Double-layer wind turbine blade and modular wind power system
By designing a truss structure for double-layer wind turbine blades and a modular wind power system, the problem of blade bending and fatigue damage in horizontal axis wind turbines under strong wind conditions has been solved, improving the stability and safety of the wind turbine and enabling convenient transportation and installation.

Abstract
A double-layer wind turbine blade, comprising at least two blades (31) arranged up and down. The upper and lower blades (31) are connected by means of a support body to form a truss structure, so that the double-layer wind turbine blade has a bending resistance more than three times the bending resistance of a single blade. In addition, the present invention further relates to a modular wind power system comprising the double-layer wind turbine blade.
