Abstract

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.

Description

technical field [0001] The invention relates to a vector thrust device, in particular to a ducted vector thrust device. Background technique [0002] With the rapid development of UAV technology in the world, a large number of fixed-wing UAVs and multi-axis rotor UAVs have appeared. The take-off and landing of fixed-wing UAVs requires a certain sliding distance, has strict requirements on the runway, has limited maneuverability, and cannot achieve ultra-low-speed cruise. Although the multi-axis rotor UAV can take off and land vertically, it has disadvantages such as slow flight speed, short range, low flight altitude, and poor survivability. So far, the take-off and landing methods of existing UAVs have great limitations, and cannot cope well with various emergencies. How to effectively improve the take-off and landing performance and maneuverability of UAVs has become an urgent problem to be solved. [0003] At present, the United States and Russia use thrust vectoring t...
