Abstract :
Boundary Layer Ingestion (BLI) effects are the new and special issues caused by the in-depth integration of airframe and propulsion system. Based on a mathematical model of the distributed propulsion system and a sliced CFD model of SAX-40, this paper presents a detailed numerical research on the BLI effects of distributed propulsion configuration. The influence regularities of BLI on aerodynamic parameters are summarized and analyzed. Computation results indicate that BLI has extraordinary potential to raise the Cl and L/D ratio, thus resulting in a better flight performance.
