Design of a Rear BLI Non-Axisymmetric Propulsor for a Transonic Flight Experiment

Nowadays, the increasing demand for reducing the environmental impact of civil aviation is leading to more sustainable aircraft technologies. In the context of aircraft propulsion, Boundary Layer Ingestion (BLI) is considered one of the most promising solutions, although the high level of integration between the airframe and propulsors becomes a major challenge in the design process. The present work deals with a CFD based shape optimization of a BLI-360 propulsor, starting from a simplified two-dimensional axisymmetric model as a basis for the three-dimensional design.
