Abstract
The blades or wings of a rotary wing aircraft are secured to the rotor head n a non-rigid manner by means of a carrier bar, however, without any flapping hinges and without any lagging hinges. The carrier bar is supported on the rotor head. The connection of each wing to the respective end of the carrier bar is such, that the longitudinal wing axis is excentrically displaced relative to the central longitudinal axis of the carrier bar in the direction in which the forces of the air are effective. The displacement or spacing between the two axes is such that at least a partial compensation of the occurring bending moments is achieved.
