Patent ID: 8162606

Claim:
A rotary wing aircraft, said rotary wing aircraft having a nonrotating aerostructure body and a rotating rotary wing hub, said rotary wing aircraft including a vehicle vibration control system, a rotating hub mounted vibration control system, said rotating hub mounted vibration control system mounted to said rotating rotary wing hub with said rotating hub mounted vibration control system rotating with said rotating rotary wing hub, a rotary wing aircraft member sensor for outputting rotary wing aircraft member data correlating to said relative rotation of said rotating rotary wing hub member rotating relative to said nonrotating body, at least a first nonrotating body vibration sensor, said at least first nonrotating body vibration sensor outputting at least first nonrotating body vibration sensor data correlating to vibrations, at least a first nonrotating body circular force generator, said at least a first nonrotating body circular force generator fixedly coupled with said nonrotating body, a distributed force generation data communications network link, said distributed force generation data communications system network link linking together at least said first nonrotating body circular force generator and said rotating hub mounted vibration control system wherein said rotating hub mounted vibration control system and said first nonrotating body circular force generator communicate force generation vibration control data through said distributed force generation data communications network, said at least first nonrotating body circular force generator controlled to produce a rotating force with a controllable rotating force magnitude and a controllable rotating force phase, said controllable rotating force magnitude controlled from a minimal force magnitude up to a maximum force magnitude, and with said controllable rotating force phase controlled in reference to said rotary wing aircraft member sensor data correlating to said relative rotation of said rotating rotary wing hubrotating relative to said nonrotating body wherein said vibration sensed by said at least first nonrotating body vibration sensor is reduced.
