Oil-driven unmanned aerial vehicle landing gear

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 ...

AI Technical Summary

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 and weight makes the choice of oil-powered engines very small, the power of each engine cannot be too large, the lift is limited, and the ability to carry payloads is greatly limited

In addition, the landing gear of the above-mentioned oil-powered UAVs in the prior art has both a mounting function, which makes it difficult to dismantle and reduce the volume of the UAV. At the same time, due to the need to consider mounting, the structural weight of the landing gear increases, making The dead weight of the UAV is too large, and the carrying capacity of the load is greatly limited
