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.
