Unmanned aerial vehicle deicing system, deicing method and unmanned aerial vehicle

Abstract

The application discloses a UAV deicing system, deicing method and UAV. The UAV deicing system includes a liquid-cooled engine, a heating mechanism, a deicing heating circuit and a cooling liquid power device, wherein the heating The mechanism is located on the wing of the UAV. The liquid-cooled engine has a coolant passage surrounding the cylinder. The deicing heating circuit communicates with the cooling liquid passage and the heating mechanism. The coolant of the liquid-cooled engine circulates in the deicing heating circuit. In this way, the coolant absorbs heat from the liquid-cooled engine, and transfers the heat to the heating mechanism, thereby heating the wings, thereby preventing the wings of the UAV from icing, and solving the problem of the UAV flying at high altitude. The technical problem of the risk of icing on the wings has achieved the technical effect of improving the safety of UAVs flying at high altitudes.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle deicing technology, in particular to an unmanned aerial vehicle deicing system, a deicing method and an unmanned aerial vehicle. Background technique [0002] UAV is a kind of aircraft. When the UAV is flying at a high altitude, due to the influence of the atmospheric environment, the surface of the UAV may freeze, and the icing of the wings especially affects flight safety. Therefore, UAVs usually need to have a deicing system when flying at high altitudes. [0003] However, in UAVs using piston liquid-cooled engines as power devices, due to the limitation of the output power of the piston engine, it cannot meet the power requirements of the electrothermal deicing power of the aircraft wing, and the piston engine does not have a large flow of high-temperature gas. Therefore, UAVs using a piston liquid-cooled engine as a power plant usually do not have a deicing system. When the UAV flies a...

Problems solved by technology

[0003] However, in UAVs using piston liquid-cooled engines as power devices, due to the limitation of the output power of piston engines, it cannot meet the power requirements of electric heating deicing for aircraft wings, and the piston engines do not have a large flow of high-temperature gas. Therefore, UAVs using a piston liquid-cooled engine as a power plant usually do not have a deicing system. When the UAV flies at high altitudes, there is a risk of icing on the wings, which seriously affects its high-altitude flight. Safety
