HELICOPTER HUB MOUNTED VIBRATION CONTROL AND CIRCULAR FORCE GENERATION SYSTEMS FOR CANCELING VIBRATIONS

摘要

A rotary wing aircraft (520) including a vehicle vibration control system (409). The vehicle vibration control system includes a rotating hub mounted vibration control system (HMVS) (20) rotating with the rotating rotary wing hub (522). The vehicle vibration control system includes a rotary wing aircraft member sensor (552) for outputting rotary wing aircraft member data correlating to the relative rotation of the rotating rotary wing hub member rotating relative to the nonrotating body, at least a first nonrotating body vibration sensor (554), outputting at least first nonrotating body vibration sensor data correlating to vibrations, at least a first nonrotating body circular force generator (CFG) (530), fixedly coupled with the nonrotating body (524), a distributed force generation data communications network link (150), linking together at least the first CFG and the HMVS wherein HMVS and the CFG communicate force generation vibration control data through said link (150), the at least first CFG controlled to produce a rotating force with a controllable rotating force magnitude and a controllable rotating force phase, wherein the vibration sensed by the at least first nonrotating body vibration sensor is reduced.
