The aircraft cabin needs to find the right compromise between comfort and efficiency. Requirements by operatorschange the way the cabin and the fuselage will be designed in future aircraft.
The objective of this research field is the consideration of the cabin within the aircraft design process. For that purpose a set of methods for cabin and fuselage design has been developed that interact with the distributed aircraft design process of the DLR. A high level of attention is given to weights, both structural weight and weightof the cabin interior. As visible in the following figure, the design methods allow a detailed and parametricdesign of the cabin.
The cabin design is not limited to physical optimization. In cooperation with other research fields and DLR institutes important processes like aircraft turnaround and boarding are analyzed. System integration is considered. Usage of the file format CPACS allows efficient interaction with other DLR research teams.
Identification of remaining optimization potential is a key objective. In this field changing requirementsby operators and new technology influences the design of future cabins. This is especially true for future short and medium range configurations able to replace the A320 and B737.
