The invention relates to a system for controlling propeller blade pitch in a turboshaft engine, comprising a first track connected to a propeller blade and rotatable to set the incidence of said blade; a second track; a member (60) for actuating the first track, arranged between the first and second tracks and having a recessed angular portion; and at least one locking member (64) between the first and second tracks in the recessed angular portion and in the notch. The member (64) can assume a normal over-center position in which the first and second tracks rotate together, and a release position in which the assembly of the first track, the member (64) and the member (60) can rotate.
La présente invention se rapporte à un système de commande de calage de pale d'une hélice d'un turbomoteur, comprenant : - une première piste raccordée à une pale d'hélice, dont la rotation assure le calage en incidence de cette pale; - une seconde piste; un élément d' actionnement (60) de la première piste, agencé entre les première et seconde pistes, et présentant une portion angulaire évidée; et - au moins un élément de blocage (64) prévu entre les première et seconde pistes, logé dans la portion angulaire évidée et dans l'encoche. L'élément (64) peut occuper une position normale d' arc-boutement rendant les première et seconde pistes solidaires en rotation, et une position de déblocage autorisant le déplacement en rotation de l'ensemble comportant la première piste, l'élément (64) et l'élément (60).
