Keywords: spiroid winglets, subsonic transport

Spiroid winglet has been proved to be useful in some of the subsonic transport. This study first create several spiroid winglet shapes, and numerically tested their relative aerodynamic efficiency. It is found that indeed this winglet is aerodynamically beneficial, and further acoustic excitation effects and improvments are also included.
