Bakker, Tristan (author)
To reduce greenhouse gas emissions in aviation, innovative propulsion systems such as battery-powered electric aviation are essential. These systems are carbon neutral when powered by 100% green electricity. However, widespread adoption requires overcoming challenges including improving energy density, lowering costs, and maintaining safe...

Quad-planes combine hovering and vertical takeoff and landing capability with fast and efficient forward flight. Regular Quad-planes with dedicated pusher motor can be subject to gust disturbances, and are not well-equipped to deal with actuator faults. Dual-axis Tilt-Rotor quad-planes are more maneuverable due to their overactuation. This also...

Enroute Air Traffic Controllers (ATCOs) determine the appropriate course of action by scanning radar displays to identify and select a flight that requires clearances to ensure safe and efficient operations within their airspace sector. After selecting a flight of interest, ATCOs visually compare the flight parameter displayed in the flight...

In response to the growing demand for air travel, major airports are approaching critical thresholds in their infrastructure capacity. As the transportation sector continues to expand, it is increasingly important to address environmental concerns that arise from aspects, such as noise annoyance and fuel consumption. This paper aims to enhance...

This study presents a new approach for integrated tail assignment and maintenance task scheduling decision support. Wasted maintenance resources, restricted fleet availability for schedule flexibility, inconsistent planning, and no emphasis on schedule resilience are all inefficiencies that now arise from airlines' separate and manual tail...

Short-haul flights, known for their high carbon intensity relative to distance, are increasingly challenged by high-speed rail (HSR), a viable and environmentally friendly alternative. This study develops a model adapting the “Transit Network Design and Frequency Setting Problem” to high-speed rail, focusing on optimizing existing networks...

Nijhof, Daan (author)
Following the European Green Deal, transport- related emissions must be reduced by 90% in 2050. While aviation contributes to a significant share of these emissions, the substitution of flights for rail travel is often considered to achieve a reduction in emissions of greenhouse gasses. Mostly, travelers consider this option when the full trip...

Efficient maintenance scheduling is a critical objective for aircraft carriers and Maintenance Repair and Overhaul Organizations (MROs) to minimize aircraft downtime. While predictive maintenance models have improved, accurately identifying materials, especially spare parts, for specific maintenance events remains challenging. This paper...

Burgers, Tim (author)
In recent years, Artificial Neural Networks (ANN) have become a standard in robotic control. However, a significant drawback of large-scale ANNs is their increased power consumption. This becomes a critical concern when designing autonomous aerial vehicles, given the stringent constraints on power and weight. Especially in the case of blimps,...

Climate change poses a significant global challenge and the aviation industry, a major contributor to greenhouse gas emissions, must address its environmental impact. As the demand for air travel continues to rise, transitioning to sustainable forms of aviation becomes crucial. This paper focuses on the challenges and opportunities associated...

Hierarchy is a network property that identifies the organisation and importance of network elements. Public transport systems consist of stops organised by connections, which can be regarded as networks. In a Public Transport Network (PTN) with a high hierarchy, the number of elements gradually decreases as their importance increases, where the...

Since the commercialisation of air travel, demand for air transport is increasing. Optimal system capacity utilisation at airports has therefore become crucial. As available resources such as land, buildings and human are scarce and airline tickets need to be financially affordable, airports optimise their system while maximising capacity within...

Bruno, Francesco (author)
Demand for long-distance transport has been steadily increasing over the last years, worsening the environmental impact of the transport sector. Despite European governmental bodies and policy-makers directed considerable efforts towards the substitution of short-haul flights with greener rail alternatives, the desired results do not appear to...

In order to enable the safe and efficient integration of Unmanned Aerial Vehicles into very low level airspace, modern day research focuses on the development of new traffic services and procedures. One of these is the geovectoring protocol, which aims to reduce traffic complexity by setting limits on the allowed ground speed, course, and...

Several investigations have been undertaken to study the velocity and temperature fields associated with the thermal mixing of fluids, and resulting thermal striping in a T-junction. The T-junction thermal mixing and fatigue phenomenon is a major area of study for the purposes of safety, maintenance and operational life in the nuclear industry,...

Since the first cargo flight in 1910 (Morrell [42]), air cargo has proven to be of great value to society. With over US $6 trillion worth of goods being transported through air cargo, accounting for around 35% of all global trade measured by value (Boeing [15]), it is impossible to deny its significance in today’s world. Air cargo provides us...

Ride-pooling is a key concept for the future of human mobility and vital in the roll-out of Mobility-as-a-Service (MaaS). Pooling allows individuals to travel at a reduced fare (when comparing to a private alternative) due to the reduction in operating costs as the usage of the vehicles is increased; essentially, the main intentions of pooling...

In order to reduce aircraft emissions during on-ground operations, electric taxiing systems (ETS) have been intensively researched to take over or assist in part of the taxiing phase of a flight. One of these ETS is the TaxiBot, deployed by Smart Airport Systems (SAS). While a number of papers have been researching this vehicle routing problem ...

Excessive nitrogen deposition from anthropogenic emissions has a global impact on natural biodiversity. While aviation emissions have been studied in the context of climate change and air quality, this is not true for nitrogen deposition. Meanwhile the growth of the aviation industry is likely to increase the relative contribution of aviation...

Due to the growing demand in air transport, measures need to be taken to reduce the impact of noise and emissions on local communities and the environment. The generic nature of current departure procedures leaves room for improvement in the form of aircraft type dependent departure trajectories. In this study a trajectory optimization model is...
