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...

With Multidisciplinary Design Analysis and Optimization (MDAO) a fully automated aircraft design analysis is set up and optimization algorithms are used to obtain better designs by balancing the synergy between components. In the EU project AGILE, a new methodology and framework were developed to make the MDAO approach more accessible to...

This paper investigates whether spring-foam technology in an aircraft seatpan can reduce weight and at the same time provides equal or better comfort. Firstly, through literature studies and iterative design process a prototype seatpan was designed and developed using spring-foam technology. This was then tested against standard aircraft seat...

The Flying-V is a novel flying wing concept where the main lifting surface has been fully integrated with the passenger cabin. Previous studies have focused on the aerodynamic and structural design of the airframe; but, prior to determining which engine-airframe integration alternative is most beneficial (e.g. boundary layer ingestion, distributed...

The need to reduce the pollutant impact of aircraft emission drives the research on aircraft design progress through off-design performance improvement. This report proposes to investigate the effect of maneuver load alleviation technology via wing control surfaces. A methodology is presented to model the MLA technology in aircraft conceptual...

In this thesis, a methodology is presented to predict impact damage on next-generation (composite) aircraft based on maintenance data of in-service (metal) aircraft. To achieve this conversion, an analytical model is developed to Model Impact Damage on Aircraft Structures (MIDAS) for composite (-C ) and metal (-M ) aircraft. The model...

Loss of control-in flight (LOC-I) is one of the causes of catastrophic aircraft accidents.
Fault-tolerant flight control (FTFC) systems can prevent LOC-I and recover aircraft from
its precursors. One group of promising methods for developing Fault-Tolerant Control (FTC) system is the Adaptive Critic Designs (ACD). Recently one ACD...

The aviation sector and its associated activities contribute to climate change, damage to the environment, community noise, and local air pollution. As a consequence it affects the health and quality of life of citizens that live close to airports, and through climate change every person on earth. To reduce the impact of air travel and thereby...

Due to the complexity of aircraft spare part management, the aviation supply chain and ecosystem are not deemed as transparent as desired. As a result, participants face additional cost of communication and compliancy as proprietary component data is not made immediately accessible. To solve these problems, Maintenance, Repair and Overhaul (MRO)...

Spaan, Tessa (author)
Aircraft maintenance is inherently unpredictable due to differences in failure rates between components. This results in high variance inflow in repair shops, which in case of insufficient capacity yields long turnaround times and thus the need for additional components in stock. The aim of this research project is to determine the effect of...

To overcome the disadvantages of radar vectors and to improve efficiency and safety of terminal airspace operations, EUROCONTROL has proposed the so-called Point Merge System (PMS) technique for merging inbound traffic flows. As the PMS provides better predictability, it can potentially offer significant fuel and environmental benefits as well...

As the aviation sector keeps expanding, a growing interest in technologies that can reduce the dependency from non-renewable energy sources, both for economic and environmental reasons, has led researchers to investigate the opportunities offered by the electrification of flight. It is theorized that the use of electrically powered machines as...

To allow the incorporation of engine design in the Aircraft Initiator conceptual design tool, a modular engine design and performance estimation tool has been created, which is intended to allow the study of the effects of changes to engine architecture on the complete aircraft design. It generates estimates for engine thrust, specific fuel...

In the year 2050, global anthropogenic radiative forcing from aircraft emissions are projected to increase significantly. Recent studies have considered climate optimized flight trajectories to be a promising measure to mitigate non-CO2 emissions’ environmental impact, which is highly sensitive to locus and time of emissions. Estimating the...

Tilt-rotor aircraft combine the helicopter’s benefit of VTOL capability and the flight performance that turboprops possess on range, speed and endurance. Tilt-rotor aircraft have the potential to decrease airport congestion and average flight delay in passenger transportation, while benefits are numerous in i.e. search and rescue, disaster...

This is a thesis report in Integrated Product Design, along with STG Aerospace in Cwmbran, Wales. It is a design project centered around the entry lighting of an aircraft galley. The analysis provided possibilities to reduce stress using light. These are showing information from trusted and authoritative sources, enlarging...

Airports are trying to increase their airside efficiency by implementing the concept of Airport Collaborative Decision Making (A-CDM). At the heart of A-CDM lies the Target Off-Block Time (TOBT). The TOBT is the time at which the aircraft is estimated to be ready, with all doors closed and boarding bridges removed. The
TOBT is used by other...
