Title
(EN) MOTORISED AIRPLANE WITH MIXED HYDRODYNAMIC AND AERODYNAMIC STRUCTURE FOR TAKE-OFF AND LANDING ON WATER, GROUND OR SNOW
(FR) AVION MOTORISÉ A STRUCTURE MIXTE HYDRODYNAMIQUE ET AÉRODYNAMIQUE POUR LE DÉCOLLAGE ET L'ATTERRISSAGE SUR L'EAU, LE SOL OU LA NEIGE
Abstract
(EN)
A motorised airplane includes a landing gear (17) with at least two legs (21) capable of retracting into the fuselage (11) via hatches (28). A pair of hydrofoils (16) is fitted to the base of the fuselage (11) in conformance with the ailerons used for lift and hydrodynamic stability, directed towards the base like a reverse V shape. The legs (21) of the landing gear (17) are each articulated around the pivot axes (20), fitted onto the hydrofoils (16). The landing gear (17) is dual-function, using wheels (18) or skis (19) suspended on legs (21). Applications: airplane for landing on water, ground and snow.

Un avion motorisé comporte un train d'atterrissage (17) ayant au moins deux jambes (21) rétractables dans le fuselage (11) à travers des trappes (28). Une paire d'hydrofoils (16) est agencée à la base du fuselage (11) en étant conformés selon des ailerons de portance et de stabilisation hydrodynamique, dirigés vers le bas selon un V renversé. Les jambes (21) du train d'atterrissage (17) sont articulées chacune autour d'axes de pivotement (20) agencés sur les hydrofoils (16). Le train d'atterrissage (17) est mixte en faisant usage de roues (18) ou de skis (19) portés par les jambes (21). Applications : avion à atterrissage sur l'eau, la terre et la neige.
