Abstract

An apparatus is provided for an aircraft propulsion system (20). This apparatus includes an inner housing structure (72) extending axially along and circumferentially about an axis (22). A radial outer side of the inner housing structure (72) forms an inner peripheral boundary (84) of a flowpath (70). The inner housing structure (72) includes an inner case (86), an inner platform (88) of a guide vane structure (80), a flowpath wall (90) and a bulkhead (92). The flowpath wall (90) is axially adjacent the inner platform (88) along the inner peripheral boundary (84) of the flowpath (70). The flowpath wall (90) is spaced radially outboard from the inner case (86). The flowpath wall (90) is configured with a flowpath wall acoustic treatment (136C) extending along the inner peripheral boundary (84) of the flowpath (70). The bulkhead (92) extends radially between and is connected to the inner case (86) and the flowpath wall (90).
