Abstract

Véhicule comprenant un hydrofoil mobile (6) relié à une structure porteuse (2) par un dispositif limiteur d'effort (8) adapté pour appliquer une précontrainte permanente à l'hydrofoil pour le maintenir en position nominale tant qu'il ne subit pas un effort supérieur à une limite prédéterminée non nulle supérieure à un effort de sustentation moyen nécessaire pour sustenter la structure porteuse, et permettre à l'hydrofoil de se déplacer vers une position effacée lorsqu'il subit un effort supérieur à cette limite prédéterminée, tout en sollicitant l'hydrofoil vers sa position nominale avec une force comprise entre 1 et 2 fois la limite prédéterminée.

Figure imgaf001
Vehicle comprising a mobile hydrofoil (6) connected to a supporting structure (2) by a force-limiting device (8) adapted to apply a permanent prestress to the hydrofoil to maintain it in nominal position as long as it does not undergo a force greater than a predetermined non-zero limit greater than an average buoyancy force necessary to sustain the bearing structure, and allow the hydrofoil to move to an erased position when it experiences a force greater than this predetermined limit, while requesting the hydrofoil to its nominal position with a force between 1 and 2 times the predetermined limit.
