The invention relates to a marine airfoil sail structure based on a circular rector control technology, which comprises an airfoil main body, the tail edge of the airfoil main body is circular, and the airfoil main body comprises a jet flow acting section, and a jet flow inlet section and an end sealing section which are arranged at the two ends of the jet flow acting section; the at least two runners are arranged on the wing-shaped main body at intervals; each flow channel comprises a jet flow inlet, a gas collection chamber and a jet flow outlet which are communicated with one another; the jet inlet is formed in the jet inlet section, the gas collection chamber is arranged in the jet action section, and the jet outlet is formed in the upper surface of the jet action section; at least one jet outlet is arranged above the trailing edge of the airfoil-shaped main body, and the height of the jet outlet is h; the radius of the trailing edge of the airfoil main body is r; the chord length of the airfoil main body is c; if so, h/c is more than 0.05 and less than 0.25, and r/c is more than 0.02 and less than 0.05. Lift force can be improved, the stall angle can be delayed, then sail propelling power is enhanced, and the sail can adapt to wind direction changes of larger angles.
本发明涉及一种基于环量控制技术的船用翼型风帆结构,包括翼型主体,其尾缘为圆形,翼型主体包括射流作用段、及设置在射流作用段两端的射流入口段和端部封口段;至少两个流道间隔设置在翼型主体上;其中,每个流道包括相互连通的射流入口、集气室和射流出口;射流入口设置在射流入口段,集气室设置在射流作用段中,射流出口设置在射流作用段上表面;至少一个射流出口设置在翼型主体的尾缘上方,且该射流出口的高度为h;翼型主体尾缘的半径为r;翼型主体的弦长为c;则,0.05<h/c<0.25和0.02<r/c<0.05。本发明能够提高升力,延迟失速角,进而增强风帆推进的功率,并有利于适应更大角度的风向变化。
