Blade Reverse Design of Large Wind Turbine

Abstract

Blade is one of key parts in wind turbine. Its shape design and airfoil selection directly affects the performance of wind turbine. This paper presented reverse redesign method of blade of large wind turbine and developed a blade airfoil automatically generating system. The redesign of blade is achieved through such processes as reverse measurement, reverse CAD modeling and blade reverse model analysis as well as determining the formula of blade section parameters. The blade airfoil automatically generating system has been applied.
