Variable guide vane for aircraft propulsion system

An assembly for an aircraft propulsion system, comprising:

• a propulsor rotor configured to rotate about a rotational axis, wherein the propulsor rotor is an open propulsor rotor;
• and
• a guide vane structure axially next to and downstream of the propulsor rotor, the guide vane structure including a stationary structure and a plurality of guide vanes arranged circumferentially about the rotational axis, and the plurality of guide vanes comprising a first guide vane, wherein the guide vane structure is an open guide vane structure;
• the first guide vane comprising a camber line, a leading edge, a trailing edge, a leading edge section and a trailing edge section, the first guide vane extending longitudinally along the camber line from the leading edge to the trailing edge, the leading edge section forming the leading edge and pivotally coupled to stationary structure, and the trailing edge section forming the trailing edge and movably coupled to the leading edge section, wherein the trailing edge section is coupled to the stationary structure through the leading edge section.
