    Abstract: A compressor system is provided with an impeller disposed to rotate in a compressor chamber. A diffuser extends around the impeller to collect fluid leaving the impeller. Main flow is discharged from the diffuser through an exit providing an opening that extends circumferentially around the compressor. A bleed annulus extends around the compressor and has a consistent cross-sectional area. A bleed port that opens the diffuser to the bleed annulus and that is configured to divert a bleed flow of the fluid from the main flow before discharge through the exit. The bleed port has a circumference around the compressor and a flow size that varies around the circumference. Variation in the flow size of the bleed port maintains a uniform flow distribution around the exit.

    Abstract: A precooler system having a symmetrical precooler core that is optimized to be integrally mounted to the turbofan engine, regardless of the turbofan engine size, is provided. The provided precooler system optimizes available space between a turbofan engine and the nacelle, and does not substantially increase weight and cost. The provided precooler system may be flexibly implemented as either a right handed precooler system or a left handed precooler system.
