Embodiment Construction

[0067] In one embodiment of the present invention, a kind of unmanned aerial vehicle is proposed, in order to produce a plurality of jet streams that control flight direction, the body center of the unmanned aerial vehicle of this embodiment only has single airflow propeller, so that blade or rotor It will not be exposed outside the body, so it is safer. Compared with the traditional quadrotor aircraft, which has four rotors and four motors, it is heavier, and the four rotors are exposed outside the body, which is easy to hurt people or things around. The unmanned aerial vehicle invented can avoid the lethality generated when the rotor rotates at high speed.

[0068] In one embodiment of the present invention, the propelling forces of the jets in each outlet direction may be equal or unequal. For example, under the condition that the propulsive force of the jet stream in each exit direction is equal, when the propulsive force produced by the jet stream is greater than the grav...

Abstract

The invention provides a UAV (unmanned aerial vehicle). The UAV comprises a vehicle body and an airflow propeller, wherein the vehicle body is provided with a central propeller boss, an airflow guide structure and an outer ring body, the inside of the airflow guide structure communicates between the central propeller boss and the outer ring part, the central propeller boss is provided with an airflow inlet, the outer ring part is provided with a plurality of side guide outlets correspondingly facing the gravity direction of the UAV, the airflow propeller is arranged in the central propeller boss and used for producing multiple jet airflows, so that the multiple jet airflows flow to the plurality of side guide outlets through the airflow guide structure to produce propelling force.

Description

technical field [0001] The invention relates to an aircraft, in particular to an unmanned aircraft. Background technique [0002] In recent years, unmanned aerial vehicle (Unmanned Aerial Vehicle, referred to as UAV) has received extensive attention and reports. In addition to using drones for aerial photography, it can be especially used in disaster relief, exploration, delivery and other occasions. The market for UAVs is unstoppable as UAVs become less expensive, more people use them, and have more recreational or commercial applications. [0003] However, recent news often reports incidents of unmanned aerial vehicles falling and causing injuries. Therefore, safety problems caused by unmanned aerial vehicles must be prevented as soon as possible. In addition, how to reduce the weight of the body and the number of rotors is also one of the problems to be solved urgently. Contents of the invention [0004] The object of the present invention is to provide an unmanned a...
