The invention belongs to the field of hard airfoil sails, and relates to a novel hard airfoil sail with an airflow suction function. A novel hard wing-shaped sail with an airflow suction function is characterized by comprising a sail body (100); an end plate (1) is arranged on the upper end face of the cylindrical part of the sail body (100); one side wall of the sail body (100) is a sail body convex surface (101), and the other side wall of the sail body (100) is a sail body concave surface (102); an air suction hole (3) is formed in the sail body convex surface (101); an exhaust hole (5) is formed in the end plate (1); airflow entering from the suction hole (3) is exhausted from the exhaust hole (5); and the air suction holes (3) are arranged at intervals along the horizontal and vertical directions of the sail body concave surface (102). The novel hard wing-shaped sail with the airflow suction function is simple in structure, long in service life, convenient to maintain and high in safety and reliability, the thrust effect of the hard wing-shaped sail can be remarkably improved, and then the energy-saving efficiency is greatly improved.

    本发明属于硬质翼型风帆领域,涉及一种具备气流抽吸功能的新型硬质翼型风帆。具备气流抽吸功能的新型硬质翼型风帆,其特征在于:包括,帆体(100);帆体(100)筒状部件的上端面设置有端板(1);帆体(100)的侧壁:一面为帆体凸面(101),一面为帆体凹面(102);帆体凸面(101)上设置有吸气孔(3);端板(1)上设置有排气孔(5);从吸气孔(3)进入的气流从排气孔(5)中排出;吸气孔(3)沿帆体凹面(102)水平及竖直方向间隔设置。本发明的具备气流抽吸功能的新型硬质翼型风帆结构简单,使用寿命长,维修方便,安全可靠性高,能显著提升硬质翼型风帆的推力效果,进而大大提升节能效率。
