Abstract
A segmented blade module structure and a molding method thereof are disclosed. The blade module includes a blade shell, a beam and a web provided in the blade shell, and the beam comprises a connecting beam, a trailing edge beam and an auxiliary beam plate, and a connecting structure is provided at an end of the connecting beam. The beam and the web integrally formed of composite materials constitute a bearing frame that forms a contour shape conforming to the blade, and the blade shell is formed by a skin wrapped on the bearing frame. The auxiliary beam plate is arranged corresponding to the area from the middle portion to the trailing edge portion of the blade shell to ensure that there is sufficient contact area between the beam and the blade shell to avoid instability of the blade shell, ensuring the structural stability of the segmented blade module.
