| description | The embodiment of the invention discloses a blade structure and a design method, the blade structure is used for passive load reduction, and the blade structure comprises a blade body comprising a shell; the shell comprises a reinforcing area and a torsion weak area, and a first main beam and a web plate are arranged on the inner wall of the reinforcing area; the first main beam and the web are used for reinforcing the rigidity of the reinforcing area; the torsional rigidity of the weak torsional area is smaller than that of the reinforced area. According to the blade structure provided by the invention, the torsion weak area is arranged on the blade body, and the bending-torsion coupling effect is improved by reducing the torsion rigidity of the torsion weak area. Compared with an aeroelastic cutting method, the constraint of the chord length of the blade is eliminated, and the adjustment space is larger; compared with a sweepback load reduction mode, due to the fact that the torsional rigidity of the weak t |
