Abstract

A new structure named 'collapsible fan blades' is presented in this paper, which is fixing blades and a spring via metal rods. In this structure, based on Betz theory, the furl of the fan blade is realized by compressing the spring. On the purpose of getting relation between wind speed and power, this paper firstly derived the expression between wind speed, wind force and wind turbine power. Then presented the structure and working principle of the collapsible fan blades. By means of force analysis and moment analysis, an expression on a randomly given wind speed and the spring shrinkage was proposed. In this expression, different wind speeds corresponded to different spring compression, so that the fan blades' angle can be figured out. With this angle, after calculating windward area, the power of wind turbines under different wind speeds can be obtained.
