A novel approach to optimizing control accuracy of pitch angle of the blades of an airplane propeller or wind turbine rotor by using laminated rubber (elastomeric) bearings in place of rolling element bearings so that the former's smooth torque vs. deflection characteristics minimally influence the balance of passive control torques upon the pitch axis due to calibrated springs and forces resulting from rotation speed and/or aerodynamic drag.
