Supersonic flow diffuser with energy redistribution

摘要

A supersonic diffuser having a plurality of blades therein for dividing the diffuser channel into a plurality of approximately axisymmetric ducts wherein a portion of said ducts ingest a boundary layer along at least one of the walls of the supersonic diffuser. The blades in the diffuser channel have their upstream ends bent away from the wall having the boundary layer to redirect the flow into the ducts. In one embodiment the wall between the duct having the boundary layer and the duct adjacent to the duct having the boundary layer is made in two sections with both sections being bent away from the wall having the boundary layer, to provide internal redistribution between the two ducts.
