Abstract: A header duct and method of forming a header duct includes an inlet portion having a planar inlet, an outlet portion have a plurality of planar outlets, and a transition portion extending continuously from the inlet portion to the outlet portion. The transition portion has a bend and internal topography defining a non-monotonic cross-sectional area distribution between the inlet and outlet portions. The transition portion can further include a bulbous region extending in a lateral direction of the duct and a protrusion located along an inside radius of the bend.

Abstract: A system and method of using the system includes an open-loop path and a closed-loop path. The open-loop path is configured to extract bleed air from a compressor section of a gas turbine engine through a bleed air port and discharge bleed air to an ambient environment. The closed-loop path is configured to circulate a working fluid through a heat exchanger, a turbine, and a condenser with a pump. The heat exchanger is fluidly coupled to the bleed air port and configured to extract heat from the bleed air to boil the working fluid for driving the turbine and a component rotationally coupled to the turbine.

Abstract: An environmental control system includes a primary heat exchanger operable to transfer heat from an air source to a refrigerant in a generator flow and output an air flow. An ejector is operable to produce an intermediate refrigerant flow based on receiving the generator flow as a motive fluid and drawing a vapor refrigerant flow as a suction fluid. A refrigerant condenser is operable to convert the intermediate refrigerant flow to a liquid refrigerant flow. A pump is operable to provide the refrigerant to the primary heat exchanger from a portion of the liquid refrigerant flow. An expansion device is operable to expand the liquid refrigerant flow prior to entering an evaporator. The evaporator is operable to convert the liquid refrigerant flow to the vapor refrigerant flow and produce a cooled evaporator air flow output based on the air flow.

Abstract: A laminate composite structure having at least one tubular region and at least one bonded region. The structure has a first composite layer, a second composite layer, a cavity, and one or more reinforcing fibers. Each composite layer comprises composite material with a top face and a bottom face opposite the top face. The top face of one is joined to the bottom face of the other along an interlaminar region. The cavity separates the bottom face and the top face to form a tube. The tube has an internal boundary defined by the bottom face and the top face. The reinforcing fibers line the internal boundary and are arranged so that the reinforcing fibers reduce the propensity of the composites layer to separate under internal pressure loading.
