GS0516 地面効果内における翼のヨーイング特性

抄録

When a wing moves near a ground, a ground effect occurs, and drag force becomes small, and lift becomes large. In the case of a inversion wing, downforce occurs. There are many studies of the ground effect in pitching motion, however, there are few studies in yawing motion. The purpose of this study is to clarify relationship between ground effect and yawing motion. Yaw angle reduces the influence of ground effect. In the case of downforce, separation occurred by yaw angle and distance from ground. When yaw angle become larger, separation region decrease.
