Abstract:
A diffuser pipe (38) of a compressor diffuser assembly (28) for gas turbine engines defines a depressed local area (58) in the pipe wall of an upstream section of the diffuser pipe (38). The depressed local area (58) is bent into the diffuser pipe (38) to reduce the accumulation of fluid boundary layer and improve stall margin of the diffuser pipe (38).
