Design of an autonomous flap for load alleviation

In this paper the design of an experimental, aeroelastic set-up for a novel load alleviation concept using trailing edge flaps is presented. These flaps are autonomous in terms of power supply, control and actuation, which is especially advantageous as complex wiring to connect the control surfaces is redundant. The flaps are free-floating and therefore vibrate in response to turbulence. The vibrations are converted to electricity through an electromagnetic device. The harvested energy is used to power both actuators and accelerometers.
