Abstract

The present application relates to an axial turbomachine low-pressure compressor stator. The stator includes an outer annular casing made of organic matrix composite materials. The stator also has groups of vanes having an outer shroud, several rows of stator vanes spaced axially from one another, and segments of inner shrouds at the inner ends of the vanes. The rows of stator vanes are aligned along the circumference of the casing. Each outer shroud is pressed against the inside of the casing so it can be fastened by means of attachment pins. The outer shroud, and the rows of vanes of said group forming a one-piece assembly. The device of the present application reduces the number of vane attachment elements to a few attachment portions distributed on the shroud.
