In the Frame of the EU project ADEC, numerical simulations have been performed to reproduce the flow around an aircraft in take-off conditions with installed engine, rotating fan and high-lift devices, by modelling the external aerodynamics of the plane as well as the internal aerodynamics in the secondary flow of the engine, located under the wing. These calculations take into account most of the elements of a civil transport aircraft and allow to finely model the interactions between the engine and the airframe. The analysis allows for an evaluation of both internal and external flow features of a civil aircraft equipped with engines with very high bypass ratio.
