Aviation is an important contributor to anthropogenic climate change. As indirect greenhouse gases, nitrogen oxides (NOx = NO + NO2) add to the Effective Radiative Forcing (ERF) induced by aircraft emissions. This work addresses a better understanding of emission mitigation by investigating dependencies between engine parameters and emitted...

This thesis focuses on simulating the refuelling process for a liquid hydrogen-powered commercial aircraft. The liquid hydrogen is intended to flow from the refuelling truck, through a transfer line, into the aircraft’s tank using pressure feed. The numerical simulation was built upon an existing tank model, however it did not consider the...

Hydrogen fuel cells are set to play an important role in decarbonizing the aviation sector. They operate at higher efficiencies than turbine engines, but their low operating temperature requires a dedicated thermal management system. The added drag, weight and parasitic power of such a system has a high impact on aircraft performance and its...

Following the Paris Accords, the aviation industry aims to become climate neutral by 2050. In this line, electric vehicles that tow aircraft during taxiing are a promising emerging technology to reduce emissions at airports. This paper proposes an end-to-end optimization framework for electric towing vehicles (ETVs) dispatchment at large...

The aviation sector contributes to environmental problems like climate change, resource depletion, and air pollution. We perform a systematic literature review of life cycle assessment studies to map the environmental impacts in the sector and provide methodological recommendations. The sector is divided into cross-cutting systems, namely...

To be the first carbon-neutral continent by 2050, the European Union (EU) should decarbonize the aviation sector. According to the ReFuel initiative, sustainable aviation fuels (SAFs) are crucial in reducing carbon emissions from the sector. The Clean Sky 2 program by the EU commission, shortlisted four promising technologies - hydro...

Within this thesis report the transition to LH2 infrastructure at the airport is tackled. Specifically, how the airport can develop and adopt the infrastructure needed for LH2 supply logistics, storage, and refueling is researched. This process can be defined as a socio-technical transition in which a new niche technology (LH2 aviation...

The airline industry is growing and so are its emissions. To diminish the airline industry's increasing emissions, carbon-neutral growth for this industry is adopted. Sustainable aviation fuels (SAF) are considered an important aspect to comply with these goals and a large upscale of the SAF industry is needed. Therefore, the European Commission...

One of the major emitters of CO2 is the aviation industry which keeps growing. A solution to reduce carbon emissions is to focus on Sustainable Aviation Fuels (SAF) such as biofuels or synthetic fuels or to focus on sustainable alternative technologies such as electric-powered or hydrogen-powered aircraft. A literature review is conducted that...

Trajectory optimization has been an active area of research for air transport studies for several decades. But almost all flight optimizers proposed in the literature remain close-sourced, which presents a major disadvantage for the advancement of scientific research. This optimization depends on aircraft performance models, emission models, and...
