Description

The aerodynamic performance of a novel Fishbone Skin-Actuated-Camber (SAC) morphing wing design, which actuates its skin to change its effective camber, was studied both experimentally and numerically. Force-based experiments were conducted at the University of Dayton Low Speed Wind Tunnel (UD-LSWT) to compare the performance of four morphing wing designs with different hinge locations, two ideal trailing edge flap wings, and one conventional trailing edge flap wing. All test articles have an Eppler 479 airfoil, an effective aspect ratio of four, and were tested within an angle of attack range of -15° and 15 °. The novel design achieved effective camber change without any buckling, maintaining comparable aerodynamic performance to ideal flap wings at a Reynolds number of 270,000. At a Reynolds number of 400,000, the morphing shows a lower drag than the ideal flap wing. Simulations from FlightStream®, a numerical solver correlated well with experimental lift data, with the morphing wing's pressure contours indicating reduced flow separation and gradual pressure change on the upper surface when deflected.
