Abstract

In order to establish a rational method for structural analysis of wind turbine rotor with respect to failure in ultimate loading, either in strength or fatigue fashion. Two famous methods in predicting the complicated nature of the two main lift and drag forces acting ‘normal and tangential’ forces on the rotor blade are discussed and numerical solution ‘iteration’ using the coefficients involved in establishing these forces is presented and, therefore are readily introduced in the analysis stage typically done by dynamics analysis codes.
