Boundary Layer Ingestion (BLI): The process of utilising the near-wall, lower momentum flow over an airframe as an input to the propulsion system to improve overall efficiency.

Highly integrated propulsion promises benefits, but poses challenges for engine and aircraft designers. Boundary-Layer Ingestion Key To MIT/NASA D8 Hopes | Aviation Week Network ...

Specification: The positive effect of boundary layer induction and the associated fuel savings can be exploited primarily in cruise flight.With regard to the system weight of the propulsion system, ...

NASA says the first-ever large-scale wind-tunnel tests of a robust fan capable of operating in turbulent flow have proved successful, marking an early step on the path to a new generation of ...

Scientists at the University of Bristol in collaboration with the University of Salford have uncovered the root cause behind the particularly irritating noise produced by boundary layer ingesting ...

In the development of future aircraft concepts, propulsion systems with boundary layer ingestion (BLI) have a valuable potential for multiple reasons. For example, improved integration of the engines ...
