The invention belongs to the technical field of aircraft take-off control, and particularly relates to an active jet device for improving the backflow characteristic of a bias plate. The active jet device (1) comprises a drainage cavity (11), the drainage cavity (11) is provided with a jet inlet (12) and a jet outlet (13), and the drainage cavity and the jet inlet (12) are connected with a high-pressure air source which is used for providing high-pressure air with set pressure for the jet inlet (12); the active jet flow device (1) is arranged on the ship platform (2) and located on one side of the backflow section, a jet flow outlet (13) of the active jet flow device (1) right faces the backflow section and is used for jetting jet flow parallel to the bias flow plate (3) to the backflow section, and the backflow section is the area between the bias flow plate (3) and an aircraft body. 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主动射流装置。所述主动射流装置(1)包括引流腔(11),引流腔(11)具有射流入口(12)及射流出口(13),所述引流腔,射流入口(12)连接有高压气源,用于向射流入口(12)提供设定压力的高压空气;所述主动射流装置(1)设置在船舶平台(2)上,且位于回流区间的一侧,主动射流装置(1)的射流出口(13)正对所述回流区间,用于向所述回流区间喷射平行于偏流板(3)的射流,所述回流区间为偏流板(3)与飞机机体之间的区域。本申请能够有效阻挡回流,大幅度减小回流的吸入风险。
