Active Flutter Suppression Using Cooperative, High Frequency, Dynamic-Resonant Aero-Effectors

Abstract

An investigation of the use of actuators that cause aerodynamic disturbances that could be used for flutter control was investigated. Flutter control requires large disturbances to produce the aerodynamic loads needed to oppose the flutter forces. As a result, oscillating fence actuators that have low power consumption and high control authority that scales with flight speed were studied. These fence actuators were tested in laminar and turbulent boundary layers to characterize the disturbances they produced. They have also recently been studied on a two-dimensional airfoil. By modeling the disturbances produced by these actuators, control modeling indicated that they could be used to dampen flutter-like motion. As a result of these initial findings, it is concluded that the use of such actuators for flutter controls is promising and should be investigated further.
