Research progress of test technologies for 3 m×2 m icing wind tunnel

The 3 m×2 m icing wind tunnel was built in 2013. A lot of progresses have been made in the research of the wind tunnel test technologies in recent years. This paper presents the basic situations and test technologies of the 3 m×2 m icing wind tunnel, including overall situation, technical indexes and test capabilities. The status of the conventional icing and anti-icing test technologies in the 3 m×2 m icing wind tunnel, such as the calibration of cloud parameters, the capture of ice characteristics, the anti-icing technology using hot air and the de-icing technology using electrics are described in detail. From the view of engineering application and basic research, the research trend of test technologies in the fields of aircraft engines, helicopters, supercooled large droplets (SLD), and ice crystals are highlighted and analyzed. The development ideas and methods are put forward from the perspective of independent innovation. This paper provides a reference for the research on the construction and test technology development for the icing wind tunnel.
