van Luijk, Nikki (author)The Flying V is a flying wing aircraft consisting of two pressurised passenger cabins placed in a V shape. Its longitudinal and lateral control is ensured via elevons and split flaps on the outboard wing, and rudders on the tip-mounted winglets. The goal of this study is to devise a design for the outboard wing of the Flying V through a...master thesis 2023

Brill, Patrick (author)To improve the safety of commercial air transport, pilots are required to train on simulators to recognize the characteristics of an impeding stall and subsequently correctly recover from it. To prevent negative training, it is important that the accuracy of the used simulation models is high. A manner to model the nonlinear, unsteady...master thesis 2023

Kooij, Robert (author)From the desire to reduce the impact of traveling on the environment and the increase in fuel prices over the past years, the propeller has regained interest as a propulsion mechanism in the aviation industry. Two main reasons can be found in their high propulsive efficiency and ability to combine with electric motors. The scaling of the motors...master thesis 2023

Jux, C. (author), Sciacchitano, A. (author), Scarano, F. (author)The aerodynamic characteristics of a modern road cycling wheel in cross wind are studied through force- and planar PIV measurements in the TU Delft Open Jet Facility. The performance of the 62 mm deep rim is evaluated for three tire profiles, and yaw angles up to 24°. All measurements are executed at 12.5 m/s (45 km/h) freestream- and wheel...journal article 2023

Knepper, Jorian (author)The aerodynamic behaviour of a pitched baseball depends on the combination of the translational velocity, the rotational velocity in combination with the rotation axis and the seam positions. For small spin parameters the effect of seam positions dominates the Magnus effect. This study focusses on a visual understanding of the seam position by...master thesis 2022

Hendriksen, Luuk (author)Aerodynamic load determination through integration of the surface pressure distribution is limited in accuracy by the discrete number of measurements taken. Therefore, typically relatively large numbers of spatially distributed measurements are required which increase setup complexity, latency, cost and weight while requiring physical access in...master thesis 2022

Porta i Ko, Agustí (author)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...master thesis 2022

Mordasov, Dmitrij (author)With the growing global utilisation of wind energy, lowering of its levelised cost of energy is pursued. This effort is hindered by wind turbine wakes and their detrimental effects on wind farm profitability. Most currently researched wake mitigation methods are based on wind farm system-level interventions, and there is a research gap on...master thesis 2022

Buendía Vela, Gabriel (author)Airborne wind energy systems convert the kinetic energy of wind into usable power. In general terms, this power is proportional to the ratio CL<sup>3</sup>/CD<sup>2</sup> of aerodynamic coefficients. From a structural perspective, the thickness-to-chord ratio of conventional AWE wings needs to be high to withstand the high aerodynamic loads. The...master thesis 2022

Kokkedee, Jop (author)With an ever increasing demand for sustainable energy, limitations of current sustainable technologies are studied widely. In wind farms, the so-called wake effect provides the biggest limitation on wind farm total power output. Using wind from the unaffected boundary layer to re-energize the wind flow in the wake provides a method of limiting...master thesis 2022

Grille Guerra, Adrian (author)Unmanned aerial vehicles have proliferated in the last few decades, with applications that include military, commercial and recreational. Their size and typical flight velocities are characterized by moderate Reynolds numbers <i>O</i>(10^4-10^5). For such conditions, boundary layers can remain laminar and therefore are highly susceptible to...master thesis 2022
