Abstract

The helicopter has several rotor blades and rotor hubs rotating about a vertical axis. The hub has for each blade a radial blade holder which is flexible in a blade deviating directon. A blade holder has blade angle setting pivot on its outside end. The arrangement has bearing with elastomer components which reduce the overall bearing size to a minimum. The blade angle adjusting pivot (15) has a tubular component (24) which is connected with the rotor blade (17). This tubular component (24) is supported on inner and outer elastomer bearings (22, 23) arranged on a spindle (19) held on the blade holder (14). An elastic shearing connection (26) of the outside bearing is arranged so that the tubular part and associated rotor blade (17) can carry out blade swivelling movement about a geometrical centre (18) of the inner bearing (22).
