W.R. Kang¹, D.J. Lee¹; ¹KAIST, South Korea

This paper describe a periodically oscillating two trailing edge flaps based on SMA actuator, which is simple to install in the wing. A prototype wing model with two flaps was designed, and fabricated. Its operational performances were tested with and without flow conditions. Subsequently, unsteady aerodynamic forces corresponding to periodic flap motions were investigated experimentally.
