Early design decisions have a significant influence in the final success of the project. One of the most important decisions is to determine the system architecture, as it highly impacts the performance of the system. System architecture optimization can be used to determine the best possible architectures through the formulation of an...

The present study, which was carried out in collaboration with GKN Fokker, focuses on incorporating bird strike crashworthiness requirements within a multidisciplinary optimization (MDO) framework. During the preceding three-month internship in the same company, a pivotal contribution to this project was the development of an Abaqus interface...

This work introduces the Surrogate Advisory System (SAS), a Python package that aims to reduce the existing complexity when working with surrogate-based MDAO systems. SAS automates most of the steps for a CPACS-based MDAO workflow and drastically reduces required efforts to integrate surrogate models within MDAO systems. Key developments...

One of the challenges in executing an MDO system is the selection of the best performing MDO architecture in terms of computational effort for a given MDO problem. To address this, several comparative studies have been created, which analyze the relative performance of MDO architectures with respect to internal features of MDO problems, such as...

In the past decade, MDO researchers have developed capabilities to simultaneously optimise the shape and internal structure of aircraft based on coupled high fidelity Computational Fluid Dynamics and Finite Element Analysis. However, to date the finite element methods used for the structural analysis are typically linear and are known to be...

For decades the space domain has been used for military purposes. When enemy forces establish counter-space capabilities, this could become a weakness. Responsive Space is a concept that focuses on replenishing lost capabilities and/or granting additional capabilities from space assets quickly. The continuous miniaturization of technologies has...

Reusable rocket stages is a trend in launch vehicles that have been observed for some time now. Even reusable upper stages have been seen in the Space Shuttle, Kistler K-1 and now the SpaceX Starship. This thesis is on the development of a genetic optimisation algorithm to determine the economic feasibility of upper stage reusability. Genetic...

The second-generation of supersonic civil transport has to match ambitious targets in terms of noise reduction and efficiency to become economically and environmentally viable. High-fidelity numerical optimization offers a powerful approach to address the complex trade-offs intrinsic to this novel configuration. Past and current research however...

The Delft University of Technology is developing an MDO tool for the conceptual design of transport aircraft. However, the current program is not able to investigate the influence of the undercarriage design on the weight, drag and geometry of transport aircraft. This research proposes a new design method for the undercarriage, for which a new...

In the aerospace industry, demanding time constraints make it practically impossible to fully explore the design space of aircraft movable surfaces. The hinges, located at the interface of the movable surface, require a time-consuming analysis. This thesis presents a methodology enabling the near instantaneous selection of an optimal hinge. An...

Multidisciplinary Design Analysis and Optimization (MDAO) promises major advances in aircraft design. However, judging from todays aircraft, MDAO is clearly not fully embraced by the industry yet. This is due to technical difficulties (coupling incompatible tools) and non-technical barriers (intellectual property).<br/><br/>Recent research, such...

Beijer, Bastiaan (author)
Multidisciplinary Design Optimization (MDO) frameworks, capable of performing overall aircraft design studies become too complex to be comprehended by a single team of experts. Therefore, there is an increasing need to develop distributed analysis frameworks in which both tools and experts are integrated in a single network. This poses great...

Blended wing body aircraft represent a paradigm shift in jet transport aircraft design. Stepping away from the conventional tube-and-wing philosophy, they promise benefits over existing or future conventional aircraft. The most significant challenge with the concept is the increased coupling between aircraft design disciplines that has...

The use of advancements in computing technology has enabled designers to perform more thorough and more detailed design studies. Multidisciplinary Design Optimization (MDO) architectures provide users with guidelines on how to structure their MDO problem, including the linking of disciplines and how to perform the optimization. However, complex...

Current wing design processes are strongly governed by cruise design requirements. This approach to wing design leaves little room for high-lift device design optimization where trade-offs may be required between cruise wing and high-lift wing design. Moreover, the optimization of high-lift devices typically focuses on optimizing flap/slat...

Aircraft concepts with high aspect ratio wings have been investigated more extensively in the recent past, as such configurations would reduce the induced drag significantly. At the same time, the high aspect ratio challenges the wing’s aero-structural stability (flutter). Therefore there is a need to perform aero-structural analysis already...

At present, on the aviation market a need exists for lighter and more efficient aircraft than the ones dominating the airspace today. Beside the reduction in operating costs and air pollutants of these new generation aircraft, this reduction in fuel use can result in several advantages with respect to the performance of the aircraft like...

An opportunity was identified to improve the traditional landing gear design process. Especially in the conceptual design phase, lots of man-hours are consumed by making the same calculations over and over again, for different concepts. Often, an existing gear is therefore used as initial starting point, to simplify the design process. This...
