摘要

1. An assembly of fixed blades for a gas turbine engine with a longitudinal axis (X), containing a casing (18) and at least two angular sectors (8.1) equipped with blades (12), fixed in the casing (18), each of which comprises a shelf (20), from which at least one blade (12) extends radially outward, and a fastening rib (22) protruding from the shelf (22) radially inward for fastening the corner sector (8.1) in the casing (18), the stationary blade assembly contains a ring (26) made of a wear material resting on a support (28) fixed in the casing (18) from the side of the rotor blade assembly by means of a plurality of threaded connections (30) passing through the support (28) of the ring (26) made of wear material, the stationary vane assembly also contains pins (36, 36 ', 36' ') for radial fixation of the corner sectors (8.1) inserted into the first holes formed in the fastening ribs (22) and the fastening clip (34) located opposite wear rings relative to casing (18) and forming, together with the casing (18), a groove in which the fastening ribs (22) are located, while the axes of the said holes run parallel to the longitudinal axis (X), the fastening clip (34) is fixedly fixed in the casing (18 ) using the same threaded connections (30) with which the wear ring support is fixed in the casing (18). ! 2. An assembly according to claim 1, characterized in that each pin (36) comprises a skirt (44) projecting radially outwardly orthogonal to the axis of the pin (36), said skirt (44) axially delimits the head (36.1) and the shank (36.2) , while the head (36.1) is inserted into the first hole (42) of the fastening clip (34), and the skirt (44) is supported by the bearing surface of one of its
