VIBRATION MODES OF A ROTATING THREE–COMPOSITE–BLADES ROTOR

The purpose of this paper is to provide the recent results of dynamics of a rotating structure (a rotor) composed of three flexible composite beams attached to a rigid hub. The crucial elements of the rotor are elastic beams which are originally described by a set of Partial Differential Equations (PDEs). Dynamics of the model strongly depends on the beam laminate stacking sequence and beams preset angle.
