Abstract

L'invention concerne un ensemble propulsif (22) à hélice pour un aéronef (20) comportant une nacelle (24), une hélice (26), et un dispositif (34) de blocage de la rotation de l'hélice (26) comportant un bras (46) de verrouillage qui est monté pivotant entre une position de verrouillage dans laquelle il coopère avec au moins un cran (42) de l'autre élément (36) de verrouillage pour bloquer la rotation de l'hélice (26) et une position de libération dans laquelle le bras (46) est écarté dudit autre élément (36) de verrouillage ; caractérisé en ce que le bras (46) de verrouillage est rappelé élastiquement dans sa position de libération, tandis qu'il est poussé vers sa position de verrouillage au moyen d'un actionneur (58). Figure pour l'abrégé : Figure 3The invention relates to a propulsion assembly (22) with a propeller for an aircraft (20) comprising a nacelle (24), a propeller (26), and a device (34) for blocking the rotation of the propeller (26) comprising a locking arm (46) which is pivotally mounted between a locking position in which it cooperates with at least one notch (42) of the other locking element (36) to block the rotation of the propeller (26) and a release position in which the arm (46) is moved away from said other locking element (36); characterized in that the locking arm (46) is elastically returned to its release position, while it is urged towards its locking position by means of an actuator (58).
