An integrated bicycle computer mount for aerodynamic handlebars: Development of a lightweight and aerodynamic solution for integration of bike computers into aerodynamic handlebars of professional road cycling bicycles

The goal of this graduation thesis is to design a bicycle computer mount (BCM) that connects bike computers with road cycling handlebars in a visually appealing, and aerodynamic way. Initiated between Delft University of Technology and a leading sports equipment company, the project addresses the evolving needs of cyclists regarding maximum...

Optimization of a Multi-Element Airfoil for a Rigid Airborne Wind Energy Kite

Airborne wind energy (AWE) systems benefit from a high lift airfoil to increase the power output, to that end, multi-element airfoils are investigated for AWE applications. This thesis aims to optimize a multi-element airfoil for a rigid AWE kite that operates in a pumping cycle. Since the kite has distinct operational phases, i.e., reel-out and...

Knowledge Based Engineering framework for preliminary spaceplane design

The concept of a spaceplane, a launch system that is a combination of an airplane and a rocket, is one of the most promising concepts of sustainable access to space. Along its trajectory, it experiences most extreme conditions with frequently opposing design requirements, making it one of the most complicated challenges in aerospace engineering....

A Discrete Adjoint Method for Two-Phase Condensing Flows Applied to the Shape Optimization of Turbine Cascades

This paper presents a fully turbulent two-phase discrete adjoint method for metastable condensing flows targeted to turbomachinery applications. The method is based on a duality preserving algorithm and implemented in the open-source CFD tool SU2. The optimization framework is applied to the shape optimization of two canonical steam turbine...

Improved design of a high lift system for general aviation aircraft

Optimization of a single slotted flap with dropped hinge is performed with the objective of increasing the payload of a propeller driven 4-seater general aviation aircraft. Within the optimization loop, two-dimensional aerodynamic characteristics are evaluated using the MSES code, while three-dimensional aerodynamic characteristics and weight...
