Abstract

Abstract

It is necessery to calculate the transient responses of blades precisely in analysis of blade damage due to bird impact.Because the deformations of blade can influence the distribution and magnitudes of bird impact loads,the coupling of the bird impact with blade deformation has a remarkable influence on the transient responses of the blade.A simple and effective method is provided to analyze the responses of blades with consideration of this coupling.Taking a model blade as an example,its influence extent is also sized up.
