Darts, J. Institution Royal Aircraft Establishment RAE Date 1984-08-31 Abstract Helix and Felix are standard loading sequences which relate to the main rotors of helicopters with articulated and semi-rigid rotors respectively. The purpose of the loading standards is, first, to provide a convenient tool for providing fatigue data under realistic loading, which can immediately be compared with data obtained by other organisations. Second, loading standards can be used to provide design data. This Report is the first of the two final project reports and describes the background to the definition of Helix and Felix, statistical content according to different counting rnethods and the results of fatigue tests used to assess them. Full inforrmation on generating Helix and Felix is not given in this Report, but is provided in Part 2.
