Zusammenfassung:	A fan inlet diffuser housing includes a housing body of composite material and includes a heat exchanger interface portion positioned between an ejector housing portion and a bypass housing portion. A first transition region is formed between the heat exchanger interface portion and the ejector housing portion including an air cycle machine end reinforcement patch proximate to a heat exchanger interface. The air cycle machine end reinforcement patch includes a first patch thickness and a second patch thickness, and a ratio of the first patch thickness to the second patch thickness is between 2.02 and 3.11. An ejector is formed having an ejector gap width between a nozzle portion and a diffuser portion within the ejector housing portion of the housing body. The diffuser portion has a downstream ejector gap width, and a ratio of the downstream ejector gap width to the ejector gap width is between 4.62 and 5.01.
