AIR RECOVERY ASSEMBLY WITH IMPROVED AERODYNAMIC PERFORMANCE

摘要

The invention proposes an air flow rectification assembly, comprising: at least one stator blade (21), - a structural arm (30), the blade and the arm extending radially about an axis ( XX), the arm having: - an upstream end portion (31), having a stator blade profile, and comprising a leading edge (310) aligned with that of the blade, a downstream portion (33) ), and an intermediate portion (34) comprising an extrados wall (44) extending between an upstream end point (A) and a downstream end point (B), characterized in that the upstream end point is distant from the d attacking the arm by an axial distance (xA) between 0.2c and 0.5c, c being the length of the axial cord of the blade, and the angle (αA) of the tangent to the wall extrados extreme point upstream is equal to that at the extreme point down to a degree.
