Open propulsion systems are promising concepts for civil aircraft due to their high propulsive efficiency. This paper considers an open fan engine with adjustable rotor and stator blades and assesses the performance and mass of such a configuration for a short-medium range aircraft in the early phase of conceptual design. CFD-generated maps are used to model the propulsor on overall engine level.
