Abstract

L'invention concerne un ensemble (22) propulsif à hélice pour un aéronef (20) comportant une nacelle (24), une hélice (26) monté à rotation autour d'un axe (Z) de rotation dans la nacelle (24), et un dispositif (34) de blocage de la rotation de l'hélice (26) comportant : - au moins un élément (36) de verrouillage stationnaire ; - au moins un bras (44) de verrouillage rotatif monté pivotant entre une position de verrouillage et une position de libération dans laquelle le bras (44) ; caractérisé en ce que l'élément (36) de verrouillage stationnaire comporte un cran (38) formé dans le bord (40) périphérique circulaire d'un plateau (42) fixe coaxial à l'axe (Z) de rotation, le bras (44) de verrouillage comportant un tronçon (48) extrémité libre équipée d'un ergot (50) destiné à être reçu dans le cran (38) lorsqu'il occupe sa position de verrouillage et que l'hélice (26) occupe sa position angulaire indexée. Figure pour l'abrégé : Figure 3The invention relates to a propeller propulsion assembly (22) for an aircraft (20) comprising a nacelle (24), a propeller (26) rotatably mounted around an axis (Z) of rotation in the nacelle (24), and a device (34) for locking the rotation of the propeller (26) comprising: - at least one stationary locking element (36); - at least one rotatable locking arm (44) pivotally mounted between a locking position and a release position in which the arm (44); characterized in that the stationary locking element (36) comprises a notch (38) formed in the circular peripheral edge (40) of a fixed plate (42) coaxial with the axis (Z) of rotation, the arm ( 44) locking comprising a section (48) free end equipped with a lug (50) intended to be received in the notch (38) when it occupies its locking position and the propeller (26) occupies its angular position indexed.
