Abstract
Gas turbine engines having moveable inlet guide vanes and stator vanes are described herein. An example gas turbine engine includes a casing defining a flow passageway to a compressor. The casing includes an outer radial wall and an inner radial wall. The compressor includes alternating stages of rotor blades and stator vanes in the flow passageway. The gas turbine engine also includes an inlet guide vane in the flow passageway upstream of a first stage of rotor blades of the compressor. The inlet guide vane extends between the outer radial wall and the inner radial wall. The inlet guide vane includes an outer radial panel coupled to the outer radial wall, an inner radial panel coupled to the inner radial wall, and a middle panel between the outer radial panel and the inner radial panel. The middle panel is rotatable relative to the outer and inner radial panels.
