The aircraft aerodynamic characteristics are directly dependent on their geometry, in particular, on the wing airfoil. The airfoil can change significantly in-flight due to the growth of ice, which can impact effectiveness of the airfoil. Accounting for this phenomenon is a multidisciplinary task that requires an appropriate solution, making it relevant for design calculations. The process of obtaining an ice-covered surface of the aircraft using the performed calculation of the external aerodynamics problem is described in this paper. The shape and geometry, as well as the ice effect on the aerodynamic characteristics are examined. Various arrangements are considered, both for the aircraft as a whole and for the wing separately, with engine nacelle traditionally mounted on a pole under the wing. Several flight modes at different altitudes in clouds of non-uniform phase composition (water and mixed) with particles of different diameter are considered. This work is part of the compiled methods of designing a polymer composite wing using parametrical modeling at the design analysis stage.
