Description

Technical Field

[0001] The utility model relates to the technical field of automatic anti-icing control for unmanned aerial vehicles, and more specifically to an automatic anti-icing control device for unmanned aerial vehicles. Background Art

[0002] When a drone is flying in the atmosphere, ice is likely to form on its wings under low temperature and humid conditions. Ice may cause adverse effects such as increased airfoil drag, reduced critical angle of attack, and decreased lift-to-drag ratio. In severe cases, it may cause flight safety accidents with disastrous consequences.

[0003] There are three main methods of anti-icing. The first is to turn on the power, which uses the electric heater to generate heat to raise the temperature. When the temperature is high, it will not freeze. This is the most widely used method. The second is to pass hot air, which is drawn from the engine and continuously circulates in the anti-icing cavity in the wing. This technology has requirements on the structural design of the aircraft. The third is to spray antifreeze, which lowers the freezing point after mixing with water, but it is not suitable for aircraft with large size and long flights.

[0004] Traditional UAV anti-icing systems need to obtain wing temperature information from a ground station before sending heating channel control instructions to the UAV. If the communication between the UAV and the ground station is interrupted, a flight accident is likely to occur when the wings are frozen. Utility Model Content
