Lead lag damper at blade attachment

When attempting to alter the elastomechanic and aerodynamic behavior of the rotor blade with its diverse couplings, and thus the susceptibility to vi- 

There are many parameters that can be adjusted to achieve desired features. A number of tuning/coupling effects can be achieved by the arrangement of the neutral axis, principal axes of inertia, or shear center relative to the position and direction of the loads. Moreover, the exploitation of the anisotropic properties of fibrous composites allows for additional tailorable couplings. Unlike the traditional rotor blade with almost constant structural properties over the blade length, future blades may be developed with the aid of advanced computational methods to evaluate arbitrary designs.
