摘要：
In order to deeply understand the influence of rotor icing, the characteristics of rotor icing and its main corresponding factors were described from icing intensity and icing shedding from the tip part. Then the aerodynamic influences of icing on helicopter lift resistance, hovering and control characteristics were summarized, and the probable ideas of evaluating rotor ice shedding on helicopter physical damage were proposed. Main technologies in the application of rotor anti-/de-icing, such as electrothermal anti/de-icing, fluids anti-icing and pneumatic de-icing, were introduced, and their advantages and disadvantages were systematically analyzed. Concretely, electrothermal anti-/de-icing had high efficiency, but high energy consumption. Liquids anti-icing had low energy consumption, but short functional time and low anti-icing efficiency. Although the pneumatic de-icing system had low energy consumption, its installation position was limited, making it easy to cause aerodynamic losses of helicopters. On this basis, focus was put on the shortcomings of the current helicopter anti-/de-icing system, the important problems to be solved in the future development of anti-/de-icing were comprehensively prospected from the aspects of high-precision prediction of rotor icing, coupling development of various icing systems, and large-area preparation of super hydrophobic materials. © 2023 BUAA Press.
