© Universal Technology Corporation, 2018. This paper presents the installation and wind tunnel testing of a camber-morphing trailing edge system on an aeroelastic wing. Such morphing system, called High Bandwidth Morphing Actuator (HBMA), is capable of achieving actuation frequencies up to 25 Hz with varying amplitudes. The installation of the morphing actuator in the aeroelastic rig is firstly achieved. Then the aeroelastic behaviour of the entire system is assessed and an active controller is designed, by using the Receptance Method, with the aim of increasing the damping of the first bending and torsional modes. The HBMA proved to be capable of introducing the desired control input that resulted in an increase the flutter velocity up to 10%.
