Abstract:
The results of a numerical study of the effect of temperature changes on ice formation on a straight wing with an asymmetric profile are presented. The results of calculating the effect of ice on the aerodynamic characteristics of the wing show that ice formed at the angle of attack 2$^\circ$ practically does not affect the lift and pitch moment, but has a negative effect on the drag and aerodynamic quality of the wing. An analysis of the results of calculating the weight of the growing ice showed that for an aircraft wing, depending on its aerodynamic profile, there is an optimal angle of attack – from the point of view of the minimum weight of ice build-up and the optimal angle of attack of ice build-up, the shape of which has a minimal effect on its aerodynamic characteristics.
