As traditional fossil fuels become scarcer and more attention is given to environmental impact of the combustion of fossil fuels, for next-generation aircraft, the focus of development will mainly be on reducing fuel consumption. Open rotor engines have the advantage over conventional turbofans that they are expected to perform 25% to 30% better...

All ships rely on many on board systems to reliably complete their missions (e.g. transporting containers, laying pipes or protecting the seas). However, for many of these ships, the detailed design of these systems is put off until the later stages of the design. For most ships, this will create no problems. However, for those complex vessels...

As the transformation of the electricity generation progresses, the number of power electronic-based devices connected to the electricity grid is expected to grow. To ensure the stability of the power system in a scenario with high penetration of power electronic converters, the dynamics and stability characteristics of these devices have to be...

Airfoil optimizations require costly high-fidelity solvers. By replacing the expensive solver with a cheap to evaluate surrogate model genetic optimization becomes feasible and a global optimum can be obtained. This thesis investigates applicability of surrogate model based optimization for airfoil optimization and provides recommendations...

Airborne wind energy is a new research field that aims to harvest winds at high altitudes. The pumping kite concept investigated at the Delft University of Technology is based on leading edge inflatable kites that divide a generation cycle into three phases: traction, retraction, and transition. This research project aims to optimise the...

Research in using Topology optimisation as a tool to improve the design process of bridge design. The research focuses on implementing Topology optimisation in the design process of architects and engineers. As an example topology optimisation is used to propose a design for a pedestrian bridge in Amsterdam.

Variable Stiffness Laminates are created by spatially varying the fiber orientation resulting in designs that makes use of curved fibers rather than Uni-directional fibers to tailor the properties to design requirement. The advent of automated manufacturing methods such as Automated Fiber Placement and Tailored Fiber Placement has made variable...

This thesis concerns the cap set problem in affine geometry. The problem is illustrated by the card game SET and its geometrical interpretation in ternary affine space. The maximal cardinality of a cap is known for the dimension one to six. For the four lowest dimensions, a maximal cap is constructed and the optimality of its size proven. From...

This research aims at modeling the trajectory followed by the Galileo spacecraft during a variety of flybys about the Galilean moons. The chosen flybys have good Earth’s elevation angles and either low or high closest-approach altitudes, so that the comparison of the two can give relevant insight into the accuracy of the corresponding...

Striving to improve structural efficiency the aerospace industry shows increasing interest in variable-stiffness composite laminates. Advanced fiber placement is a hybrid manufacturing technique that offers the flexibility of both filament winding and automated tape laying. With the development of this novel system curved tows can be placed and...

The Trailing Suction Hopper Dredgers (TSHD) are typically used for the transportation of soil. The soil in the hopper can be removed by hydraulic transport using water jets and the discharge at the bottom level of the hopper. The soil fluidization and transportation is jet assisted. The unloading process can take quite some time; the unloading...

Atmospheric free flight scaled flight testing is an affordable way to investigate the dynamic properties of an aircraft, while enabling a wider range of test possibilities than a windtunnel. This research is the first step into the development of a scaled flight testing model and as such will highlighted the difficulties and discrepancies which...

Currently the production process of acoustic guitar factories does not result in instruments with equal dynamical behaviour, due to the varying material properties of wood from tree to tree. Experienced individual guitar builders are able to handle those material variations, but this is a labour intensive process because there is no structured...

In this research computational fluid dynamics (CFD) is used to model a vertical axis wind turbine. Well known turbulence models | i.e. the k-epsilon and k-omega SST model | are used and compared in their performance against each other and a set of experimental data. The formal research question is "What models are available for the simulation of...

In this thesis work we solve the problem of optimal placement and sizing of distributed generation by using an original Fuzzy Adaptive Particle Swarm Optimization algorithm and a Mixed Integer Linear Programming formulation of the problem. The goal of integrating Fuzzy Logic in Particle Swarm Optimization is to be able to overcome some of the...

As of yet, there are virtually no practical tools available for incorporating both developer and consumer preferences within a floorplan design. This study aims to deliver a proof of concept for such preference-based design systems, and their application within the commercial property development process. A research model is presented that is...

Current autonomous steering controllers are designed based on either optimal control strategies or on average human driver steering behavior. Individual drivers may wish to steer differently than those controllers do. Such conflicts can be mitigated by customizing individual steering behavior. This thesis aims to develop a method to...

Due to fierce competition on the electricity market, many wind energy related research projects are currently aimed at cost reduction. In order to establish cost reduction, more and more wind turbines are being clustered in (offshore) wind farms. Major drawback of wind farms however, is the energy production loss due to aerodynamic wake...

Multi model adaptive control is an emerging field that has proven to be successful in mitigating limitations of classical adaptive control by providing more quicker and faster adaptation. In this method instead of one single parameter varying controller, multiple fixed parameter controllers pertaining to different operation regimes are utilized....
