Overview of the Versatile Options to Define Fuselage Structures within the CPACS Data Format

Kurzfassung

This paper summarizes the main functionalities of the CPACS fuselage structure description that includes the definition of arbitrary sheets and structural profiles which can be combined with a variety of material definitions to so-called structural elements. Besides the definition of these structural elements, the definitions of structural members, such as stringers, frames, floor structures and pressure bulkheads as well as the definitions of the complex load introduction regions that transfer loads from the wings and the empennage into the fuselage shell are introduced. Moreover, exemplary models generated with different mesh generation tools developed at DLR Institute of Structures and Design are presented. These models are suitable for subsequent static or dynamic structural analysis. Finally, a new approach for the automated generation of the detailed structural fuselage description based on global design rules and restrictions within an extra support tool is discussed.
