ABSTRAKT

General models and methods for examining the icing processes of airfoils, as well as the corresponding meteorological parameters, types of clouds, and ice, are analyzed. Techniques for estimating ice growth in typical flight conditions are considered. The model of interpenetrating media and the trajectory model (inertial model of droplets precipitation) are used to describe moisture precipitation on the streamlined surface. The results of calculating the icing of a cylinder and an airfoil in viscous compressible air-droplet flow, taking into account the form of existence of moisture on the airfoil and the mode of ice accretion, are presented.
