Steady and unsteady aeroelastic simulations of the HIRENASD wind tunnel experiment

Neumann, Jens and Ritter, Markus (2009) Steady and unsteady aeroelastic simulations of the HIRENASD wind tunnel experiment. IFASD 2009 - International Forum on Aeroelasticity and Structural Dynamics, 21-25 June 2009, Seattle, WA (USA).

This paper presents recent results of steady fluid-structure-interaction simulations as well as results of unsteady elastic motion simulations of the HIRENASD (High Reynolds Number Aero-Structural Dynamics) wind tunnel model that were carried out at the Institute of Aeroelasticity in Göttingen. The main objectives of these investigations were the validation of our in-house computational aeroelasticity software for the simulation of fluid structure interaction on the one hand and the computational fluid dynamics solver TAU (development of the DLR) on the other hand against experimental results obtained from the HIRENASD project. With respect to this validation, particular attention was paid to check whether the static deformations of the wing as well as the pressure distribution on the surface of the wing could be predicted correctly. Furthermore, the results of the unsteady simulations were analyzed and validated additionally with respect to the position, the movement and the intensity of the shock evolved on the wing oscillating at high frequencies.
