ABSTRACT:
The rotor blades or wings of the present helicopter rotor structure are interconnected by tension or carrier bars so that diametrically opposite rotor blades or wings form a pair. The tension bars are substantially stiff against bending, but permit some bending. The blade angle bearings are movable in the blade flapping direction, as well as in the blade lead-lag direction. At least one blade angle bearing of a pair of such bearings permits an axial movement of the respective tension or carrier bar, whereby the latter is able to take up bending loads.
