...Antoine Faye; Paolo Perali; Benoit Augier; Matthieu Sacher; Jean-Baptiste Leroux; Alain Nême; Jacques-André Astolfi _ In this paper, the hydroelastic response of a NACA0015 composite hydrofoil is studied experimentally and numerically. The foil is made of composite materials with fibers not aligned...

...Hugo Nicolas; Paolo Perali; Matthieu Sacher; Patrick Bot _ The use of hydrofoils to enhance ship performance raises the scientific issue of free-surface proximity, which is important to consider during the design stage, to feed velocity prediction programs, for instance. Typically, the flow over...

...Rafael Tannenberg; Stephen R. Turnock; Karsten Hochkirch; Stephen W. Boyd Hydrofoils are a vital part of modern racing yachts such as the AC75, which was sailed in the 36th America’s Cup and should hence be optimised thoroughly. The literature shows that hydrofoil design and optimisation usually...

...Paul Francois; Basile Lère; Xavier Amandolese; Jacques-André Astolfi Strong correlation between boundary layer excitation and hydrofoil eigenmode occurs for specific angles of attack and Reynolds numbers, resulting in strong tonal noise emissions under certain circumstances. This study aims...

...Sakir Bal Curved tip effect on the performance of three-dimensional (3-D) cavitating hydrofoils moving steadily under a free water surface has been investigated numerically by an iterative boundary element method (IBEM) developed before. The IBEM has been modified and extended to solve this problem...

... presents numerical simulations of a 2D hydrofoil section NACA0012 at 5° angle of attack in the vicinity of the free-surface, for different values of the submergence depth, for a chord-based Froude number of 0.571 and a Reynolds number of 159,000. Unsteady-Reynolds Averaged Navier-Stokes (URANS) equations...

... with the VPP based hydrofoil design, considering the sailing performance in three modes: displacement, transition and hydrofoil. The yacht is a lightweight monohull designed for light wind conditions with up to five crew members. The design includes a self-stabilizing hydrofoil configuration and an elevator...

...Thilo Keller; Juryk Henrichs; Karsten Hochkirch; Andres Cura Hochbaum Hydrofoil supported sailing vessels gained more and more importance within the last years. Due to new processes of manufacturing, it is possible to build slender section foils with low drag coefficients and heave stable hydrofoil...
