Abstract: Jet engines with boundary layer ingestion (BLI) could offer significant reductions in aircraft fuel burn compared with podded turbofans. However, the engine fans must run continuously with severe inlet distortion, which ...

Abstract: In this paper, steady and unsteady computational fluid dynamics (CFD) have been used to investigate stall inception for a modern low-pressure-ratio transonic fan. The computational results are validated against measurement ...

Abstract: A combined experimental and computational test program, with two low-pressure ratio aero-engine fans, has been used to identify the flow mechanisms at stall inception and the subsequent stall cell growth. The two fans have ...
