  • Means for controlling a pitch change system comprising an anti-rotation device, a pitch change system equipped with said control means, and a corresponding turbine engine
    Patent number: 10648406
    Abstract: A controller for controlling a system for changing the pitch of blades of a turbine engine propeller, the controller includes a fixed member (28) and a member (29) which is movable in translation along a longitudinal axis (X) relative to the fixed member (28), and an anti-rotation device (33) configured so as to prevent the rotation of the movable member (29) relative to the fixed member (28) about the axis (X). The anti-rotation device includes a longitudinal structural crossmember (35) which is mounted by a first and a second end (36, 37) on the fixed member, and support and guide unit (57) integrally in translation the movable member along the axis (X), the crossmember extending radially outside the movable member and the fixed member relative to a radial axis (Y) which is perpendicular to the axis (X) and being guided through the support and guide unit.

  • Pitch change system equipped with means for supplying fluid to a control means and corresponding turbine engine
    Patent number: 10549843
    Abstract: A system is configured to change the pitch of blades of at least one turbine engine propeller provided with multiple blades. The system includes a control means acting on a connecting mechanism connected to the blades of the propeller. The control means includes a stationary body and a movable body translatable along a longitudinal axis (X) relative to the stationary body and defining two chambers. A fluid supply means is configured to be connected to a fluid supply source and to supply the chambers. The fluid supply means includes at least one channel. The channel is arranged and extends along an axis (Q) parallel to the longitudinal axis in an overthickness of a wall of the stationary body, the overthickness extending radially inside relative to the longitudinal axis.

  • MEANS FOR CONTROLLING A PITCH CHANGE SYSTEM COMPRISING AN ANTI-ROTATION DEVICE, A PITCH CHANGE SYSTEM EQUIPPED WITH SAID CONTROL MEANS, AND A CORRESPONDING TURBINE ENGINE
    Publication number: 20180058324
    Abstract: The invention relates to a means (27) for controlling a system for changing the pitch of blades of a turbine engine propeller, the control means (27) comprising a fixed member (28) and a member (29) which is movable in translation along a longitudinal axis (X) relative to the fixed member (28), and an anti-rotation device (33) configured so as to prevent the rotation of the movable member (29) relative to the fixed member (28) about the axis (X). According to the invention, the anti-rotation device comprises a longitudinal structural crossmember (35) which is mounted by means of a first and a second end (36, 37) on the fixed member, and support and guide means (57) integrally in translation the movable member along the axis (X), the crossmember extending radially outside the movable member and the fixed member relative to a radial axis (Y) which is perpendicular to the axis (X) and being guided through the support and guide means.
