Abstract | Disclosed are an improved nozzle for an unmanned underwater vehicle (UUV), and a method for operating the same. The nozzle includes a first rigid member operatively coupled to a UUV steering mechanism. The nozzle also has a second rigid member, coupled to the first rigid member by a flexible bellows according to a configurable operating angle. The nozzle does not extend beyond a bounding surface when stored but does when deployed. Water traversing the first rigid member and contacting the second rigid member produces a reactive force according to the configurable operating angle. Simultaneous and independent control of the volume of fluid traversing several such nozzles in the UUV, and their respective orientations and operating angles, permits automatic station-keeping or navigation according to another guidance objective.
L'invention concerne une buse améliorée destinée à un véhicule sous-marin sans pilote (UUV), et son procédé de fonctionnement. La buse comprend un premier élément rigide accouplé de manière fonctionnelle à un mécanisme de direction d'UUV. La buse comporte également un second élément rigide, accouplé au premier élément rigide au moyen d'un soufflet flexible selon un angle de fonctionnement configurable. La buse ne s'étend pas au-delà d'une surface de délimitation lorsqu'elle est stockée mais s'étend au-delà de ladite surface lorsqu'elle est déployée. L'eau traversant le premier élément rigide et venant en contact avec le second élément rigide produit une force réactive en fonction de l'angle de fonctionnement configurable. Le réglage simultané et indépendant du volume de fluide traversant plusieurs de telles buses dans l'UUV et leurs orientations et angles de fonctionnement respectifs permettent un maintien en position ou une navigation automatiques selon un autre objectif de guidage. |
