Abstract

L'invention concerne un aéroglisseur propulsé par roue à aubes qui comprend une coque (1), un système d'alimentation, un système de tenue stationnaire et un système de propulsion. Ledit système de tenue de stationnaire comprend un ventilateur de tenue stationnaire (10) et un tablier (3). Ledit système de propulsion comprend une paire d'hélices de roue à aubes (2) qui sont disposées symétriquement sur les deux côtés horizontaux d'une partie centrale longitudinale du fond de la coque (1) et qui sont situées sur le côté intérieur du tablier (3). La direction de déplacement desdites hélices de roue à aubes (2) est la même que celle de la coque. Le bord inférieur desdites hélices de roue à aubes (2) est inférieur au bord inférieur du tablier (3). Lesdites hélices de roue à aubes (2) sont disposées au fond de la coque (1) au moyen d'un support d'élévation et leur hauteur peut être réglée. Par comparaison avec les aéroglisseurs classiques pouvant être en vol stationnaire intégralement, ledit aéroglisseur propulsé par roue à aubes présente une efficacité de propulsion supérieure, est moins bruyant, tout en offrant de meilleures exploitabilité et stabilité.
