Active Control Rotor Using No Swashplate

This proposed effort is to develop an approach to eliminate the requirement for hydraulics, swashplates and control rods on conventional helicopters. A servo tab on a servo tab approach is used to provide a two step amplification of power using the energyin the airstream to provide the cyclic, collective and high-frequency control for flight control and vibration reduction of a full size rotor using small electric actuators in the rotating system. The servo tab is on the leading edge of the rotor forreduced trim drag. This technology is applicable to any new or existing commercial or military rotary wing aircraft. Benefits include increased vehicle fatigue life and reliability, reduced acquisition and maintenance costs, reduced vibrations, drag andstructural weight
