Automatically Generated Aeroelastic Analysis Models including Physics Based Control Surface Representation

摘要

Defence budget cuts and increasing competition lead to new challenges for the military aviation industry. Due to this, new aircraft have to be developed in fewer design loops and with reduced engineering costs. Thus, it is important to have access to reliable engineering data already during the conceptual design phase. To provide to reliable data from the concept phase for further detailed design, a high modelling effort usually is necessary. Automated analysis model generation enables the usage of multi fidelity simulation in early design phases due to lowering the analysis model generation expenses. The core of this approach for an integrated multi-fidelity multidisciplinary design analysis and optimization platform is a parametric geometry definition. This geometry is generated by the in-house program Descartes. From the geometry different analysis models can be generated with additional information from a central database. The focal point of this publication is the fully automated generation of simulation models for aeroelastic analysis and multidisciplinary design optimization. These capabilities were recently enhanced with physics based control surface modelling by using a detailed parametric geometry definition. Through this information concerning the flight performance of a new design or the aeroelastic effectiveness of a control surfaces is available.
