Abstract

La présente invention concerne un système de transport aérien multifonctionnel constitué : d'un dirigeable hybride modulaire manœuvrable (1) de longueur variable et comprenant une nacelle de transport modulaire (4) et des rotors de levage électriques (15) intégrés dans deux paires d'ailes à incidence variable (17), fixées, respectivement, à un module de nez (20) et à un module de queue (21) ; et une tour d'accostage (2) extensible en hauteur et comprenant une plate-forme d'atterrissage rotative (8), et un mécanisme d'amarrage (3) comprenant un bras extensible (26) et un mât d'amarrage (25). Ensemble, ces éléments forment un concept unique pour le transport de personnes et/ou de marchandises, y compris leur embarquement/chargement et débarquement/déchargement.
