Actuation and Retraction of Foils

This lecture presents a Bachelor's project on the actuation and retraction of foils for the next Swiss boat on Lake Geneva. The project involved researching mechanisms, testing old technologies on the lake, and aiming to transport three passengers at 25 knots autonomously. The focus was on electric and hydraulic actuation of flaps, with challenges in selecting the right motors and dealing with weight constraints. The goal was to retract the foils quickly for easy maneuvering in the port, exploring various actuation methods. The project required extensive research and engineering skills, although the ideal mechanism was not found.
