Jet-propelled vertical take-off and landing unmanned aerial vehicle capable of realizing thrust vector control

The invention relates to a jet-propelled vertical take-off and landing unmanned aerial vehicle capable of realizing thrust vector control, which comprises a step-shaped rack, engine mounting racks are symmetrically connected to two ends of the rack, turbojet engines are symmetrically mounted at two ends of the engine mounting racks, and nozzles of the turbojet engines face the outer side of the rack. The tail portions of the nozzles of the turbojet engines are connected with arc-shaped spray pipes capable of rotating by +/-30 degrees, and the arc-shaped spray pipes are used for achieving vector flow guiding of thrust of the turbojet engines. Compared with the prior art, the turbojet engines serve as a power source, the rotation of the arc-shaped spray pipes is controlled through a steering engine and a four-bar mechanism, and therefore airflow is guided to achieve thrust vector control, and the load capacity and maneuverability of the aircraft can be effectively improved. According to the aircraft, the overal
