MOBILE TURBOMACHINE BLADE

摘要

A mobile turbomachine blade comprising a vane defined by a stack of elementary sections that are planar in a radial direction, each elementary section being positioned radially at a height H, height H being expressed as a percentage of the total height of the vane, and being located by the sweep angle λ of same and the dihedral angle v of same, in which the change in sweep angle λ depending on height H is such that sweep angle λ reaches a maximum for a height &EEgr;λ&Mgr;, value &EEgr;λ&Mgr; being between 5% and 40%, and sweep angle λ is increasing between 0% and &EEgr;λ&Mgr;, and in which the change in dihedral angle v depending on height H is such that dihedral angle v is a decreasing function of height H, for heights H between 0% and a value Hvl, value Hvl being between 10% and 40%.
