Patent attributes
A propulsion system is provided including a first vane extended along the radial direction. The first vane is configured to rotate relative to a vane axis extended along the radial direction. A second vane is extended along the radial direction. The second vane is positioned aft along the axial direction of the first vane. The second vane forms an inlet opening proximate to a second vane leading edge, and the second vane forms an outlet opening proximate to a second vane trailing edge. The inlet opening and the outlet opening together allow a flow of fluid through the second vane. A heat exchanger is positioned within the second vane. The inlet opening and the outlet opening allow the flow of fluid in fluid communication with the heat exchanger.
