This project aims at investigating active and partially passive wing control functions combining active flutter control with “rigid-body“ (manual flight modes and/or autopilot) and flexible laws (manoeuvre and gust load alleviation functions). The load alleviation functions shall significantly reducing gust and manoeuvre loads down to a level equivalent to steady 1.5g to 2.0g flight and the flutter control law shall permit to fly right at the limit or even slightly beyond the open-loop flutter speed. Sensor networks integrated into the wings and fuselage will facilitate accurate evaluation of the aircraft current and future state. If this information is integrated into the flight controls, uncertainties can be reduced and flight controller performance can be significantly improved. By doing so, significant mass saving can be obtained, assuming no change in planform of the wing. Part of these savings can also be traded against an increase in aspect ratio of the wing, i.e. against an improvement in aerodynamic efficiency of the aircraft. This project builds upon the results of ARGO.
