An inner rectangular or tapered section () next to a blade root for said blade's connection to a rotor hub rotating about a rotor axis of said helicopter. A middle section () is adjacent to the inner section () and opposed to the blade root. The middle section () is forward swept over a distance along the span of the blade (). An outer section () lies between the middle section () and the blade tip (). The outer section () is back swept along a further part of the span of the blade (). The outer section () includes a parabolic shape towards the free end of the blade tip ().
