The invention belongs to the technical field of aerospace, and particularly relates to a binary thrust vector control surface, an upper wall, two side walls, a lower wall and a nozzle of an aircraft, a nozzle channel is defined by the upper wall, the two side walls and the lower wall, the nozzle is arranged in the nozzle channel, the lower wall comprises a fixed bearing section and a vector control surface hinged to the fixed bearing section, and the vector control surface is arranged in the nozzle channel. The vector control surface is driven by a connecting rod mechanism to deflect up and down and located behind an engine tail nozzle, and the efficiency of the control surface can be effectively improved through engine jet injection. The installation position is located at the tail of the aircraft, the farther from the center of gravity is, efficient control surface efficiency can be obtained through a long force arm, and the course control capacity of layout is improved. Meanwhile, a certain distance is reserved from the engine, the temperature is reduced to about 200 DEG C and is far away from the ultra-high-temperature environment, the service life is prolonged, and the design difficulty and the use cost are reduced.

    本申请属于航空航天技术领域,特别涉及一种飞机的二元推力矢量舵面,上壁、两侧壁、下壁以及喷口,上壁、两侧壁、下壁围成喷口通道,喷口置于所述喷口通道中,其中,下壁包括固定承载段以及铰接在固定承载段上的矢量舵面,矢量舵面通过连杆机构驱动上下偏转,位于发动机尾喷口后面,可有效利用发动机喷流引射提高舵面效率;安装位置位于飞机尾部,离重心越远,可通过较长力臂获得高效的舵面效率,提高布局的航向操纵能力。同时离发动机有一定距离,温度降低到200°左右,远离超高温环境,提升使用寿命,降低设计难度和使用成本。
