Active flutter suppression using trailing-edge and tab control surfaces

Research output: Contribution to journalArticlepeer-review


An optimization procedure, based on the aerodynamic energy concept, is applied to the problem of flutter suppression using trailing-edge (T.E.) and tab control surfaces. A control law is assumed which allows the T.E.-tab system to be driven by both linear and rotational sensors, and the optimum control law parameters are determined. Results are presented which indicate the capability of the T.E.-tab control system to suppress flutter. A comparison is also made between the T.E.-tab and the leading-edge (L.E.)-T.E. control systems which shows their relative effectiveness, together with some aspects connected to the realization of the control law.
