Abstract

L'invention concerne une coque de navire à grande vitesse comportant un flotteur principal central (2) et deux flotteurs latéraux (3) de longueur plus courte, situés vers l'arrière du flotteur central, reliés à celui-ci par des bras de liaison (4) 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 (20) sur laquelle se déplace la coque du navire, la coque comprenant en outre des moyens (16, 18) pour prélever des gaz d'échappement provenant d'un moteur de propulsion (10b) et les injecter vers l'arrière sous chaque bras de liaison afin d'augmenter le rendement de l'effet de sol.
