Abstract

This paper concerns the active aeroelastic control of 2-D wing-flap systems operating in an incompressible flowfield and exposed to a blast pulse. The goal is to implement an active flap control capability to suppress the flutter instability and enhance the subcritical aeroelastic response to time-dependent external pulses. 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.
