The invention belongs to the technical field of aircraft take-off control, and particularly relates to a bias plate capable of improving the backflow characteristic. When the bias flow plate (1) is in an open state, a plurality of bosses (3) extending in the width direction are formed on the side, facing an airplane, of the bias flow plate (1), the boss (3) located at the highest position is located on the lower edge of tail jet flow jetted by an airplane tail jet pipe in the height direction, and a strip-shaped groove used for guiding airflow to flow back is formed between every two adjacent bosses (3). The open state of the bias plate (1) means that the bias plate (1) is placed on the ship platform (2) from a horizontal state to a vertical state forming a certain angle with the ship platform (2), and is placed behind an aircraft to be takeoff, so that the aircraft is boosted to take off by means of the counter-acting force of jet flow at the tail of the aircraft. 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,特别涉及一种能够改善回流特性的偏流板。所述偏流板(1)在打开状态下,其朝向飞机的一侧上形成有多个沿宽度方向延伸的凸台(3),其中位于最高处的一个凸台(3)在高度方向上位于飞机尾喷管喷射的尾喷流的下边沿,相邻凸台(3)之间形成有用于引导气流回流的条形槽,所述偏流板(1)的打开状态是指所述偏流板(1)在船舶平台(2)上由平放状态至与船舶平台(2)呈一定角度的竖起状态,并置于待起飞飞机的后方,以借助飞机尾喷流的反作用力助推飞机起飞。本申请能够有效阻挡回流,大幅度减小回流的吸入风险。
