The invention belongs to the technical field of aircraft take-off control, and particularly relates to a backflow baffle for improving the backflow characteristic of a bias plate. The backflow baffle (1) is arranged between a bias plate (3) of a ship platform (2) and an aircraft body, one side of the backflow baffle (1) is hinged to the ship platform (2) through a rotating shaft, the other side of the backflow baffle (1) is a movable side, the backflow baffle (1) can rotate around the rotating shaft so as to be switched between an open state and a closed state, and in the closed state, the backflow baffle (1) is closed. The upper surface of the backflow baffle (1) is flush with the plate face of a ship platform, in the open state, the backflow baffle (1) and the ship platform (2) form a set angle, the height of the movable side of the backflow baffle (1) is smaller than that of an airplane spraying pipe, and the distance between the movable side and the flow deflecting plate (3) is a set distance. 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回流挡板。该回流挡板(1)设置在船舶平台(2)的偏流板(3)与飞机机体之间,所述回流挡板(1)一侧通过转轴铰接在船舶平台(2)上,另一侧为活动侧,所述回流挡板(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,回流挡板(1)上表面同船舶平台的板面齐平,在打开状态,回流挡板(1)与船舶平台(2)成设定角度,回流挡板(1)的活动侧高度低于飞机喷管,且活动侧与偏流板(3)的间距为设定距离。本申请能够有效阻挡回流,大幅度减小回流的吸入风险。
