Origins
During the 1920s, the Italian aeronautical engineer Vittorio Isacco designed and constructed several unorthodox rotorcraft which became known as the Helicogyre. During 1929, Helicogyre K1171 was manufactured by British aircraft manufacturer S.E. Saunders Limited, and was delivered to the Royal Aircraft Establishment (RAE) at Farnborough by road, where it underwent limited testing before the programme was terminated. Although the Helicogyre did not use tipjets, being instead powered by piston engines positioned at the ends of the rotary wing, Isacco foresaw that these might be replaceable by jets.
