Abstract
(EN)
The present invention provides a VTOL aircraft with tilt front rotors. A front wing bearing the front rotors is provided on the front fuselage and a main wing is provided below the rear rotors that locate on the rear fuselage. This arrangement makes the disc area of rear rotor bigger than those of two front rotors, and the area ratio of front wing and main ring is substantially corresponding to the lift ratio of front rotor and rear rotor. Thus, front wing can bear the same lift produced by front rotor and reduce the load of main wing, which makes the wing arrangement and the distribution of lift more reasonable and improves the cruise flight efficiency.

La présente invention concerne un aéronef à décollage et atterrissage verticaux à rotors avant basculants. L'avant du fuselage est équipé d'une voilure avant portant les rotors avant, et d'une voilure principale monté en dessous des rotors arrière situés sur l'arrière du fuselage. Cet agencement fait que le disque rotor des rotors arrières est supérieur au disque rotor des rotors avant, et que le rapport d'aire de la voilure avant et de la voilure arrière correspond sensiblement au rapport de portance entre rotor avant et rotor arrière. Ainsi, la voilure avant peut supporter la même portance produite par le rotor avant et réduire la charge de la voilure principale, ce qui rend la disposition des voilures et la distribution de la portance plus raisonnable et améliore le rendement en vol de croisière.
