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
In addition, the existing gasoline-powered UAV basically does not consider the heat dissipation problem when the engine is built in, and often can only rely on the way of increasing the opening of the fuselage for passive heat dissipation, resulting in a lot of noise for the oil-powered UAV. At the same time, because there is no Effective heat dissipation design can easily cause the entire fuselage to be heated to form a huge and eye-catching infrared target, which is easy to be found and shot down

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 provides a heat dissipation structure for an oil-driven unmanned aerial vehicle, the heat dissipation structure is used for being mounted on a fuselage (1) of the unmanned aerial vehicleand conducting heat dissipation on an engine (99), wherein the heat dissipation structure comprises a radiator (100) arranged above the tail part of the fuselage (1); and a heat dissipation cavity ofthe radiator (100) is connected with a cooling water tank of the engine (99) through an upper water pipe (101) and a lower water pipe (102), the cooling water tank is mounted in the fuselage (1), andthe cooling water tank is provided with a circulating water pump. According to the heat dissipation structure for the oil-driven unmanned aerial vehicle, through the radiator arranged outside the fuselage, heat of the engine arranged in the fuselage is dissipated out in a forced water cooling mode by using circulating cooling water, so that a large heat dissipation opening is not required to be formed in the fuselage of the unmanned aerial vehicle, noise of the engine can be well shielded by the fuselage, stealth performance of the unmanned aerial vehicle is improved, and detectability of theunmanned aerial vehicle is reduced.

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 heat dissipation structure for 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 usually electri...
