Guide vanes assembly with position-maintaining device

A turbine engine nozzle extending about an axis and comprising:

• a vane assembly mounted between an outer shroud and an inner shroud, and
• a position retaining device configured to be placed in an elastically prestressed state between the inner shroud and an inner platform of the vane assembly to apply a stress onto the vane assembly oriented towards the outer shroud,
• wherein contact between the inner shroud and the inner platform is obtained by one same surface of the position retaining device, and
• wherein prestressing is performed for a compression corresponding to a displacement of between 0.2 mm and 1 mm between a state of rest and the elastically prestressed state.

• a vane assembly mounted between an outer shroud and an inner shroud, and
• a position retaining device configured to be placed in an elastically prestressed state between the inner shroud and an inner platform of the vane assembly to apply a stress onto the vane assembly oriented towards the outer shroud,
• wherein contact between the inner shroud and the inner platform is obtained by one same surface of the position retaining device,
• wherein the vane assembly comprises at least one hollow vane to allow the passing of a radial strut securing the inner shroud to the outer shroud, and
• wherein the nozzle further comprises at least two position retaining devices circumferentially connected and each arranged against at least one vane.

• wherein the position retaining device comprises at least one curved metal sheet presenting a C-shape,
• wherein a first end of the at least one curved metal sheet corresponds to a first contact zone between the position retaining device and the inner platform of the vane assembly when the position retaining device is mounted in the nozzle, and
• wherein a second end of the at least one curved metal sheet corresponds to a second contact zone between the position retaining device and the inner shroud when the position retaining device is mounted in the nozzle.
