Modeling for physics based aircraft predesign in a collaborative environment

Kurzfassung

The work presents a collaborative design environment, developed to account high fidelity analysis in the aircraft pre-design stage for conventional and unconventional configurations. The approach build up on centralized model architecture, based on the DLR developed namespace CPACS, and on available CPACS compatible aircraft design competences, distributed among DLR and KTH, communicating each other via a distributed architecture. In the presented approach, the centralized model is generated by the CPACScreator, a management system under development at KTH, capable to instantiate in a time efficient manner CPACS models, which are suitable for high fidelity analysis. A design process is setup between DLR and KTH, to support the designer towards an all-physics based design, already at the early stages of the development. The multiple disciplinary solvers available are accessible via a decentralized architecture, and integrated in a collaborative workflow by means of the open source framework RCE. The approach is tested for the pre-design analysis of conventional and unconventional configurations. Results for both cases are presented.
