| dc.description.abstract | Sailboats and dinghies have been ”foiling” for a long time now, but they all face the same problems with stability when losing the righting moment of the hull when it leaves the water. Chalmers Formula Sailing team’s idea to use split flaps, which can be used to control the centre of lift is a new way to tackle this problem. This report investigates possible concepts for controlling a split flap system mechanically. The proposed solution to this problem is a linkage system transferring a signal from the water surface to the flap of the foil to control the height at which the boat flies. It includes an axial cam which can be customized to enhance the foiling performance of the boat with respect to both stability and speed. This solution shows significant improvements compared to the concept previously suggested to Formula Sailing. This report shows that a split flap system can be controlled in many ways with benefits and deficits to each concept, however the concept suggested is the best option with respect to performance, durability and adjustability. The outcome gives a clear picture of how this concept can be implemented into the existing design with important design features pointed out. Further work will include engineering on other areas to complete the full concept, such as hydrodynamics and structures of the foil itself. Important delimitations have been made regarding the detail level of the parts included in the system, detailed fatigue calculations and economical aspects. | sv |
