Abstract:

Icing will seriously affect the flight performance of helicopters and threaten their flight safety. The rotor is the main component of helicopters affected by icing, and how to carry out rotor anti-icing and de-icing with low energy consumption and high efficiency is an urgent problem for helicopters. Unlike that of fixed wings, rotor icing has a more complex flow field, and many anti-icing and de-icing technologies that perform well on fixed wing aircraft cannot be directly used on helicopter rotors. The characteristics and main response factors of rotor icing are introduced firstly, and the impact of icing on the aerodynamic performance of helicopters is summarized. Then, the principles, advantages and disadvantages, and scope of application of existing anti-icing and de-icing technologies are emphasized. The advantages of composite anti-icing and de-icing technologies represented by electrothermal-mechanical and electrothermal coating technologies are discussed in detail. Suggestions for the subsequent development of helicopter rotor anti-icing and de-icing are proposed. This article has certain significance for promoting the development of helicopter rotor anti-icing and de-icing technologies.

Key words: helicopter, rotor icing, electric anti-icing and de-icing, mechanical deicing, hybrid anti-icing and de-icing
