housed a Fiat 4700 turbine which drove a compressor feeding cold tip nozzles on the two-blade rotor. The Model 7002 could carry two crew and up to five passengers. The sole prototype flew on 26 January 1961, but development was discontinued in 1963. Fiat then designed a new high-speed three-seat helicopter, designated Fiat 7005, which had a pusher propeller mounted immediately behind the rotor pylon. This was not built and Fiat discontinued helicopter development in 1967. R.Simpson "Airlife's Helicopter and Rotorcraft", 1998
