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 ...
