The utility model discloses an airplane flap, belongs to the field of airplane high lift systems, and is used for reducing side edge noise of the flap and controlling aerodynamic loss at the same time. According to the main technical scheme, the aircraft flap does not comprise an actuating structure for providing air jet, the aircraft flap comprises at least one side edge opening, and the side edge opening is connected with one or more air passages and used for leading in and/or leading out air flow to reduce the strength of a flap side edge vortex system structure. The air passage penetrates through the first surface and the second surface of the flap, a first side edge opening is formed in the first surface, a second side edge opening is formed in the second surface, one of the first surface and the second surface is a side surface of the flap, and one of the first side edge opening and the second side edge opening is a side surface opening. The aircraft flap can reduce pneumatic loss while guaranteeing the noise reduction effect, and is simple in structure and high in practicability.

    本专利公开了一种飞机襟翼,属于飞机高升力系统领域,用于降低襟翼侧缘噪声,同时控制气动损失。本发明的主要技术方案为:一种飞机襟翼,不包括提供空气射流的致动结构,所述飞机襟翼包括至少一个侧缘开口,所述侧缘开口连接一个或多个空气通路,用于引入和/或引出气流来降低襟翼侧缘涡系结构强度,所述空气通路贯穿所述襟翼的第一表面和第二表面,在第一表面上形成第一侧缘开口,在第二表面上形成第二侧缘开口,所述第一表面和所述第二表面其中之一为襟翼的侧表面,所述第一侧缘开口和第二侧缘开口其中之一为侧表面开口。此种飞机襟翼可以在保证降噪效果的同时减小气动损失,而且结构简单,实用性强。
