MOVING BLADE FOR A WHEEL OF A TURBINE ENGINE

The invention relates to a moving blade (1) for a wheel of an aircraft turbine engine, the blade (1) comprising an aerodynamic aerofoil (2) and an outer heel (7) defining said aerofoil (2). The heel (7) comprises a platform (8) and a first lip (9) that projects from said platform (8). The first lip (9) is inclined upstream and peripherally along an axis of elongation. The heel (7) comprises a row of ribs (10a-10c) that are arranged at a distance from each other. The row of ribs (10a-10c) extends along the axis of elongation and from said platform (8) up to said first lip (9). The ribs (10a-10c) are arranged upstream of the first lip (9) in such a way as to generate turbulence upstream of said first lip (9). 本发明涉及一种用于飞行器涡轮机的轮的移动叶片(1)，叶片(1)包括空气动力学翼型件(2)和限定所述翼型件(2)的外后跟(7)。后跟(7)包括平台(8)和从所述平台(8)突出的第一唇缘(9)。第一唇缘(9)沿着伸长轴线向上游和外周倾斜。后跟(7)包括一排彼此间隔开一距离布置的肋(10a-10c)。一排肋(10a-10c)沿着伸长轴线延伸并从所述平台(8)延伸到所述第一唇缘(9)。肋(10a-10c)布置在第一唇缘(9)的上游，以在所述第一唇缘(9)的上游产生湍流。
