Airport service road traffic performance

Evaluating airside roadway infrastructure through Level of Service analysis

Airside service roads are essential for the movement of ground support vehicles that enable efficient aircraft turnaround and overall airport operations. Despite their importance, no standardised method exists for evaluating their capacity and performance, limiting the ability of ...
Airport surface movement operations present a promising opportunity for enhancing airport sustainability, as up to 25% of airport emissions originate from taxiing aircraft. This study explores the use of Electric Towing Vehicles (ETVs) to tow aircraft to runways, eliminating the ...
Offshore wind turbines (OWTs) play a critical role in renewable energy, requiring efficient methods to predict fatigue loads on their support structures under harsh environmental conditions. Traditional fatigue assessment methods are effective but costly and impractical at scale. ...
Airports play a significant role in economic development while presenting considerable energy consumption with demands from various stakeholders. Their important environmental impact can be reduced through an optimised energy system design. In this study, a systematic framework f ...

Since the 1970s, helicopters have been vital in disaster response but face limitations in cost, infrastructure, and
maneuverability. This thesis presents the design and optimization of an emergency response flyer tailored for the
GoAERO competition. Multirotor config ...
Excess inventory negatively impacts financial performance due to increased holding and working capital costs, stock value depreciation and lost sales from other products. For durable finished goods inventory within e-commerce, this issue of excess stock could be amplified given t ...

Multi-body Aerodynamic Modeling for Novel Aircraft Configurations

Towards Knowledge-based Flight Mechanics Model

This work explores a paradigm in which isolated aircraft components are analyzed separately and combined together in a multi-body system representative of the whole geometry. The FLAPERON (FLight mechanics Analysis and PERformance OptimizatioN) toolbox is developed and employed t ...
Strategic airlift is an essential capability for the rapid global movement of cargo, particularly in crisis operations where timelines are short and cargo demands extreme. Despite the European Union's collective purchase of A400M aircraft, capability gaps remain due to the aircra ...

Six Degree of Freedom Flight Dynamics Model of a Tilt-Wing Aircraft with Trim and Stability Analysis

Implemented on the Canadair CL-84 Dynavert for Hover and Transition

One of the biggest trade-offs in aviation is between a vehicle’s ability to take-off and land vertically and its efficiency in cruising flight. The recent drive for electric vehicles creates space to consider new solutions to this trade-off. Tilt wing aircraft offer significant a ...
Inherent subjectivity, inefficiencies, and the substantial cost related to human-based visual inspection of high-pressure turbine (HPT) blades has driven research in alternative automated techniques. The
combination of computer vision (CV) and deep learning (DL) provides a co ...

Designing resilient supply chain networks

An operator-attacker-defender approach

We present an adaptation of the tri-level Operator-Attacker-Defender (OAD) model for designing resilient supply chains, addressing disruptions such as supplier failures, production shortfalls, and disabled transportation links. These disruptions impact the supply chain's performa ...
This study addresses the operational challenges of sustainable aircraft towing at hub airports, partic- ularly focusing on taxi delays. Using a queue-based discrete event simulation, airport taxi operations are modeled to evaluate the impact of tow-trucks on taxi delays and runwa ...
To accommodate the rising demand for airport resources and airspace capacity, a more efficient and robust orchestration of the components that facilitate air travel is required than is the case today. Over recent years, camera systems for automatic identification of ground-handli ...

Truck Routing for Parcel Delivery

Solving a Multi-depot Pickup and Delivery Problem with Occasional Drivers using ALNS

This research presents a mathematical model for routing that incorporates multiple depots, occasional drivers, and multiple depot visits, a problem faced by many companies in reality. An Adaptive Large Neighborhood Search (ALNS) algorithm was employed, using Random and Worst remo ...
The advent and rise of low-cost, high-frequency short-haul flights in Europe increasingly necessitates the need of more sustainable travel methods for trips with a distance under 1000 km. Many different proposals and policies have been put in place, including full flight bans for ...
A novel security checkpoint concept has been proposed to address the continuing growth in passenger traffic that airports are experiencing globally. The new security checkpoint intends to employ Automated Guided Vehicles (AGVs) instead of conveyor belts for baggage tray transport ...
To reduce greenhouse gas emissions in aviation, innovative propulsion systems such as battery-powered electric aviation are essential. These systems are carbon neutral when powered by 100% green electricity. However, widespread adoption requires overcoming challenges including im ...
Quad-planes combine hovering and vertical takeoff and landing capability with fast and efficient forward flight. Regular Quad-planes with dedicated pusher motor can be subject to gust disturbances, and are not well-equipped to deal with actuator faults. Dual-axis Tilt-Rotor quad- ...
Enroute Air Traffic Controllers (ATCOs) determine the appropriate course of action by scanning radar displays to identify and select a flight that requires clearances to ensure safe and efficient operations within their airspace sector. After selecting a flight of interest, ATCOs ...
In response to the growing demand for air travel, major airports are approaching critical thresholds in their infrastructure capacity. As the transportation sector continues to expand, it is increasingly important to address environmental concerns that arise from aspects, such as ...
