Abstract

See full text

The present disclosure is directed to a rotary wing rotor comprising one or more blades. Each blade has a torsion frequency around its span being substantially equal to a rotation frequency (Ω) of the rotor; torsion means twist to the rotation frequency of the rotor, in synchronization with said rotation; and comprising a material configured to dampen the torsion resonance, so as to avoid the resonance divergence.
