The invention belongs to the field of air flow, and relates to a blowing flap of a fixed-axis fixed sub-flap self-adaptive spoiler. Comprising a fixed wing surface, a fixed rotating shaft, a main flap, a sub-flap, a main flap blowing seam, a sub-flap blowing seam, a spoiler rotating shaft and a spoiler, the main flap and the sub-flaps are downwards deflected by a large angle, meanwhile, the spoilers are downwards deflected to be attached to the upper surfaces of the sub-flaps, and the air blowing seams in the sub-flaps and the main flap work according to a certain air blowing quantity coefficient matching relation, so that the maximum lift coefficient of the aircraft is greatly improved, meanwhile, the ultra-high lift-drag ratio is achieved, and the super-circular effect is achieved.
本发明属于空气流领域,涉及一种定轴固定子襟翼自适应扰流板的吹气襟翼。包括固定翼面、固定转轴、主襟翼、子襟翼、主襟翼吹气缝、子襟翼吹气缝、扰流板转轴、扰流板;采用主襟翼和子襟翼大角度下偏,同时扰流板下偏至其与子襟翼上表面贴合,子襟翼和主襟翼上的吹气缝以一定的吹气动量系数匹配关系进行工作,大幅度提高飞行器的最大升力系数,同时具有极高的升阻比,实现超环量效应。
