Mihailescu, Georgiana (author)
Given the enduring issues of human-induced climate change, the appeal of strategies aimed at reducing greenhouse gases has never been greater. CO2 is the most concerning greenhouse gas due to the large quantity already emitted into the atmosphere and the ongoing excessive emissions from anthropogenic activities. The transportation sector...

With renewed interest in the development of civil supersonic aircraft, their return in the future is becoming more ever more likely. The environmental impact of emissions in the stratosphere on climate and the ozone layer therefore needs to be explored. The stratospheric ozone levels determine the amount of harmful ultraviolet radiation reaching...

Stremming, Luca (author)
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...

Arblaster, Thomas (author)
Through exploratory scenario development, this study delves into the environmental impacts of European commercial aviation. Climate targets and the adoption of alternative aviation fuels (AAF) following ReFuelEU Aviation are assessed, considering e-fuel produced from direct air capture (DAC) and hydrogen aircraft. A novel method is applied,...

Global passenger air traffic has doubled in the 13 years prior to 2019, and is expected to double again over the next 20 years or so. Growing demand for aviation is met by a corresponding increase in jet fuel being burned by aircraft, releasing multiple pollutants into the atmosphere. Besides disturbing the Earth’s radiative balance, these...

Hybrid-electric aircraft represent a promising solution for the urgent need to decarbonize short-haul flights and bolster aviation sustainability. Nevertheless, the realization of hybrid-electric aircraft demands rigorous environmental impact analysis, given the substantial investments, time, and research required for technology development....

van Buren, Floris (author)
Currently, the entire aviation sector accounts for 2.5% of global emissions. To commit to the Paris Agreement by 2050, new emerging technology is necessary. Electric aircraft emerged as one of the promising solutions to decarbonize the aviation sector. However, the introduction of electric aviation (EA) causes a shift from kerosene to...

The aviation industry is shouting out its aim to reach ”net-zero carbon” by 2050. Nevertheless, air traffic is expected to grow up until then, and if fuel consumption is reduced by new technologies and aircraft, other sources of global<br/>warming such as N Ox emissions and contrails are less considered. Therefore, the climate impact improvement...

Emerging in the domain of composite manufacturing, thermoplastic polymers can enable the reduction of process times, costs, and waste. In this study, lifecycle assessment (LCA) is used to evaluate a design for a carbon fibre-reinforced thermoplastic (CFRTP) wing rib, made from carbon fibre and polyetherketoneketone (CF/PEKK). The CF/PEKK rib is...

Hu, Willy (author)
Flying characteristics of a multi-engined light general aviation (GA) aircraft during and after an engine failure is often a major safety consideration when both designing and operating the aircraft. In the meantime, the propellers, being large rotating masses, can exert considerable gyroscopic effect on the aircraft during flight, itself...

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...

Ravishankara, Amogh (author)
The aviation industry is one of the most challenging sectors to decarbonise. There is an urgent need to reduce emissions in order to meet its committed goal of achieving net-zero flying by 2050. Along with the existing and proposed decarbonization options such as electric aircraft, hydrogen fuel, and operational<br/>improvements, a hard-to-abate...

Żarnowska, Agata (author)
The current impact of the aviation industry on climate change poses little choice for aviation companies but to invest in sustainability. One way to do this is to develop and implement sustainable innovations in aircraft. However, the question is how it can be validated whether an innovation is sustainable. To do so, this research uses...

Previous studies have estimated that over 16,000 annual early deaths are induced by global aviation emissions. Combined with a growing industry, this calls for sustainable developments to reduce the negative impact on human health. However, the potential application of more sustainable technologies varies amongst aircraft size and range. Thus,...
