Estimating the term…
A moving blade for a wheel of an aircraft turbine engine, including an aerodynamic aerofoil and an outer heel defining the aerofoil. The heel includes a platform and a first lip that projects from the platform. The first lip is inclined upstream and peripherally along an axis of elongation. The heel includes a row of ribs that are arranged at a distance from each other. The row of ribs extends along the axis of elongation and from the platform up to the first lip. The ribs are arranged upstream of the first lip in such a way as to generate turbulence upstream of first lip.
A movable vane for a wheel of an aircraft turbomachine, said vane comprising an aerodynamic blade extending along a stacking axis and an outer heel delimiting said blade along said stacking axis, said heel comprising a platform and a first lip protruding from said platform, the first lip being inclined upstream at an acute angle to said stacking axis, said first lip extending circumferentially along an axis of elongation, wherein the heel comprises a row of ribs spaced from each other, said row comprising at least two ribs, said row of ribs extending along said axis of elongation, each rib extending along said stacking axis from said platform to said first lip, each rib being arranged upstream of the first lip according to the direction of gas flow around said blade so as to generate turbulence upstream of said first lip.
