Common numerical methods & common experimental means for the demonstrators of the large passenger aircraft platforms

The integration of advanced propulsion systems into the aircraft, and the assessment of their benefits related to e.g. fuel burn, noise emission and potential further measures, is one of the major activities of the Large Passenger Aircraft (LPA) Platform 1 of the Clean Sky 2 initiative. In order to optimize and assess the potential of advanced propulsion integration, it is necessary to establish suitable design, evaluation, and measurement tools. The so-called Cross-Demonstrator-Capabilities (XDC-) activities have been set up to develop and demonstrate powerful numerical and experimental methods for aerodynamic, aeroacoustics and aeroelastic simulation and measurement tasks, supporting the dedicated demonstrators of LPA. The paper will give an overview of the XDC activities and some examples of the developments related to this demonstrator.
