Abstract

La présente invention concerne un aéronef à décollage et atterrissage verticaux (VTOL), comprenant un corps (120), au moins deux unités rotatives (130) accouplées au corps, chacune présentant un arbre rotatif (131) et une pale (135), ainsi qu'un carter (201) couvrant le corps et les unités rotatives et présentant des ouvertures (201a). Le carter (201) peut présenter une forme de conduit présentant une ouverture destinée à recevoir l'unité rotative à l'intérieur, ou peut présenter une paroi latérale (203) destinée à entourer la pale. Chaque ouverture (201a) peut présenter un moyen de protection (207). Les couples de réaction des unités rotatives peuvent s'équilibrer sans nécessiter de dispositif d'équilibrage séparé. Le carter couvre les pales, empêchant ainsi la génération de portance non équilibrée sur les pales rotatives, contrairement aux hélicoptères classiques, lorsque l'aéronef VTOL vole en avant. De plus, étant donné que les unités rotatives ne peuvent entrer en contact avec des articles extérieurs, l'aéronef empêche la rupture des unités rotatives et les dommages aux articles extérieurs. Du fait d'une caractéristique structurelle du carter, la poussée permettant de propulser l'aéronef VTOL peut être augmentée d'environ 10 ~ 15 %. En outre, une gouverne de direction (301) est montée dans le carter, permettant ainsi à l'aéronef VTOL de voler librement en lacet ou de voler en avant et en arrière selon l'orientation de la gouverne de direction.
