Assessment of the Influence of Boundary Layer Ingestion (BLI) on the Axial Fan
Journal of Physics: Conference Series, 2021 Abstract Boundary Layer Ingestion (BLI) is a technology which is effective to reduce fuel consumption of future commercial aircrafts. However, the inlet distortion caused by BLI has a negative on the engine performance. This paper investigates the effect of the inlet total pressure distortion on the aerodynamic performance of the fan ...

Numerical Simulation of Boundary Layer Ingesting (BLI) Inlet/Fan Interaction [PDF]
50th AIAA/ASME/SAE/ASEE Joint Propulsion Conference, 2014 Future civil transport designs may incorporate engine inlets integrated into the body of the aircraft to take advantage of efficiency increases due to weight and drag reduction. Additional increases in engine efficiency are predicted if the inlet ingests the lower momentum boundary layer flow.
