Abstract

L'invention concerne un ensemble (22) propulsif à hélice comportant : - une nacelle (24) ; - une hélice (26) montée à rotation autour d'un axe (Z) de rotation dans la nacelle (24) ; - un dispositif (34) commandé de blocage de la rotation de l'hélice (26) ; caractérisé en ce que le dispositif (34) commandé de blocage comporte : - un premier élément (36) de verrouillage rotatif qui est solidaire en rotation avec l'hélice (26) ; - un élément (38) de verrouillage stationnaire qui est monté coulissant sur la nacelle (24) parallèlement à l'axe (Z) de rotation de l'hélice (26) entre une position de libération et une position de verrouillage. Figure pour l'abrégé : Figure 2A propeller propulsion assembly (22) comprising: - a pod (24); - a propeller (26) rotatably mounted around an axis (Z) of rotation in the nacelle (24); - A controlled device (34) for blocking the rotation of the propeller (26); characterized in that the controlled blocking device (34) comprises: - a first rotary locking element (36) which is integral in rotation with the propeller (26); - a stationary locking element (38) which is slidably mounted on the nacelle (24) parallel to the axis (Z) of rotation of the propeller (26) between a release position and a locking position. Figure for abstract: Figure 2
