Parametric Structural Modelling for Aeroelastic and Aeroacoustic Analyses of an Aircraft Rear Fuselage

Kurzfassung

For the development of numerical methods for aeroelastic analysis and vibration analyses on future aircraft configurations, representative reference models for the aerodynamics and the aircraft structure are necessary. Only very few models with a sufficient level of detail are publicly available. The DLR tool MONA is used for the for the generation of parametric aircraft models, i. e. finite element models and linear aerodynamic models, to realistically represent the global structural and aeroelastic dynamics of an aircraft. In the project, the focus was on the extension of the modelling capabilities of MONA to the generation of fuselage models of sufficient detail for aeroelastic and vibroacoustic analysis. Those models were then passed on to project partners for the respective analyses. The presentation was given at the "XDC Common Numerical Methods and Experimental Means - Final Workshop" @DLRK2023.
