Abstract

An unmanned aerial vehicle according to the present invention may comprise: a rotor-blade for providing thrust according to generation of main stream; and a safety guard disposed to surround the rotor-blade. The safety guard may comprise: a guide member which is disposed coaxially with the rotor-blade while having a gap between the guard member and the end of the rotor-blade, so as to stabilize, when the rotor-blade rotates, a flow field suctioned by a negative pressure, and stably boost a discharge flow when the pressure is changed to a positive pressure; and a diffuser which is disposed coaxially with and radially spaced apart from the guide member, and generates a secondary flow toward the main stream to increase a flow rate.

Description

technical field [0001] Various embodiments of the present disclosure relate to an unmanned aerial vehicle including safety guards. Background technique [0002] Unmanned aerial vehicles (UAVs), which have been used for military purposes, are rapidly being introduced into the fields of communication relay, traffic control, and logistics. Additionally, the market for unmanned aerial vehicles is expanding rapidly, and so are the related laws. [0003] Regulations related to unmanned aerial vehicles control unlicensed flying in no-fly areas and commercial photography using unmanned aerial vehicles not registered with the Flight and Aviation Administration. [0004] In recent years, interest in the safety of unmanned aerial vehicles has increased. To prevent the increased risk of injury to persons around the unmanned aerial vehicle due to high speed rotation of the rotor blades (which may occur due to inexperienced pilots during takeoff and landing), and to prevent Damage caus...
