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.

Variable-pitch stator vane for an aircraft turbine engine

A set of compression stage(s) of a turbomachine, forming an annular fluid passage and comprising at least one annular stator platform and/or at least one annular rotor platform having an outer longitudinal profile inclined (I/I) inwards and upstream with respect to a nominal profile of the fluid stream, where the inclination (I/I) of the outer longitudinal profile of the or each of the annular platforms, relative to the nominal profile of the fluid stream, oscillates along the circumference of the annular platform or platforms, between a maximum value in front of the blades of the annular platform and a minimum value between each pair of adjacent blades of the annular platform.

Wavy tilting of platforms at the rotor-stator gaps in a turbine engine compressor

A turbine engine rotor blade including a plurality of blade cross sections stacked along an axis Z between a blade root and a blade tip defining therebetween the height of the blade, each blade cross section including a leading edge () and a trailing edge () and a chord defined by the length of the segment which extends from the leading edge to the trailing edge and ensuring that:
