The underlying theory is presented for determining blade and rotor/tower vibration and dynamic stability characteristics. The dynamic analysis of horizontal axis turbines may be divided into two convenient areas, namely, (a) the investigation of the aeroelastic and response of a single blade on a rigid tower, and (b) the investigation of the mechanical stability and vibrations of the rotor system on a flexible tower. With a reasonable understanding of the behavior in these two areas, the completely coupled blade-tower aeroelastic system can be better understood, and dynamic problems can be better assessed.
