Abstract : An aerodynamic rotor having a flexible blade comprising a plurality of planar layers and an anvil having configured bearing areas engagable with the flexed blade is presented. The plurality of layers are slidably movable in a shearing motion with respect to other layers. The blade is secured by the anvil with the configured bearing areas being engagable with an adjacent portion of the blade when the blade is flexed by forces created by the driven rotory motion of the anvil about an axis of rotation. Such a rotor with a laminated blade exhibits reduced head moment forces and reduced stress/strain forces within the blade thereby permitting improved reliability and maintenance.
