Description

  The present invention relates to a ring wing flying toy, and more particularly to a ring wing flying toy characterized in that a ring wing flying body composed of a single ring wing is caused to fly stably and at a long flight distance.

  In general airplanes, air resistance due to vortices (wing tip vortices) generated at the wing tips is a major problem. In order to solve this problem, it is effective for reducing the air resistance to make the wing as long as possible like a glider, but there is another problem of strength. Therefore, a method of reducing the air resistance by attaching a winglet (vertical small wing (plate) for reducing the vortex) to the wing tip without changing the length of the wing is performed. By the way, when both ends of the blade are connected, there is no end, and as a result, the air resistance due to the blade tip vortex is eliminated and the overall air resistance is greatly reduced. Theoretically, the air resistance of the ring wing projectile is reduced by 50% from the plane end. Paper airplanes using this ring wing are known (see, for example, Non-Patent Document 1 and Non-Patent Document 2).
