“…The frameworks similar to Paper [IV] and as shown in Figure 6.3 are CESIOM [22] by Royal Institute of Technology, design and engineering engine (DEE) by TU Delft [18] and DLR framework [23]. CESIOM also shows that the geometry created can be propagated to low and medium fidelity of CFD.…”

With the ever growing complexity of aircrafts, new tools and eventually methods to use these tools are needed in aircraft conceptual design. To reduce the development cost, an enhancement in the conceptual design is needed.This thesis presents a knowledge-based aircraft geometry design tool RAPID and the methodology applied in realizing the design. The parameters used to create a geometry need to be exchange between different tools. This is achieved by using a centralized database or onedata concept. One-database will enable creating a less number of cross connections between different tools to exchange data with one another. Different types of aircraft configurations can be obtained with less effort. As RAPID is developed based on relational design, any changes made to the geometric model will update automatically. The geometry model is carefully defined to carry over to the preliminary design.The validation of RAPID is done by implementing it in different aircraft design courses at Linköping University. In the aircraft project course, RAPID was effectively used and new features were added to the obtained desired design. Knowledge-base is used to realize the design performance for the geometry with an integrated database approach for a multidisciplinary aircraft conceptual design.

In 2005, the German Aerospace Center (DLR) started an internal project, called TIVA, with the main goal to strengthen the multidisciplinary collaboration in the field of conceptual aircraft design. This approach was intended not only to couple disciplinary analysis tools from different institutes, but also to establish a process which keeps the disciplinary experts in the loop as well. Linking the tools and corresponding experts, this process should finally enable each discipline to study the consequences of their new concepts and technologies on overall aircraft level. One major component of this process is a new data exchange file format called CPACS, which serves as central interface and common language between the disciplinary analysis tools. The second key component is the integration framework, which allows the user to couple the single tools to multidisciplinary process chains for analysis and optimization tasks. Since the end of the TIVA project in 2009, the system is continuously being enhanced and extended in TIVA's successor-project VAMP, as well as in several other research projects which are based on this technology. For the near future, it is further planned to open the system with its major components to external partners and to use it for common projects with Industry and Universities.

“…The first module is the conceptual aircraft design tool, VAMPzero [22], which is used as aircraft initializer to provide the initial overall synthesis of the aircraft performance, such as the fuel consumption and operating empty mass (OEM). Based on a multi-fidelity architecture, the program allows making use of the aircraft performance values evaluated by external tools.…”

An automated CFD-based analysis process for applications at the early aircraft development stages is presented. The robustness of the implemented process, which relies on a knowledge-based layer implemented into the automated pre-processing step of the geometrical components, allows taking advantage of high fidelity simulations, also for large explorations of the design space. The well-known aircraft configuration DLR-F6 is chosen to verify the automated analysis process. The CFD analysis process is integrated into the DLR multi-fidelity aircraft design environment, which relies on the DLR open source distributed framework RCE, and the DLR central data model CPACS. The overall aircraft design synthesis is performed for a conventional passenger transportation aircraft configuration, by making use of variable fidelity methods for the aerodynamic analysis. The results discuss the impact of employing CFD-based analysis into overall aircraft design applications.
