Abstract
A variable-pitch stator blade includes an airfoil having a central portion with a first chord and a first skeleton line delimited by a leading edge and a trailing edge. An end portion has a second chord and a second skeleton line delimited by the leading edge and a downstream limit. A skeleton angle at a first length Iof the first chord is defined by a function G(), and the skeleton angle at a second length lof the second rope being chord is defined by a function G(). The absolute value of the average increase Aof G′() between the leading edge and the downstream limit is greater than the absolute value of the average increase Al of Gl′() between the leading edge and a point P, wherein the first length Icorresponds to the total length of the second chord.
