Abstract: A turbine engine impeller including a disc bearing vanes, the roots of which are fitted in grooves which are substantially parallel to an axis of revolution of the disc. The root of each vane is connected to a blade by an integrated platform, the platforms of said vanes cooperating so as to form a radially inner wall of a duct for a flow passing through the blades. The impeller further includes two independent annular plates which are fixed to the disc, a first of said plates being mounted upstream of the disc and comprising a transverse annular portion which is supported on an upstream face of the roots of the vanes, and a second of said plates being mounted downstream of the disc and comprising a transverse annular portion which is supported on a downstream face of the roots of the vanes.
