The presence of aircraft icing significantly impacts the flow over airfoils with flaps. Icing on airfoils leads to aerodynamic performance penalties, including reduced lift, increased drag, and altered critical angles of attack. The formation of ice on airfoils can result in changes in the lift coefficient by up to 37% and drag coefficient by up to 107%, depending on the icing conditions. Additionally, the presence of ice alters the flow characteristics, affecting the angle of attack and the position of ice accumulation on the airfoil. Understanding these effects is crucial for designing effective ice protection systems to mitigate the negative impact of icing on airfoil performance and ensure safe and efficient operation of aircraft, especially in challenging icing conditions.
