Abstract (en)
The arm has a ventilation case (24) comprising a centering finger (40) engaged in an orifice (44) of a body. The orifice is formed in a bottom wall (48) of a reinforcement (49) of a base (32) of the arm. A thermal protection shield (28) is fixed on the body and closes an open side of the body. The finger of the case supports an annular part (46) e.g. washer, which is fixed on an end of the finger, by welding or brazing. Shape of the part is such that the part performs an anti-rotation function for the finger and the case in the body around a longitudinal axis.
