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

The optimization of CP contours results in a shock-free, single-point optimization with elliptical distribution. We conducted extensive research on various configurations, including full configurations for aircraft. This experience led us to explore applications in other areas, such as wind turbines and hydrofoils. Our collaboration with American Magic began when they reviewed our research papers and reached out to us for assistance. I emphasized the importance of approaching problems gradually, even when they appear straightforward. We initiated our work by analyzing 2D sections of the T-foil, which is crucial for generating lift.

In our design efforts, we also examined the rudder, although I will not discuss that aspect here. It is important to note that the design considerations for hydrofoils differ from those for aircraft wings. When evaluating the drag polar, it is essential to adopt a different perspective. Specifically, we aim to elevate the drag polar to achieve a lower takeoff speed.
