Abstract [en]

An aircraft is a multifaceted product which requires cooperation between different engineering domains. Therefore, design of an aircraft is essentially a multidisciplinary activity with necessity of integrating dierent design tools to get an optimized product. At Linkoping University, a design framework is being developed to assist in the evaluation and optimization of various aircraft vehicle system architectures with the help of integrating a geometric, aerodynamic and dynamic models early in the conceptual design phase. This framework helps to identify a preliminary system concept for an energy optimized aircraft architecture with the focus on more electrical aircraft. As a case study the performance and geometrical aspects of an EMA (Electromechanical actuator) are evaluated and optimized.

Abstract [en]

In a product development process, it is crucial to understand and evaluate multiple and synergic aspects of systems such as performance, cost, reliability and safety. In order to improve the foundations for decision-making, this thesis presents methods that are intended to increase the engineering knowledge in the early design phases.

In complex products, different systems from a multitude of engineering disciplines have to work tightly together. Collaborative design is defined as a process where a product is designed through the collective and joint efforts of domain experts. Thus, a Collaborative Multidisciplinary Design Optimization (CMDO) process is proposed in the conceptual design phase in order to increase the likelihood of more accurate decisions being taken early on.

To enable higher fidelity based CMDO, it is necessary to validate the tools and models utilized. This can be done with so-called low cost demonstrators. The physical demonstrators increase the engineer’s confidence regarding the final product by validating the models as well as revealing many unknowns and thus further increasing the engineering knowledge.

The performance of the presented methods is demonstrated with two industrial applications, aircraft conceptual system design and industrial robot design.

Abstract [en]

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.
