Design Optimization of Subcavitating Hydrofoils for America's Cup Class Yachts

The last condition we are examining is a maneuver condition. In this scenario, the aircraft slows down while also requiring high lift to facilitate turning, necessitating an increased lift coefficient (CL) of approximately 1.3.

Now, let’s focus on the optimization process. We are plotting the shape of the airfoil alongside the flap angle. It is important to note that while the airfoil shape remains constant across all conditions, the flap angle varies for each specific condition.
