Numerical studies of the flow around the slotted mechanized wing and morphing wing of a mainline aircraft in real flight conditions

The results of numerical studies on the effect of gaps in wing mechanization during landing in icing conditions are presented. It is shown that a morphing wing, within the range of small angles of attack, is less susceptible to the negative influence of icing. Additionally, its ice accretions do not significantly alter the shape of the airfoil compared to a slotted mechanized wing. Numerical studies were conducted using a numerical code based on the Reynolds-averaged Navier–Stokes equations.
