Abstract
The invention relates to a turbine engine air flow guide assembly including: a structural arm (); and a guide vane () on the lower surface of the structural arm, comprising a leading edge (), a trailing edge (), and a camber line (), said vane and arm extending radially about an axis (X-X) of the turbine engine and defining therebetween an air flow channel. The structural arm () comprises: an upstream end () having a guide vane profile () and comprising a leading edge () aligned with that of the vane; and a shoulder () located on the lower surface of the arm, defining a neck in the channel. The assembly is characterized in that the area (A) of the section of the channel at the neck is between 0.7 and 0.9 times the area (A) of the section of the channel at the leading edges.
