PRELIMINARY ASSESSMENT OF A WARPING WING CONFIGURATION IN ROLLING CONTROL

The preliminary analysis and the possible advantages of a morphing solution replacing the traditional hinged aileron configuration has been analyzed in order to evaluate its energy efficiency in UAV configurations with limited payload capacity and power available for flight. The parameters considered are the wing aspect ratio, the torsional stiffness, the position and the aileron deflection and the consequent actuation rib rotation in the morphing solution. The analysis showed that the morphing solution is very advantageous in all cases requiring high rolling moments with a more evident advantage at high aspect ratios. The traditional solution still remain advantageous at low aspect ratios and low rolling moments.
