Problems solved by technology

The oil-powered UAV of the prior art is equipped with four independent engines, and the airflow interference between adjacent rotors is difficult to resolve, and increasing the distance between the engines will further increase the volume and weight
[0006] The above-mentioned oil-powered UAVs in the prior art are equipped with an oil-powered engine on each cantilever. The exposed engine and the noise of the rotor make it almost impossible for the UAV to be used in urban airspace, and it cannot be used in a military environment. what concealment
The balance of cantilever length a

Embodiment Construction

[0024] 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.

[0025] As mentioned above, most of the existing oil-powered UAVs adopt a fully symmetrical layout, resulting in the center of gravity being concentrated at one point, and the load layout is greatly restricted, and because the fully symmetrical rotors block all directions of the UAV, resulting in The carried load cannot launch weapons or observe obliquely upwards, which limits the application range of existing drones. In addition, there is airflow interference between adjacent rotors. Extending the length of the cantilever will increase the weight of the whole machine, and the ability to carry payloads is greatly limited.

[0026] In order to solve the above-mentioned def...

Abstract

The invention relates to an oil-driven unmanned aerial vehicle landing gear which is used under an oil-driven unmanned aerial vehicle body. The oil-driven unmanned aerial vehicle body has a longitudinally symmetrical axis. The landing gear comprises two identical arched pieces and two identical cross bars, the arched pieces are respectively arranged on the lower parts of an unmanned aerial vehiclehead and an unmanned aerial vehicle tail, the arched pieces respectively have a structure symmetrically relative to the symmetrical axis, and the tail ends of the two arched pieces positioned on thesame side of the symmetrical axis are connected with one cross bar. The arched pieces of the landing gear adopts a symmetrical structure, and are connected as a whole leftward and rightward, and therefore, the landing gear on the two sides of the unmanned aerial vehicle really has a structure connected as a whole, and the landing gear with the integrated structure has reinforcement performance, sothat a special structure for reinforcing a connecting point of the landing gear does not need to be arranged on the unmanned aerial vehicle body, the structure weight of the unmanned aerial vehicle is lightened, and the load level of the unmanned aerial vehicle is improved.

Description

technical field [0001] The 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 landing gear structure applicable to the 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 usually ...
