A turbine engine rotor blade including an airfoil defined by plane airfoil sections stacked in a radial direction, each airfoil section being positioned radially at a height H, where height H is expressed as a percentage of the total height of the airfoil, and being identified by its sweep angle λ and its dihedral angle &ngr;, wherein the sweep angle λ varies as a function of height H in such a manner that the sweep angle λ reaches a maximum at a height HλM, the value HλM lying in the range 5% to 40%, and the sweep angle λ increases from 0% to HλM, and wherein the dihedral angle &ngr; varies as a function of H, the dihedral angle &ngr; being a decreasing function of height H for heights H lying in the range 0% to H&ngr;1, H&ngr;1 lying in the range 10% to 40%. |
