A theoretical approach is presented with the object of determining the natural frequencies and hub characteristics of a single-rotor helicopter in free ground vibration for use in the analysis of self-excited mechanical oscillations of hinged rotor blades. The method is intended to obviate the experimental determination of these parameters, a technique which necessitates the construction of the helicopter before its vibrational features can be explored.
