Research progress on construction strategy and technical evaluation of aircraft icing accretion protection system

The impact of unstable supercooled water droplets suspended in the cloud on the solid will cause its surface to freeze, and the flight safety of the aircraft will be seriously affected when flying in this environment. Aircraft icing protection system is an important device to reduce icing accidents and improve aircraft safety performance, which is of great significance to ensure flight safety. Based on the energy source, this paper proposes a general strategy for constructing an aircraft icing protection system, including Active Anti-icing and De-icing (AAD) system, Passive Anti-icing and De-icing (PAD) system and Composite Anti-icing and De-icing (CAD) system. The principle, scope of application, advantages and disadvantages of aircraft anti-icing and de-icing technologies such as electric pulse de-icing, low-frequency piezoelectric de-icing, and hydrophobic material anti-icing are explored in detail, and the corresponding improvement measures are proposed. The future development of aircraft anti-icing and de-icing technology is prospected, and some new ideas are provided for the improvement of aircraft anti-icing and de-icing technology.
