Abstract

Abstract 1. A rotor more especially of a rotary-wing aircraft, having radially outwardly directed rotor hub arms (2) each for holding a respective rotor blade (3), which has a blade neck portion (3.2), which is torsionally pliant at least for blade pitch movements, between the blade wing and the blade root, in which the blade pitch control is effected by means of control members arranged in the rotor hub by way of a control shaft (7), introduced so as to be movable through a rotary angle into the respective rotor hub arm and coaxial with the blade angle axis, and a blade control lever (10) connected thereto in a torsionally-fast manner and to a torsionally rigid sheat (6) which surrounds the blade neck portion in a contact-free manner and which is securely connected radially outwardly therefrom to the rotor blade, and in which the torsionally rigid sheat (6) is a fibre composite material body having a structure which is flexible in relation to beat and swivel movements as well as elongation under centrifugal force of the rotor blade (3).
