The invention discloses an airborne lightweight dual-channel circulation control unit, and the unit at least comprises two independent jet flow channels which share a middle wall surface. Each jet flow channel at least comprises an air source inlet, a transition section, a rectification section and a jet flow outlet, the air source inlets of the two jet flow channels are designed in a crossed and staggered mode, the axes of the air source inlets are located in the same plane and pass through the center line of the Coanda profile, reverse external thread design is adopted, and the transition section is a round channel to rectangular channel. A boss is arranged on the side face, away from the other jet flow channel, of an outlet of the transition section, a pressure sensor and a temperature sensor are arranged on the boss, flow direction reinforcing ribs are arranged in the rectification section, and the adjacent reinforcing ribs are of an intermittent staggered structure and used for rectification and structural reinforcement of the jet flow channels. The weight and the size of the structure are reduced as much as possible under the condition that the structural safety is met, and the outer profile of the tail end of the circular rector control unit and the outer profile of the rear edge of the wing are seamlessly combined and are positioned and fixed on an aircraft through net-shaped supports on the two sides.
本发明公开了一种机载轻量化双通道环量控制单元,所述环量控制单元至少包括两个独立的射流通道,共用中间的壁面;所述射流通道至少包括气源入口、过渡段、整流段和射流出口,所述两个射流通道的气源入口采用交叉错位设计,气源入口轴线在同一平面内,且经过柯恩达型面的中线,采用反向外螺纹设计,所述过渡段为圆形通道转矩形通道,在过渡段出口侧面,远离另一个射流通道一侧有一个凸台,凸台上布置有压力传感器和温度传感器,所述整流段内布置有流向加强肋,相邻加强肋采用断续错位结构,用于射流通道的整流和结构加强,在满足结构安全的情况下尽量降低结构的重量和体积,环量控制单元尾端外型面与机翼后缘外型面无缝结合,并通过两侧的网状支架定位并固定在飞机上。
