Bypass type vector thrust device suitable for small unmanned aerial vehicle

Abstract

本发明涉及一种矢量推力装置,具体涉及一种涵道式矢量推力装置。适用于小型无人机的涵道式矢量推力装置,其技术方案是,它包括:用于产生气流的推力产生装置、用于改变气流方向的矢量喷管组件以及导流装置;推力产生装置为涵道风扇(1);导流装置包括:管道(4)以及安装在管道(4)前后两端的圆形固定环(2)、方形固定环(6);矢量喷管组件包括:舵机(8)、转盘(12)以及尾喷口(10);本发明通过控制转向器的旋转实现尾喷口的上下偏转,不仅可以实现小型无人机的垂直起降、悬停,还可以保证在无人机作低速、大攻角状态机动飞行,甚至在操纵舵面几近失效时利用矢量推力提供额外操纵力矩来控制无人机正常飞行。
The invention relates to a vector thrust device, in particular to a bypass type vector thrust device. The bypass type vector thrust device is suitable for small unmanned aerial vehicles, and adopts the technical scheme that the bypass type vector thrust device comprises a thrust generation device, a vector nozzle assembly and a flow guide device, wherein the thrust generation device is used for generating air flow, the vector nozzle assembly is used for changing the direction of the air flow, the thrust generation device is a bypass fan (1), the flow guide device comprises a pipeline (4), circular fixing rings (2) and square fixing rings (6), the circular fixing rings (2) and the square fixing rings (6) are arranged at the front and back ends of the pipeline (4), and the vector nozzle assembly comprises a rudder (8), a turntable (12) and a tail nozzle port (10). The bypass type vector thrust device has the advantages that the vertical deflection of the tail nozzle port is realized by controlling a steering device to rotate, the vertical landing and takeoff and the hovering of the small unmanned aerial vehicle are realized, and the unmanned aerial vehicle is guaranteed to realize maneuvering flight at low speed and large angle of attack, and is controlled to normally fly by utilizing the vector thrust to provide additional operation torque when the operation of rudder surface nearly fails.
