Abstract

A segmented wind rotor blade for a wind turbine generator system and the assembling method thereof are disclosed. The segmented wind rotor blade includes a blade root section (1) adjacent to a hub and at least one radial blade (2). Main girders (3) are embedded inside both the blade root section (1) and the radial blades (2). The blade root section (1) and each radial blade (2) are connected end to end through the main girders (3) connecting one by one. The effects of great connection intensity and less aerodynamic loss can be realized by the segmented wind rotor blade. Figure 3 is the representative figure.
