The Fiat 4700 was an Italian turbo-generator developed by Fiat Aviazione under contract to the Italian Defence Ministry and used to power the experimental Fiat 7002tip jet helicopter.[1]
The Fiat 4700 was developed to provide power in cold-jet driven helicopters.[1] The 4700 was a turbo-driven air compressor driven by the primary engine, a turbojet engine based on the Fiat 4002.[1] The compressor and primary engine are mechanically independent.[1] The engine is mounted vertically to reduce the length of the compressed-air ducts to the rotor.[1] The engine was used on the Fiat 7002 helicopter which first flew on 26 January 1961 where the Fiat 4700 was used to power the cold tip-jets on the two-blade rotor.[2]
