in the early 1960s, under an italian government contract, fiat aviazione designed the model 7002, a medium-capacity transport helicopter. it had an unusually-shaped fuselage made from light-alloy sheets to provide accommodation for two crew and up to five passengers. the fuselage was mounted on a skid landing gear and the fuselage had a simple tailboom with a tail rotor. a two-blade main rotor was mounted above the fuselage, with the rotor driven by compressed air propulsion nozzles at the blade-tips. the compressed air was generated by a fiat 4700 turbo gas generator located in the rear fuselage. the prototype helicopter first flew on 26 january 1961 but no production aircraft were built.
