Real Time Active Helicopter Vibration Control And Rotor Track And Balance Systems

Abstract: Rotary wing aircraft electronic control system including a tachometer (552) and a plurality of nonrotating body vibration control sensors (554) outputting at least first nonrotating body vibration sensor data correlating to vibrations. The system includes a plurality of nonrotating body force generators (530) to input a vibration control force into said nonrotating aerostructure body. The system includes a data communications network link (150) linking together the nonrotating body force generators the tachometer sensor  the vibration control sensors  and an actuating force generator rotor track balance electronic controller (411)  the actuating force generator rotor track balance electronic controller including at least a first computer processor with the actuating force generator rotor track controller controlling the nonrotating body force generators to input vibration control forces into the nonrotating aerostructure body and computing a rotor track solution for aircraft rotor blades.
