The environmental impact of aviation is a well-known issue scientists all around the world are desperate to tackle. The population that can afford air travel is growing and this demand is likely to double within the next 20 years. This increasing demand comes at a hefty price: the emissions of greenhouse gases cause climate change and local air...

The world is faced with two concurrent trends. The first is the growing demand for air travel in the long term. The second is the need to cut aircraft emissions due to environmental goals and ambitions set by authorities. Fully-electric aircraft are currently infeasible due to the limited battery specific energy and power. Hybrid-electric...

Due to strong demand for air travel before the COVID-19 pandemic, major airports were constrained in capacity and this issue was expected to worsen in the coming decades. Novel aircraft (concepts) could help to alleviate these capacity constraints. However, the market competitiveness and impact of novel aircraft is often challenging to assess,...

In this thesis project, it is investigated to what extent the energy consumption of an electric aircraft can be improved by using a variable pitch and RPM propeller, including energy recuperation during the descent, with respect to a constant pitch propeller. The largest percentage of total mission energy saved using the variable pitch propeller...

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...

Unconventional aircraft designs have the potential to lower the impact of aviation on emissions and climate as compared to conventional aircraft designs. However, the flight dynamics behaviour of such unconventional configurations must be carefully evaluated by studying Stability and Control (S&C) characteristics to design safe aircraft and...

Air transport is facing an important challenge when it comes to the reduction of its environmental footprint. Hybrid electric aircraft offer a potential solution to reduce in-flight emissions. The essence of hybrid electric aircraft is to combine multiple energy sources and energy conversion systems, in order to improve the overall energy...

Exposure to excessive community noise has become a large environmental health concern. Noise pollution continues to increase while it is accompanied by direct, as well as cumulative adverse health effects. In addition, prolonged exposure to excessive noise levels also has a negative economic impact. The incorporation of numerical tools in the...

This research focuses on aircraft noise exposed urban spaces around Amsterdam Schiphol airport. In particular, a case site in Rijsenhout is studied, where a representation of the noise wave propagation due to refraction is performed. Subsequently, a series of landscape configurations regarding geometry are gradually tested through acoustic...

Increasing competition amongst airlines necessitates them to improve the efficiency of their operations. Even though maintenance, repair, and overhaul (MRO) represent a significant portion of an airline’s operational costs, aircraft maintenance scheduling is often still a manual process, producing suboptimal solutions. Airlines typically operate...

The competition in the airline industry has rapidly increased during the last decades, especially with the entrance in the market of low-cost carriers. The high costs incurred in Maintenance, Repair and Overhaul (MRO) activities are generating a great interest in the improvement of maintenance operations as a way to stay competitive in the...

The MRO market currently spans around 9.5% of the total operating cost of an airline. Of this, 70% is covered by heavy-maintenance. Reduction of these costs and improving efficiency could, therefore, be significant for an airline. A possible solution is the optimization of the long-term schedule of heavy-maintenance checks. Current approaches...

The long and therefore expensive training of aircraft maintenance technicians underline the need for accurate demand forecasts that allow for dynamic control of acquisition and training rate of personnel. This control enables human resource management to react swiftly to increases in workforce demand at times of technician shortages. To help...

The global aircraft fleet was predicted to grow by approximately 40% between 2017 and 2027 by Oliver Wyman (2017). This fast-growing fleet needs to be supported by equally developing Maintenance, Repair, and Overhaul (MRO) divisions of airlines. In light of the growing need for more efficient and technologically advanced aircraft maintenance,...

The Flying-V is a unique concept aircraft to fly more energy efficient. With the V-shape passenger cabin integrated in its wings, a new interior is created with four different seat concepts. This raises the question of how the onboard services could be designed for the Flying-V. As a matter of fact, food plays an influencing role on the overall...
