Title
(EN) LIFTING FORCE REGULATED HYDROFOIL
(FR) AILE PORTANTE RÉGULÉ PAR FORCE DE PORTANCE
Abstract
(EN) The claims describe a hydrofoil performance control system for waterborne vessels where the vessels weight is wholly or partially supported by fully or partially submerged hydrofoil or foils, and where the amount of lift provided by said foils is regulated as a function of that lift. A typical control system comprises one or more sensory inputs, a method or function to translate the input into a control output, and an actuator that turns the outputs into actual movements. In this invention the control input is the lifting force currently being produced by the hydrofoil. The movement output is the movement necessary to regulate the lifting force in response to the input as defined by the functional relationship between input and output. The invention combines the three elements of the basic control system into a single mechanical resistive element, where a resistive element is one that opposes the force applied to it and where said force produces a movement within said resistive element. The precise characteristics of said mechanical resistive element determine the functional mapping between the control input and the control output. Said mechanical resistive element may operate in compression, tension, or torsion depending on the precise mechanical arrangement used to support said hydrofoil(s). The movement produced in said mechanical resistive element is used to provide the control output movement through mechanical coupling that changes the lift produced by said hydrofoil by altering its angle of attack. The performance of the mechanical resistive element may be adjusted to change the overall performance of the control system.
(FR) Les revendications décrivent un système de commande de performance d'aile portante pour des navires à l'eau où le poids des vaisseaux est entièrement ou partiellement supporté par des ailes ou ailes portantes totalement ou partiellement immergées, et où la quantité de portance fournie par lesdites ailes est régulée en fonction de cette portance. Un système de commande classique comprend une ou plusieurs entrées sensorielles, un procédé ou une fonction pour traduire l'entrée en une sortie de commande, et un actionneur qui fait tourner les sorties en déplacements réels. Selon la présente invention, l'entrée de commande est la force de portance actuellement produite par l'aile portante. La sortie de déplacement est le déplacement nécessaire pour réguler la force de portance en réponse à l'entrée telle que définie par la relation fonctionnelle entre l'entrée et la sortie. L'invention combine les trois éléments du système de commande de base en un seul élément résistif mécanique, un élément résistif étant un élément qui s'oppose à la force appliquée à celui-ci et ladite force produisant un déplacement dans ledit élément résistif. Les caractéristiques précises dudit élément résistif mécanique déterminent le mappage fonctionnel entre l'entrée de commande et la sortie de commande. Ledit élément résistif mécanique peut fonctionner en compression, en tension ou en torsion en fonction de l'agencement mécanique précis utilisé pour supporter ladite(lesdites) aile(s) portante(s). Le déplacement produit dans ledit élément résistif mécanique est utilisé pour fournir le déplacement de sortie de commande par l'intermédiaire d'un couplage mécanique qui modifie la portance produite par ladite aile portante en modifiant son angle d'attaque. Les performances de l'élément résistif mécanique peuvent être ajustées pour modifier les performances globales du système de commande.
