Unmanned aerial vehicle

A control method of an unmanned aerial vehicle, comprising:

• generating a plurality of jet streams which flow to lateral guiding outlets of the unmanned aerial vehicle to generate a propulsion;
• wherein from a first quadrant to a fourth quadrant, the jet streams are a first jet stream, a second jet stream, a third jet stream and a fourth jet stream, respectively,
• wherein, when the propulsion generated by the first jet stream and the second jet stream is smaller than the propulsion generated by the third jet stream and the fourth jet stream, the unmanned aerial vehicle tilts towards a first direction on a side of the vehicle body having a smaller propulsion, such that the jet streams eject in a direction oblique to the gravity direction of the unmanned aerial vehicle and drive the unmanned aerial vehicle to move horizontally along the first direction;
• when the propulsion generated by the first jet stream and the second jet stream is greater than the propulsion generated by the third jet stream and the fourth jet stream, the unmanned aerial vehicle tilts towards a second direction on another side of the vehicle body having a smaller propulsion, such that the jet streams eject in a direction oblique to the gravity direction of the unmanned aerial vehicle and drive the unmanned aerial vehicle to move horizontally along the second direction inverse to the first direction;
• when the propulsion generated by the first jet stream and the second jet stream is equivalent to the propulsion generated by the third jet stream and the fourth jet stream, the unmanned aerial vehicle hovers,
• wherein the jet streams are generated by a pressure centrifugal impeller pressurizing an inlet gas passing through an airflow inlet of the unmanned aerial vehicle in a direction parallel to an axial direction of an center hub of the unmanned aerial vehicle to flow towards a radial direction of the center hub.
