Abstract
A propulsion system having an axial direction relating to a principal direction of propulsion, and a height direction perpendicular to the axial direction. The propulsion system includes a duct configured to convey a flow of fluid along the axial direction, and a heat exchanger disposed within the duct. The heat exchanger is defined between an inlet face and an outlet face and is configured to convey the flow of fluid from the inlet face to the outlet face. A heat exchanger length is defined as a minimum distance between the inlet face and the outlet face and wherein the heat exchanger length varies along the height direction such that a resistance to the flow of fluid through the heat exchanger varies along the height direction.
