摘要
An inlet diffuser for a jet engine and methods for mixing boundary layers of air in compact inlet diffusers with high offset and high aspect ratio apertures are disclosed. The inlet diffuser includes an inlet diffuser body that includes elongate structures that are configured to allow a first portion of boundary layer air located between the elongate structures to flow within a channel, restrict the first portion of boundary layer air from flowing across either elongate structure, and allow a second portion of boundary layer air located outboard of the elongate structures to flow across the elongate structures and into a region of internal volume inward of the channel, wherein the second portion of boundary layer air is pushed away from the internal surface of the diffuser body by the elongate structures as the second portion of boundary layer air flows across the elongate structures in an inboard direction.
