Zusammenfassung:The present disclosure relates to a blade and a rotor of a rotor craft, and a rotor craft. The blade includes a blade root, a blade tip, and an upper aerofoil and a lower aerofoil disposed vertically opposite to each other. One sides of the upper aerofoil and the lower aerofoil are connected to form a front edge, and other sides of the upper aerofoil and the lower aerofoil are connected to form a tail edge. The upper aerofoil is defined by an upper aerofoil characteristic line formed by (kx, ky, kz) defined by a plurality of coordinate pairs. The lower aerofoil is defined by a lower aerofoil characteristic line formed by (kx, ky, kz) defined by a plurality of coordinate pairs.
