In the highly uncertain environment of conceptual aircraft design and technology assessment and selection, making good decisions is of utmost importance. Aiming to contribute to improving decision quality, the problem was researched from both a technical as well as a socio-psychological perspective. In the technical perspective, the uncertainty...

In recent years, airlines have increasingly developed the ability to monitor the condition of aircraft components by means of sensors. In turn, aircraft maintenance aims to use this sensor data to predict component failures. However, the challenge remains to make use of these prognostics to generate appropriate maintenance schedules. In this...

This article investigates the estimation of aircraft mass and thrust settings of departing aircraft using a recursive Bayesian method called particle filtering. The method is based on a nonlinear state-space system derived from aircraft point-mass performance models. Using only aircraft surveillance data, flight states such as position,...

There is a growth in the use of composites for the new generation of wide-body aircraft such as the Boeing 787 and Airbus A350. This shift from using aluminium as the primary material is motivated by the benefits of using composites in design, manufacturing and operations. Composites offer the aircraft manufacturer the ability to create more...

In this thesis research, dutch aircraft noise model (NRM) calculations are compared to measurements to analyze the aircraft classification used in the model. To do so, a new implementation of the model has been set up to calculate with LVNL trackdata and NOMOS measurement data. First, the classification approach is analyzed as prescribed, which...

To study passenger contentment data and design for a better hygiene experience for a future aircraft: flying-v, researches and design were performed step by step. Firstly, to understand the overall situation of current flying experience, data were gathered from three co-creation sessions and a survey of 128 participants with experience of long...

The aerospace industry has made the transition from aluminium to carbon fibre composites on the newest, most advanced aircraft. One of the main disadvantages of composites is its high susceptibility to impacts, such as tool drops which occurs on a single point of impact. As such, these types of impact have been thoroughly studied. Nevertheless,...

A large number of stakeholders exist in the modern air traffic management ecosystem. Air transportation studies benefit from collaboration and the sharing of knowledge and findings between these different players. However, not all parties have equal access to information. Due to the lack of open-source tools and models, it is not always possible...

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...

In recent years a return of supersonic transportation has begun with companies looking to launch supersonic aircraft in the coming decade. However, supersonic environmental regulations are still based on Concorde. This thesis looks to predict the performance of new supersonic aircraft for ICAO through a low-fidelity program with a set of climate...

As all industries move towards sustainable fuels to reduce emissions, aircraft industry is still at its nascent stages. The adoption of clean energy sources has been slow particularly due to low energy density of commercially available batteries, and high volumetric density of hydrogen as a fuel. Electric aircrafts have been demonstrated but...

The environmental control system is an essential system on all modern aircraft and is the largest consumer of secondary power. System power consumption is potentially reduced by using electric compressors to feed the system, instead of bleed air. The aim of this research is to provide a first order estimate of the potential benefits on mission...

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...

The aircraft leasing industry is still operating like it is 1980, the transfer of boxes filled with paper, a scattered information landscape, opposing interests and almost zero digitisation result in significant lease transition cost. Blockchain might change this. Although other technologies exist, Blockchain can given its characteristics be an...

Traditionally, a geographical area can be monitored via land based communication systems or spaceborne remote systems for disaster prevention. However both methods have their respective limitations in terms of resolution, accuracy and real time observation. A new suborbital constellation concept offers an independent unit device which will be...

Airlines experience schedule disruptions on a daily basis. Poor weather conditions, unscheduled aircraft maintenance and congested air spaces are just a few of the causes that prevent airlines from operating their flight schedules as planned. In the third quarter of 2017 over 20% of all scheduled flights in Europe suffered from delays. Operation...

In this thesis, a methodology is developed that allows for both reliable and computational efficient robustness analysis of aircraft component distortion. This research applies to dis- tortion caused by reductive manufacturing processes that are used to obtain monolithic components from pre-stressed stock material. With the developed methodology...

Aircraft base maintenance consists of hundreds of tasks including preventive, corrective and modification tasks which have to be scheduled to a few check moments per year. The allocation of tasks to checks represents a complex scheduling problem due to the constraints involved. A mixed integer linear programming model was developed to optimize...
