The invention relates to a high-performance marine airfoil sail structure with a tail rotor and a front suction part. The high-performance marine airfoil sail structure comprises an airfoil main body, the tail rotor is arranged at the tail edge of the airfoil main body; the negative-pressure gas collecting chamber is arranged at the front edge of the airfoil-shaped main body; wherein the number of the negative pressure gas collecting chambers is two, the two negative pressure gas collecting chambers are symmetrically arranged, and the negative pressure gas collecting chambers are used for sucking gas and restraining low-speed separation flow above the wing section under the large attack angle. The sharp tail edge of the airfoil-shaped body is changed into the movable tail rotor, the air collecting chamber is arranged on the front edge of the airfoil-shaped body, the air suction holes are formed in the two symmetrical positions of the upper portion and the lower portion of the airfoil-shaped body, the airfoil-shaped stall angle is greatly delayed, the lift force extreme value of the airfoil-shaped sail is remarkably increased, and the airfoil-shaped sail is simple in structure, convenient to machine and low in cost. And automatic control of opening and closing of air suction and intensity change at each wind direction angle can be easily realized through a control and monitoring system.

    本发明涉及一种带尾部转子和前部抽吸的高性能船用翼型风帆结构,包括翼型主体;尾部转子设置在翼型主体的尾缘;负压集气室设置在翼型主体的前缘;其中,负压集气室设置有两个,两个负压集气室对称设置,通过负压集气室吸气,用于抑制大攻角下翼型上方的低速分离流。本发明将翼型主体尖锐的尾缘改成活动的尾部转子,并在翼型主体的前缘设置集气室,通过在翼型主体上下方的两个对称位置处布置吸气孔实现翼型失速角的大幅延后,并且显著增加了翼型风帆的升力极值,结构简单,加工方便,且容易通过控制和监测系统实现各风向角下吸气的开闭以及强度变化的自动化控制。
