Abstract
Icing phenomenon is an important problem in helicopter rotor design. Conducting experiments in a cold chamber is one of the main methods used to study the law of rotor icing. The purpose of this paper was to analyze the influence of different parameters on the ice shapes of rotor blade and to obtain the relationship between the ice shapes and the input parameters. The icing experimental platform of rotation blade in a cold chamber was set up, and the rotor icing experiments under various conditions were carried out. The ice shapes on the blade were obtained, and the influence of different icing temperatures, rotation speeds, liquid water content, icing times, number of blades on the rotor, and blade materials on the ice shapes were analyzed. The results showed that the ice thickness on the leading edge increased with the increase of liquid water content, rotation speed, and icing time, and the number and material of blades had little effect on icing. The conclusions of this paper can provide a reference for the rotor numerical simulation and future experimental research.

Summary
With the development of modern helicopters, all-weather flight is one of the most important goals that is being pursued by the new generation of helicopters worldwide. The main methods of helicopter rotor icing research include experimental research and numerical simulation [3,4], and the experimental research includes flight experiments and ground experiments. Flight experiment is generally used as the last method in airworthiness certification to verify the performance of rotor anti-icing and de-icing systems. Sci. 2020, 10, 5884 overcome the shortcomings of flight experiment and icing wind tunnel experiment, the rotor icing experimental platform is usually built in the cold environment, such as McKinley climate laboratory in the United States, where full-scale helicopter rotor icing experiments can be carried out [10,11]. Snow & Ice Management Association (SIMA) icing wind tunnel and compared them with flight test results. The experimental results were analyzed and the effects of different parameters on rotor icing were obtained. The research results of this paper can be compared with the numerical simulation of rotor icing, providing support for further research and verification of anti-icing and de-icing systems design
