MOTORIZED AEROPLANE WITH HYBRID HYDRODYNAMIC AND AERODYNAMIC STRUCTURE FOR TAKING OFF AND LANDING ON WATER, THE GROUND OR SNOW

摘要

An aeroplane includes a fuselage having a pair of hydrofoils providing hydrodynamic lift and stabilization arranged downwards in the form of an inverted V. The junction between each hydrofoil and the fuselage is situated forward from the centre of gravity of the aeroplane. The distance separating the junction between each hydrofoil and the fuselage, with respect to the centre of gravity of the aeroplane is comprised between 0 and 170% of the mean aerodynamic chord of the main wing of the aeroplane, preferably between 20% and 135%. Each hydrofoil is inclined downwards, from its leading edge in the direction of its trailing edge. The straight line connecting these two edges form, a nominal pitch angle comprised between 2 and 12°, preferably between 6 and 8°. The part of the hydrofoil located beneath the tangential plane is situated forward from the centre of gravity.
