The utility model relates to a glider technical field discloses an overhead paddle glider under water, including roudnel shape casing, the inside of roudnel shape casing is equipped with rotational system, roudnel shape casing outer fringe is equipped with the fixed baffle that is equipped with mutual symmetry in below of ring, ring. The ring sets up in the outer fringe of roudnel shape casing, further reduces the resistance that the glider glided, thus when the glider need change the navigation direction, change navigation direction that can be rapid, in addition, the ring below is equipped with the baffle of mutual symmetry, not only reduces the resistance coefficient of glider, and when changing course the direction, the baffle can form the surface of water scope of a similar tornado moreover, and the surface of water that produces the large tracts of land separates to guarantee that the glider can be in the stability after the wide -angle is turned. The utility model discloses simple structure, convenient to use, the appearance is novel. Can make the glider under the prerequisite of the advantage of good maneuverability, reduce the influence of wave, avoid the phenomenon of drifting with the tide, reach the effect that improves the speed of a ship or plane.
