ABSTRACT:
The present rotor for rotary wing aircraft is of the type which is free of flapping hinges as well as free of lead-lag hinges. Such rotor shall have a simple structure and a small structural weight while simultaneously having a high operational reliability. To this end the rotor hub comprises upper and lower support or carrier plates made of a fiber compound material arranged in such a manner that the fibers extend substantially radially. The upper and lower support plates are spaced from each other by thrust arms or lands and the blade angle bearings are supported between the carrier plates of a fiber compound material.
