Abstract

The invention relates to an unmanned aerial vehicle icing protection device comprising wings, a heat conduction device and a heating device. The outer walls of the wings are covered with skins, and anti-icing cavities are formed in the wings. The heat conduction device comprises an engine compressor, a flow limiter, a one-way valve and anti-icing valves, and the anti-icing valves are arranged on the wings. The heating device comprises icing sensors, electric heating layers and pulse devices which are connected sequentially. According to the unmanned aerial vehicle icing protection device, heatof an engine and the electric heating and pulse devices are mixed for deicing, the advantages of the heat of the engine and the electric heating and pulse devices are combined, a good icing protection effect is formed, namely it is guaranteed that no ice layer exists nearby important parts such as stagnation points at the front edges of the wings, damage of icing to the aerodynamic shape of a vehicle is also reduced, and the power consumption of the vehicle is reduced.

Description

technical field

[0001] The invention belongs to the technical field of aircraft, and in particular relates to an icing protection device for an unmanned aerial vehicle. Background technique

[0002] The icing protection system is one of the important systems related to the flight safety of the aircraft. At present, the hot air anti-icing system and the electric thermal anti-icing system are commonly used. The protected aircraft surface includes the leading edge of the wing (tail), helicopter blades, engine Intake leading edge, etc. These two system solutions are relatively mature in technology and have been widely used in military and civilian aircraft. UAVs generally undertake reconnaissance or attack missions. In the mission profile, when they encounter icing weather environments, they need icing protection. System to ensure flight safety, the wing is the main lifting surface, but also the main icing protection surface. If a conventional hot gas anti-icing system or an e...
