Embodiment Construction

[0026] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings. Wherein, the same parts adopt the same reference numerals.

[0027] As described in the background, the present invention aims at the deficiencies of the oil-powered quadrotor UAV disclosed in the prior art Chinese patent application 201711089265.3, and proposes an improved structure so that the shroud of the UAV of the prior art With a more optimized structure and weight, a lighter structural weight can be obtained at the same time, and the shape is simpler, which can further reduce the shape resistance.

[0028] Specifically, the fuselage bearing structure of the oil-powered drone of the present invention is a further improvement proposed on the basis of the oil-powered quadrotor drone of 201711089265.3. This prior art is cited i...

Abstract

The invention provides a supporting structure of a fairing for an oil-driven unmanned aerial vehicle. The supporting structure comprises a first supporting rod, a second supporting rod and a third supporting rod which extend outwards from a transmission seat of a rotor wing of the unmanned aerial vehicle radioactively, wherein the first supporting rod is arranged along the extending direction of acantilever; the second supporting rod and the third supporting rod are respectively arranged in a manner of being vertical to the first supporting rod; the first supporting rod, the second supportingrod, the third supporting rod and the cantilever are arranged to support the fairing from the bottom part of the fairing. The supporting structure provided by the invention has the beneficial effectsthat the supporting structure of the fairing supports the fairing from the bottom part of the fairing, the supporting point of the supporting structure is positioned under the fairing, so that the opening of the connecting part is positioned under the fairing and can not cause interference with the flow field in the fairing basically, the adverse influence of the supporting structure on the airflow efficiency of the rotor wing is reduced, the pneumatic structure of the flow guiding channel can not be damaged and the flow guiding effect is better.

Description

technical field [0001] The present invention relates to the technical field of unmanned aerial vehicles, in particular to a multi-rotor oil-powered unmanned aerial vehicle, and in particular to a supporting structure for a shroud of an oil-powered unmanned aerial vehicle. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft controlled by radio remote control equipment and its own program control device. According to the application field, UAV can be divided into military and civilian. In terms of military use, UAVs are divided into reconnaissance aircraft and target aircraft. Civilian drones are widely used in aerial photography, agriculture, plant protection, micro-selfies, express delivery, disaster relief, observation of wild animals, monitoring of infectious diseases, surveying and mapping, news reports, power inspections, disaster relief, film and television shooting and other fields. [0003] Existing multi-rotor drones are u...
