Abstract
To reduce the strength of tip vortex of the fixed wing, a horizontal wing-let splitted into two parts was utilized, and the interaction between vortices generated by these wing-lets was investigated by the hot-wire anemometry. The process of vortex forming and merging was clarified by measurements of velocity vectors and their contours at five downstream cross-sections; 0.05C(chord length), 0.2C, 0.5C, 1.0C and 2.0C. Both vortex-lets formed by each wing-lets rotate counterclockwise and merge into a larger single vortex within a short downstream distance, 0.5C in this case. The strength of the merged tip vortex turned out to become smaller than that of the plain wing tip near the vortex core.
