Abstract
A compressor diffuser for an aircraft propulsion system includes a plurality of diffuser pipes. Each diffuser pipe includes a pipe body. The pipe body extends between and to an inlet end and an outlet end. The pipe body includes a suction lateral wall and a pressure lateral wall. The pipe body further includes a transition body portion. The suction lateral wall and the pressure lateral wall extend between and to the inlet end and the outlet end to form a fluid passage. The fluid passage extends along a center position from a passage inlet at the inlet end to a passage outlet at the outlet end. The fluid passage has a cross-sectional area. The transition body portion is disposed at the outlet end. The transition body portion includes a diverging sub-portion and a converging sub-portion. The cross-sectional area increases in the diverging sub-portion. The cross-sectional area decreases in the converging sub-portion.
