Data integration in preliminary Airplane Design

A multidisciplinary approach to preliminary airplane design is seen as one of the major improvements for future design tasks. Several approaches can be found in the literature. The key to a multidisciplinary approach is a central model that contains all data and is accessible for all domains. The goal of this work is to analyze three different models in respect to their benefits for data integration in preliminary airplane design. The models are Cpacs, developed at the Dlr, Step, published by the Iso, and the Uml, released by the Omg. For this purpose a lexical overview of the important terms is given. Additionally several methods for the classification of information are introduced and requirements for information models are set up. The main part of the work is contributed to the analysis of the different models. A conclusion is drawn that suggests a solution for a future information model using a combination of the Uml / SysML and Xml. Subsequently a prototype for a converter tool, that processes Cpacs data to Step is developed. The converted geometry data of the Attas Vfw 614 is used for validation and shows the quality of the tool.
