Abstract�� In order to study the prediction of ice accretion on helicopter rotor, a theoretical rotor icing model was founded based on the computational fluid dynamics (CFD) technique by analyzing the theory of ice accretion and helicopter flight. Euler two-phase flow theory was used in solving the governing equations corresponding to droplets, and a modified model of the mass and heat transfer on ice surface was proposed based on the classical Messinger model. The method of prediction of ice shape on rotor was analyzed detailedly by using UH-60 and CH-47 as examples, and they can lay the foundation of the research about the helicopter dynamics in the icing condition and the design of anti/de-ice system. The result shows that the method has positive significance of improving the flight safety performance of helicopter.
Keywords�� rotor icing   prediction of ice accretion   numerical simulation   thermodynamic model
