Wind turbine blade design and three-dimensional solid modeling study

Dandan Zhang

Abstract

In the light of the best designed attack angle of large wind turbine blade and the non-lin-ear changed lift coefficient,it adopts Wilson design to design the aerodynamic shape of 1.2MW wind tur-bine blade based of Pituitrin-Momentum Theory.Also,the three-dimensional modeling method of wind turbine blade is put forward in the paper.The method uses the point coordinate transformation theory to calculate the actual coordinates in space of the blade airfoil cross-sections,then uses the three-dimension-al surface features of Pro/ENGINEER to model the blade three-dimensional solid modeling.
