The invention belongs to the technical field of aircraft take-off control, and particularly relates to a root baffle for improving the backflow characteristic of a bias plate. The root baffle (1) is arranged on the side, facing an aircraft body, of a bias plate (3), one side of the root baffle (1) is hinged to the bias plate (3) through a rotating shaft, the other side of the root baffle (1) is a movable side, the root baffle (1) can rotate around the rotating shaft so as to be switched between an open state and a closed state, in the closed state, the root baffle (1) is folded to the bias plate (3), and in the closed state, the root baffle (1) is folded to the bias plate (3). The upper surface of the root baffle (1) is flush with the plate face of the flow deflecting plate (3), a set angle is formed between the root baffle (1) and the flow deflecting plate (3) in the opening state, and the height of the movable side of the root baffle (1) is smaller than that of the aircraft nozzle. Backflow can be effectively blocked, and the suction risk of the backflow is greatly reduced.

    本申请属于飞机起飞控制技术领域,特别涉及一种改善偏流板回流特性的根部挡板。该根部挡板(1)设置在偏流板(3)的朝向飞机机体的一侧,所述根部挡板(1)一侧通过转轴铰接在偏流板(3)上,另一侧为活动侧,所述根部挡板(1)能够绕所述转轴转动以在打开状态与关闭状态切换,在关闭状态,根部挡板(1)折叠到偏流板(3)上,其上表面同偏流板(3)的板面齐平,在打开状态,根部挡板(1)与偏流板(3)成设定角度,根部挡板(1)的活动侧高度低于飞机喷管的高度。本申请能够有效阻挡回流,大幅度减小回流的吸入风险。
