  • Patent number: 10766603
    Abstract: A system changes the pitch of blades of a turbine engine propeller having a plurality of blades. The system includes a plurality of links, each link being connected to one of the propeller blades at a first interface, and a control means acting on the link and having a body movable in translation along a longitudinal axis. A load transfer module is arranged between the links and the control means and is connected to the links at a plurality of second interfaces. A first adjustment element is configured to adjust an axial position of the second interfaces along the axis to provide adjustment of the pitch of all of the blades simultaneously. A plurality of second adjustment elements are configured to adjust an axial distance between each first interface and the corresponding second interface to allow the pitch of each blade to be adjusted individually.

  • Patent number: 10011388
    Abstract: According to the present invention, the device comprises: a flange having an at least approximately trapezoidal tapered section; a counter-flange having a shape complementary to that of said flange (1); and clamping means for clamping said flange and said counter-flange one in the direction of the other, interposing the edges of said elements shaped at least partially in the shape of said counter-flange.

  • Publication number: 20180043989
    Abstract: A system changes the pitch of blades of at least one turbine engine propeller provided with a plurality of blades. The system includes a link mechanism connected to the propeller blades at a first interface, and a control means acting on the link mechanism and having a body movable in translation along a longitudinal axis. A load transfer module is arranged between the link mechanism and the control means. The load transfer module is connected to the link mechanism at a second interface. The system further includes means for adjusting the setting of the blades, the adjustment means having first adjustment elements configured to adjust an axial position of the second interface along the axis. The adjustment means also includes second adjustment elements configured so as to adjust an axial distance along the axis between the first interface and the second interface.

  • Patent number: 9341799
    Abstract: The fiber optic assembly can include two fiber optic breadboards hinged to one another along a coinciding hinge axis. Each one of the fiber optic breadboards can have a flat body having two faces and lateral edges, one of which running alongside the hinge axis, and can have a tessellation of tray locations each having a tray attachment. The fiber optic assembly can also include a plurality of fiber optic trays each having a body having a base attachable to at least one of said tray attachments, the body having a size and shape associated to one of a single one of said tray locations and a plurality of adjacent ones of said tray locations on one of said at least one fiber optic breadboards, and having a structure by which an optical fiber having a critical radius of curvature can be confined within at least one optical fiber path.
