The test capability of AEDC and CIRA icing wind tunnel are analyzed. The present situation of building the icing wind tunnel and that of icing test in China are analyzed. The measurements of the important parameters of liquid water content (LWC) and the water droplets median volume diameter (MVD) are researched. In numerical simulation aspect, four parts of icing numerical calculation are summarized, the virtues and defects of different methods are compared. At last, the development trend of the research for icing on aircraft engine is put forward based on the current research actualities.
