Active Vibration Control of the RSRA/X-Wing Vehicle Using a Time Domain Approach

The strong vibration environment of the RSRA/X-wing vehicle necessitates effective vibration suppression in both steady state and dynamic flight conditions. The circulation control system to be utilized on this vehicle provides a unique mechanism for vibration suppression. This presentation describes an active controller based on time domain feedback that utilizes muiticyclic blowing, although the concept is also readily applied to conventional swashplate control. The concept and design procedure are presented and the results of closed-loop computer runs using an aeroelastic simulation of the X-wing rotor are shown
