Vaned impeller for aircraft turbomachine, comprising a dynamic damping device made using a member for reconstituting a gas circulation path

A vaned impeller for aircraft turbomachine, the impeller comprising several vanes succeeding each other along a circumferential direction of the impeller so as to form an annular row of vanes, each of the vanes comprising a blade as well as a heel integral with the blade tip and radially outwardly arranged as a protrusion from the same, the heel comprising a base as well as at least one sealing member radially outwardly protruding from the base the heel circumferentially extending on either side of the blade tip respectively into a first heel portion, and a second heel portion, each of the first and second heel portions having a radially inner surface partially delimiting a gas circulation path,

• wherein between adjacent first vane and second vane of the impeller, the latter also comprises a member for reconstituting the gas circulation path, the reconstituting member being arranged in a first recess provided on the radially inner surface of the first heel portion of the first vane, and in a second recess provided on the radially inner surface of the second heel portion of the second vane, the first and second recesses circumferentially opening toward each other, and each having a radially inner bottom surface for cooperating by friction with a radially outer friction surface of the reconstituting member, a radially inner surface of which partially delimits the path
• in that the path reconstituting member forms a plate,
• and in that the first heel portion of the first vane comprises a first radial retention tab circumferentially extending toward the second vane, the second heel portion of the second vane comprising a second radial retention tab circumferentially extending toward the first radial retention tab, and in that the path reconstitution member comprises, at its two opposing circumferential ends, hollow radial retention means respectively penetrated by the first and second radial retention tabs, and,
• preferably, the path reconstituting member integrating hooks at the opposite axial edges of the plate to form said radial retention means, or the plate corresponds to a part of a flattened tube, another part of which forms said radial retention means by radially outwardly covering the first and second radial retention tabs.
