The invention belongs to the technical field of aircraft take-off control, and particularly relates to a columnar vortex generator for improving the backflow characteristic of a bias plate. The columnar vortex generator (1) comprises a fixed end (11) connected with the root of a ship platform (2) or a drift plate (3), a first extension section (12) is formed by extending from the fixed end (11) to the position above the ship platform (2), a second extension section (13) extends from the tail end of the first extension section (12) to the direction close to the drift plate (3), and the tail end of the second extension section (13) is bent inwards to form a third extension section (14). The distance between the position, closest to the flow deflecting plate (3), of the third extending section (14) and the flow deflecting plate (3) is set to be 10-30 cm. 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柱状涡流发生器。所述柱状涡流发生器(1)包括与船舶平台(2)或偏流板(3)根部连接的固定端(11),自固定端(11)向船舶平台(2)上方延伸形成第一延伸段(12),在所述第一延伸段(12)的末端向靠近偏流板(3)方向延伸有第二延伸段(13),所述第二延伸段(13)末端向内弯曲形成第三延伸段(14);所述第三延伸段(14)的最靠近偏流板(3)的位置与所述偏流板(3)的距离设定为10‑30cm。本申请能够有效阻挡回流,大幅度减小回流的吸入风险。
