Aerodynamic Characteristics of Multi-Element Iced Airfoil – CFD Simulation
Keywords:
aerodynamics, aircraft icing, performance degradationAbstract
The phenomenon of the in-flight icing can affect all types of aircraft. Presence of the ice accretion on wings can lead to performance degradation. Thus, it is important to understand how the different ice shapes affect aerodynamic characteristics. The prediction of the ice accretion on the wing with flaps of different position was made by the in-house code ICE 4.1. The two-dimensional CFD simulation was used for the study of aerodynamic performance degradation of multi-element iced airfoil. The results are discussed and some of them are compared with the wind tunnel testing.
