Patent

CA 2075043

A VTOL aircraft including a fuselage (10) with four nacelles (12, 14, 16, and 18), three vertical stabilizers (20, 22, and 24) and a horizontal stabilizer (26) attached to the fuselage (10). The fuselage (10) and the nacelles (12, 14, 16, and 18) are lifting bodies that are configured to jointly form an aerodynamic lifting body which cooperates with the horizontal stabilizer (26) to provide aerodynamic lift to the aircraft in forward flight. Each nacelle contains two rotary engines (60 and 62) directly driving corresponding fans (64 and 66) which face each other and operate in counter- rotating directions. Each nacelle (12, 14, 16, and 18) also contains a system of vanes (82) located at the rear opening (58) thereof, and devices for extending and retracting the vanes (82). A triple redundant computerized flight control system maintains the stability of the aircraft as it transitions from one flight regime to another as well as in flight.

Avion à décollage et à atterrissage verticaux comprenant un fuselage (10) présentant quatre nacelles (12, 14, 16 et 18), trois stabilisateurs verticaux (20, 22 et 24) ainsi qu'un stabilisateur horizontal (26) fixés au fuselage (10). Le fuselage (10) et les nacelles (12, 14, 16 et 18) sont des corps de sustentation configurés pour former conjointement un corps de sustentation aérodynamique coopérant avec le stabilisateur horizontal (26) afin de donner à l'avion une sustentation aérodynamique en vol vers l'avant. Chaque nacelle contient deux moteurs rotatifs (60 et 62) entraînant directement des soufflantes correspondantes (64, 66) se faisant face mutuellement et fonctionnant dans des sens de contre-rotation. Chaque nacelle (12, 14, 16 et 18) contient également un système d'aubes (82) situé au niveau de son ouverture arrière (58), ainsi que des dispositifs destinés à étendre et à rétracter les aubes (82). Un système de commande de vol informatisé à triple redondance maintient la stabilité de l'avion lorsqu'il passe d'un régime de vol à un autre, ainsi qu'en vol.
