Czél, László (author)The thesis aimed to characterize the effects of manufacturing-induced defects, particularly gaps in variable stiffness laminates. The primary focus centered on designing a specimen capable of accurately characterizing gap effects. A refined, element-level specimen design featuring a controlled gauge zone was developed, based on pre-defined...master thesis 2024

Hyde, Edward (author)As the aviation industry has agreed on the goal of achieving net-zero CO2 emissions by 2050, various mitigation strategies are being deployed and developed. This paper focuses on reducing emissions at airports by towing aircraft instead of taxiing with their main engines; dispatch towing. This is done by developing a model to optimise the...master thesis 2024

Cuadrat-Grzybowski, Michal (author)Mitigation strategies which eliminate existing space debris, such as with Active Space Debris Removal (ASDR) missions, are now more important than ever regarding the ever-growing space debris population problem. One of the considered ASDR approaches uses a net as a capturing strategy. The benefits of such strategy are to allow for a large...master thesis 2023

Meseguer Berroy, Paula (author)Fuel consumption during the taxi phase of flight can be reduced by using electric wheel propulsion instead of aircraft engines. Currently, this can be either done by having external trucks towing the aircraft from the gate to the runway, or by incorporating electric motors on the aircraft wheels to power the aircraft without using the engines....master thesis 2023

ul-Haq, Ehshan (author)This master’s thesis focuses on the design and assembly of an innovative tow spreading line for investigating carbon fiber tow spreading through the utilization of spreader bars. The primary objective was to examine the friction behavior during the spreading process by employing multiple tension sensors. Additionally, novel monitoring concepts...master thesis 2023

Segeren, Megan (author)In this paper, the emissions mitigation potential of implementing operational towing at major European airports is evaluated. Using mixed-integer linear programming, a scenario simulating mixed taxiing operations is used to find the relationship between fixed vehicle costs and target emission savings at an airport and European level. Using...master thesis 2022

van Wilgen, Bert-Jan (author)This research examines the difference between two major component replacement strategies for the novel floating offshore wind turbines (FOWT), in terms of support vessel CO2eq emission and cost together with FOWT downtime. The first strategy is utilising a crane vessel to replace a component in offshore, this is called the heavy lift maintenance...master thesis 2022

Tiel, Roos (author)The diffuser stern is part of a design concept from Damen and the TU delft: the interceptor diffuser. This concept aims to improve the seakeeping behavior of fast ships in waves. With PIV measurements, a contribution to the development of the diffuser stern is made. The flow acceleration and detachment are studied, and a comparison with a CFD...master thesis 2021

Muhammad Sulthoanuddin Akbar, MUHAMMAD (author)Within the Indonesian national road network, Bina Marga, assisted by regional offices (Balai), manage nearly 18,000 bridges scattered across 34 provinces. Maintaining its reliability is vital as inland transportation remains the most effective mobility means for ± 270 million inhabitants. Therefore, as a road service provider under the Ministry...master thesis 2021

Urselmann, Huub (author)Composites are used in applications where the combination of low density and high stiffness is wanted, as can be frequently found in the aerospace industry. Within the composites family, discontinuous fiber composites (DFC) started to gain interest in the aerospace and automotive industry, due to their potential for high production rates. In...master thesis 2021

Kroese, Jurjen (author)Electric taxiing (ET) is a novel concept that focuses on replacing engine-powered aircraft taxiing by taxiing using electrically powered towing vehicles, called ET vehicles. The main purpose of ET is reducing the impact of aviation on climate change while at the same time saving fuel costs. In this paper, we propose two models that can be used...master thesis 2021

Benda, Bram (author)The highly fuel-inefficient aircraft taxi-phase causes the industry to consider alternative ground propulsion systems. External systems like the Taxibot are preferred over onboard systems as they do not require aircraft structural additions and recertifications. However, the operational implementation of external taxi-systems is expected to...master thesis 2020

Vos, Bastiaan (author)The international maritime sector accounts for about 2% of all global carbon dioxide (CO2) emissions, the main greenhouse gas that causes global warming. Nations meeting at the United Nations International Maritime Organization (IMO) in London have proposed an initial strategy for the reduction of greenhouse gas (GHG) emissions from ships,...master thesis 2019

van Lingen, Wouter (author)Demand for air traffic is growing worldwide. In order to accommodate this growth, existing infrastructure such as gates should be used more efficiently. One technique to increase gate utilization is by introducing gate pit-stops. Introducing gate pit-stops leads to additional towing movements which can potentially interfere with other traffic on...master thesis 2019

van Baaren, Edzard (author)Operational towing is a taxiing strategy to reduce the fuel consumption during the taxiing phase of a flight, which decreases the cost and environmental impact of taxiing. Currently, no operational electric towing systems are available that are fully electric, independent from the APU and are capable of towing both narrow- and wide-bodied...master thesis 2019

Boonstra, Rep (author)In the early 00 of this century, Keuning et al. (2007) looked into the hydrodynamic forces on the rudder and the influence of the hull and keel on these forces. Among others, they have assessed the lift and drag forces on the rudder. One of the outcomes of this study was an asymmetric lift curve; for negative rudder angles the rudder seems to...master thesis 2019

Geldermans, Daan (author)Dykstra Naval Architects are regularly designing large classic sailing yachts or motor-sailors, of which the draft is an important design restriction.The sailing performance is increased by adding lift-generating appendages,without increasing the draft. An example is a retractable centre board, havinga big influence on the sailing properties....master thesis 2018

van den Bos, Pepijn (author)With the decrease in sensor and actuator costs decentralized control strategies have become increasingly attractive, aiming to use multiple simpler robots for achieving a global objective. The problem of reaching the global objective generally results in a consensus problem requiring communication amongst the agents. The cooperative manipulation...master thesis 2018

Struijk, G.D. (author)With fuel oil the main driver for operational expenses, increasingly stringent regulations on emissions of ships and a growing environmental awareness throughout the industry, the concept of Wind-Assisted Ship Propulsion (WASP) presents itself as a means to reduce fuel consumption. Though a promising concept, the performance prediction of a wind...master thesis 2015
