What is it about?
The work describes a preliminary methodology assessment for the automatic optimisation of a nacelle intake using either a standard decoupled approach and a fully coupled model to represent the engine. A Design of Experiment is used to study the influence of geometric parameters for a standard flight model nacelle and the sensitivity to the engine model is discussed.

Why is it important?
The work provides a first insight into a procedure for nacelle intake optimisation where the presence of the engine fan is actively modelled through a fully coupled method, based on the body force representation. In view of the reduction of the intake length/diameter ratio, the development of modelling approaches that consider the effect of the fan on the intake flow is mandatory, as a decoupled approach fails in reproducing the real flow field.
