Simulation eines vollständig elastischen Transportflugzeugs mit Hilfe der Strömungs-Struktur-Kopplung

Kurzfassung

Within the scope of the joint research project HINVA (High-Lift In-Flight Validation), funded by the German Federal Ministry of Economics and Technology within the fourth Aeronautical Research Program LuFo IV, a fluid-structure coupled simulation approach based on high-fidelity numerical fluid dynamics and structural analysis methods has been applied to DLR’s Airbus A320-200 Advanced Technology Research Aircraft (ATRA) in landing configuration. Coupled analyses were performed using an in-house simulation procedure built around DLR’s flow solver TAU and the commercial finite-element analysis code NASTRAN. In order to assess the influence of fuselage deformations in the context of high-lift aerodynamics, the existing coupling approach, which considers only the wing and high-lift system to be elastic, has been expanded to the full aircraft.
