Abstract
The invention relates to an aircraft turbomachine subassembly comprising an annular duct () extending concentrically about a longitudinal axis and in which an air stream flows from upstream to downstream, the annular duct comprising a duct portion () defining a swan neck having an upstream inlet section and a downstream outlet section. A plurality of radial arms (B, B) extend circumferentially in the duct portion (). One or several intermediate walls (P, P) extend between two circumferentially adjacent arms (B, B) which form a pair of circumferentially adjacent arms among the plurality of circumferentially adjacent arms so as to locally separate, between the two arms of the pair of arms, the annular duct portion () into a radially inner portion (Ci) and a radially outer portion (Ce) further away from the longitudinal axis than the radially inner portion.
