Ice shedding from the rotating components can cause unacceptable mechanical damage to the engine intake system. Therefore， it is necessary to study the phenomenon of rotating deicing. The ice shedding research can be divided into two parts i.e.， experimental study in the icing wind tunnel and numerical simulation based on the finite element software. The ice shape， mass and density are obtained through experiments under different conditions. The stress distribution of ice on a solid surface is obtained by simulation. The experimental results show that the rime ice formed at a lower temperature is more difficult to lose than the glaze ice formed at a higher temperature. The simulation results show that the cohesion strength of the rime ice is less than its shear adhesion， but the cohesion strength of the glaze ice is greater than its shear adhesion.
