Abstract

a. L'invention concerne un dispositif moteur pour hélicoptères équipés de deux moteurs à turbines à gaz disposés parallèlement l'un à côté de l'autre, la puissance prélevée sur l'arbre de chaque turbine de puissance utile étant utilisée pour entraîner le rotor. b. Ce dispositif est caractérisé en ce que les turbines de puissance utile sont disposées chacune suivant le même angle d'inclinaison par rapport à l'axe longitudinal du moteur associé et de manière telle que les axes longitudinaux de ces turbines ou leurs prolongements coupent le plan de symétrie longitudinal de l'hélicoptère, ainsi que l'axe vertical du mécanisme d'entraînement du rotor ou de ce rotor lui-même, en un même point. c. L'invention est applicable à l'entraînement des rotors d'hélicoptères.at. The invention relates to an engine device for helicopters equipped with two gas turbine engines arranged parallel to one another, the power taken from the shaft of each useful power turbine being used to drive the rotor. b. This device is characterized in that the turbines of useful power are each arranged at the same angle of inclination with respect to the longitudinal axis of the associated engine and in such a way that the longitudinal axes of these turbines or their extensions intersect the plane of longitudinal symmetry of the helicopter, as well as the vertical axis of the rotor drive mechanism or of this rotor itself, at the same point. vs. The invention is applicable to the drive of helicopter rotors.
