Abstract

La présente invention concerne un hélicoptère hybride (10) comportant un fuselage (11), un rotor principal (12), deux ailes (15) situées de part et d'autre dudit fuselage (11) et deux hélices de propulsion (13) situées respectivement sur une aile (15). Chaque hélice de propulsion (13) est inclinée et génère lors de sa rotation une force de poussée (Fd,Fg) selon un axe de poussée (Pd,Pg) incliné par rapport à une direction longitudinale (X) dudit hélicoptère hybride (10). De la sorte, une composante longitudinale et une composante transversale de ladite force de poussée (Fd,Fg) de chaque hélice de propulsion (13) génèrent respectivement, au cours d'un vol stationnaire dudit hélicoptère hybride (10), un couple se combinant pour former un moment (Mstat) s'opposant à un couple en lacet (CR) dudit hélicoptère hybride (10).
