WITHDRAWN: Characteristics of a Swept and TaperedWing in Dynamic Motion

An aspect ratio 4 swept and tapered wing was investigated experimentally undergoing static and dynamic motions exploring the effect of pitch, roll, and yaw. The wing has a taper ratio of 0.27 where the trailing edge swept forward 30◦ and leading edge is unswept. The results obtained for this wing were compared to those of a cantilevered semi-span wing with the same geometry. The effect of static yaw and roll on the aerodynamic performance of the wing were also explored. It was found that roll has small effect on the lift, drag, and pitching moment, whereas yaw largely impact the aerodynamic forces due to large asymmetric flow structures that form on each side of the wing. Sinusoidally pitching motions showed that the mean angle plays a significant role in the size of the hysteresis loops and the maximum lift and maximum drag. Ramp-up/ramp-down pitching motion was also explored and showed transitory behavior during the onset of ramp up and ramp down. These transient are likely affected by the change in acceleration at the onset and conclusion of the motion.
