Abstract

La présente invention concerne un aéronef capable de décoller verticalement, plus spécifiquement un dispositif capable de décoller verticalement sans l'aide de rotors. Outre un moteur, une boîte de vitesses et un ventilateur, le dispositif décrit dans cette invention comprend deux ensembles de panneaux sur les côtés gauche et droit conçus pour barrer le vent, lesquels ensembles définissent une structure en forme de demi tunnel aérodynamique. Le ventilateur est contenu dans ce tunnel. L'ensemble de volets est fixé le long du sens d'écoulement. Chaque volet est monté de manière rotative sur les panneaux de barrage du vent et chaque volet est disposé de haut en bas le long du sens de circulation de l'air. L'ensemble de volets est pourvu d'un mécanisme de réglage de l'angle d'attaque. La caractéristique de l'ensemble de volets est d'atteindre une valeur égale ou supérieure à CL/CD ≈ 20 ? 5. Le dispositif décrit dans cette invention consiste en une nouvelle combinaison de finesse aérodynamique, et il peut permettre un décollage et un atterrissage verticaux à une vitesse de croisière nulle et il peut atteindre une distance de croisière R≥ 1600km.
