Features of the formation of ice creations on a symmetrical and asymmetrical airfoil and their influence on aerodynamic characteristic of the wing

The results of numerical investigations ice formations on the wing with symmetrical and asymmetrical airfoil. Numerical studies ice creations were carried out on straight wing in the range of angles of attack from -$20$ degrees to $20$ degrees in conditions of experiment in aerodynamic tube with number Mach $\mathrm{M}=0.12$ and Reynolds $\mathrm{Re}=0.7\cdot10^6$ million. Compare aerodynamic characteristic of the wing without ice, obtain in calculations with experimental results are presented. Analysis of the results of ice formations is performed.
