DISTRIBUTED ACTIVE VIBRATION CONTROL SYSTEMS AND ROTARY WING AIRCRAFT WITH SUPPRESSED VIBRATIONS

摘要

An aircraft (20) with at least one rotating machine (22) including: a power source (26), outputting a plurality of electromagnetic force generator power outputs, an aerostructure (24) including a plurality of distributed actiye vibration control system sites, at least a first distributed active vibration electromagnetic force generator (30), including a first distributed electronic control system (32) and a first electromagnetically driven mass (34), the first force generator fixed to the aerostructure at a first site (28), at least a second distributed active vibration electromagnetic force generator including a second distributed electronic control system and a second electromagnetically driven mass, the second force generator fixed to the aerostructure at a second site, a plurality of electrical power distribution lines (40), connecting the electromagnetic force generators with the power source-with the power outputs outputted to the electromagnetic force generators, a distributed force generator data communications network (50) linking together the at least first. and second distributed electronic control systems wherein the control systems communicate force generator vibration control data through the distributed force generator data communications network independently of the electrical power distribution lines to minimize the troublesome vibrations.
