This book provides the latest achievements of numerical methods and experimental means developed and demonstrated by the DLR researchers for the CleanSky 2 LPA Cross Capability Demonstrator (XDC). These developments have been made in order to establish design processes and tools for the prediction, assessment, and measurement of the integration of future propulsion systems for large passenger aircrafts. The XDC thus provided high-fidelity CFD and CAA tools as well as further developed prediction tools for noise and aero-elastics and advanced testing means. For each of the methods a short introduction is given and their applicability is described using examples from the project helping to find the right method supporting future design and integration work.

Fritz Boden is Researcher at DLR Göttingen where he works for the development of optical measurement techniques for in-flight application and optical measurements in rotating systems, furthermore he is involved in the development of flight test instrumentation for aeroacoustic measurements. He was coordinator of the AIM and AIM² projects, managed the XDC demonstrator within CS2 LPA and is managing the DLR work within the Clean Aviation projects OFELIA and COMPANION. During AIM and AIM² he served as volume editor and chapter author of the book “Advanced In-Flight Measurement Techniques” (Springer, 2013, ISBN 978-3-642-34737-5). In parallel to the organization of a dedicated workshop for researchers and industrial flight test engineers, he published the book “AIM² - Advanced Flight Testing Workshop” (BoD Books on Demand, 2013, ISBN 978-3-7322-3740-1).
