Rotor having rotor blades which are assembled to form blade pairs

摘要

In the case of a two-bladed rotor, the two rotor blades (1) are assembled via a torsionally soft connecting link (2) which is fixed to the rotor hub (5), the blade incidence angle of the respective rotor blade taking place ÄsicÜ via a torsionally stiff control sleeve (4) which extends along, without making contact, from the rotor hub to this blade connecting link (2) and is rigidly connected to the blade (1.1) itself. In order to support the controlled end of these two control sleeves (4), the blade connecting link (2) is split in the centre at right angles to the plane of the rotor, and a bearing (9) (which moves in rotation and angle) of the control sleeves (4) is produced in the centre (5) of the rotor hub via in each case one supporting link (7) which passes through this gap (6) without making contact. <IMAGE>
