Nodal Diameter an overview | ScienceDirect Topics
Since the method of AIC requires that blademode shapes remain largely unchanged, it is proved for the 1 st flap mode that blademode shapes taken from finite element results of CSM 4 and CSM 14, both fitted to the CFDmesh to calculate the aerodynamic damping lead to similar results (figure 4). Since an EO 4 excitation will be enforced in the ...
