Abstract

L'invention concerne une coque de navire à grande vitesse comportant un flotteur principal central (2) et deux flotteurs latéraux de longueur plus courte, situés vers l'arrière du flotteur central, reliés à celui-ci par des bras de liaison et comportant des ailerons immergés, les bras de liaison étant carénés en forme d'ailes créant deux tuyères à effet de sol entre les surfaces latérales intérieures émergées respectives du flotteur central et des flotteurs latéraux, et la surface liquide sur laquelle se déplace la coque du navire, la coque comprenant en outre des moyens (16, 17, 18) au niveau de l'étrave (2a) du flotteur central (2) pour prélever de l'eau en bas de l'étrave et l'injecter vers l'avant du flotteur central au-dessus de la surface liquide sur laquelle se déplace la coque du navire afin de créer une émulsion air/eau sur le bas de l'étrave diminuant la traînée de frottement.The invention relates to a high-speed ship's hull comprising a central main float (2) and two lateral floats of shorter length, located towards the rear of the central float, connected to the latter by link arms and comprising submerged fins, the link arms being streamlined in the form of wings creating two ground effect nozzles between the respective emerged inner side surfaces of the central float and side floats, and the liquid surface on which the ship's hull moves, the hull further comprising means (16, 17, 18) at the bow (2a) of the central float (2) for taking water from the bottom of the bow and injecting it forward of the float central above the liquid surface on which the ship's hull moves in order to create an air / water emulsion on the bottom of the bow reducing the frictional drag.
