Abstract

Appareil à effet de sol équipé de systèmes équipés de surfaces planantes immergées aussi nommées foils ou hydrofoils, et qui fournissent une poussée verticale au décollage comme à l’atterrissage. Le dispositif selon l’invention permet de limiter d’une part les effets de la traînée hydrodynamique et d’autre par de limiter les vibrations induites par les chocs de l’appareil (coque, fuselage, ailes, flotteurs) avec la surface de l’eau. Selon les variantes du dispositif il est constitué de surfaces planantes ou hydrofoils (15) et de mécanismes de rétractation si les hydrofoils sont destinés à être mobiles. Une variante particulière permet de transformer l’hydrofoil (15) en dispositif de réduction de traînée aérodynamique (17) par un mécanisme de rotation (16). Figure de l’abrégé: Figure 8
