Abstract

This paper concerns the active aeroelastic control of 2-D wing-flap systems exposed to an incompressible flowfield. The goal is to implement an active flap control capability as to suppress the flutter instability and enhance the subcritical aeroelastic response to gust or blast loads. To this end, a combined control law is implemented and its performances toward suppressing flutter and reducing the vibrational level in the subcritical flight speed range is demonstrated.
