Abstract
An apparatus is provided for an aircraft propulsion system. This apparatus includes a variable guide vane. The variable area vane includes an airfoil, and the variable guide vane is configured to pivot about an axis. The airfoil extends spanwise along the axis to a tip. The airfoil extends longitudinally along a camber line between a leading edge and a trailing edge. The airfoil extends laterally between a first side and a second side. The airfoil includes a vane acoustic structure. This vane acoustic structure includes a first skin and a plurality of chambers within the airfoil. The first skin at least partially forms the first side. A first of the chambers is fluidly coupled with one or more perforations in the first skin.
