The invention discloses a wing-shaped rowlock and a racing boat, and belongs to the field of racing boats. The wing-shaped paddle frame and the racing boat comprise a main paddle frame, and a connecting frame connected with paddles is arranged at one end of the main paddle frame. The upper end face of the main paddle frame is a first arc-shaped face, and the lower end face of the main paddle frame is a first plane. The cross section of the main paddle frame is in a wing shape. In the advancing process, the air velocity of the first arc-shaped surface is larger than that of the first plane surface, then the pressure intensity of the upper end face of the main paddle frame is smaller than that of the lower end face of the main paddle frame, and the main paddle frame bears upward thrust. The pressure intensity of the upper surface and the lower surface of the main rowlock is changed, the main rowlock is subjected to upward thrust in the advancing process, then the whole racing boat is subjected to upward thrust, the advancing resistance of the racing boat is reduced, and an athlete obtains a better score.
本发明公开了一种翼型桨架及赛艇,属于赛艇领域。一种翼型桨架及赛艇,包括主桨架,所述主桨架一端设置有与桨叶相连的连接架。所述主桨架上端面为弧形的第一弧形面,下端面为第一平面;所述主桨架的横截面呈“翼型”。行进时,第一弧形面表面的空气流速大于第一平面表面的空气流速,进而主桨架上端面的压强小于主桨架下端面的压强,主桨架受到向上的推力。改变主桨架上下表面的压强,让主桨架在行进过程中受到向上的推力,进而赛艇整体受到向上的推力,减轻赛艇行进的阻力,让运动员取得更好的成绩。
