Horizontal Tail and Aileron Sizing for Distributed Electric Propulsion Aircraft

The concept of Distributed Electric Propulsion (DEP) aircraft holds great promise in achieving the goals outlined in Flightpath 2050. This involves utilizing electricity to power propellers and enhancing overall flight performance through interactions between the wings and propellers. This thesis investigates the stability and control aspects of...

A Framework for Collaborative Front-Loaded Design Space Exploration: Improving collaboration across the aeronautical supply chain

In the conceptual design phase, OEMs perform technology assessment to identify feasible solutions for their new aircraft. When the OEM is unable to assess a certain technology themselves, they consult Tier-1 suppliers to involve<br/>them in the design process. The suppliers have higher fidelity analysis tools that can help the OEM with their...

Design of future ultra-high bypass ratio turbofans: A synergy of low-NOx combustion technologies

Weight estimation for pylons supporting large aero-engines: A KBE approach

The aviation industry confronts challenges from increased air traffic and environmental concerns. Enhancing engine efficiency becomes crucial due to persistent greenhouse gas emissions from air travel, particularly in long flights with high CO2 emissions. Higher by-pass ratios (BPR) can address this by boosting engine propulsive efficiency, yet...

Aeroacoustics of Airborne Wind Energy Systems

Airborne wind energy systems offer a promising approach for renewable energy generation. However, the noise emissions associated with these systems should be understood and minimized as well to promote their integration and (social) acceptance. This research aims to identify the noise sources of airborne wind energy systems, systems with leading...

Improving Stall Model Accuracy through Optimal Data Slicing by Analyzing Kirchhoff Stall Parameter Estimate Behaviour

To improve the safety of commercial air transport, pilots are required to train on simulators to recognize the characteristics of an impeding stall and subsequently correctly recover from it. To prevent negative training, it is important that the accuracy of the used simulation models is high. A manner to model the nonlinear, unsteady...

Towards Computationally Efficient Coupled Propeller-Wing Optimisation

Much like the oil crisis in the 1980s, the aviation industry is once again considering more environmentally sustainable propulsion options due to concerns around climate change. More fuel efficient propulsion methods form the pillar on which environmentally sustainable aviation can be built, since it is the propulsion system that emits harmful...

Collaborative Knowledge Based Engineering

Present Knowledge Based Engineering (KBE) applications do not facilitate collaborative processes due to lack of process formalization and orchestration capabilities, leading to ad-hoc solutions. This increases application development time, reduces re-usability, and increases the cognitive burden of users leading to decreased design efficiency....

Design and Feasibility of a 30- To 40-Knot Emission-Free Ferry

Internal combustion engine (ICE) emissions cause numerous social, environmental, health, and economic issues, including extreme weather or harm to public health. These effects are also experienced in the Chinese Pearl River Delta, where a high-speed, 200-passenger ferry named the Coastal Cruiser 200 (CC-200) uses ICEs to operate. The CC-200's...

Study to the adaptation of electrified aircraft by regional airlines: using strategic airline planning and aircraft design

To reduce the environmental impact of the aviation sector in Europe, climate goals have been set as stated in the Paris Agreement and the European Green Deal. This reduction can be achieved by fleet replacement with electrified aircraft. Challenging is that electrified aircraft are yet in a conceptual phase and most likely suitable for smaller...

Evaluation of the overall installation penalty of aero-engines for single aisle aircraft: A comparison between engine retro-fit and aircraft redesign

The past 70 years has shown an incredible growth in air transport. The increase in flights has resulted in an increased strain on the environment. Climate change is a fact. Designers have been working on improving the aircraft, and in particular, the engine efficiency. By improving the internal components through better materials, new design...

Advisory System for MDO Architecture Selection in the MDO System Formulation Stage

One of the challenges in executing an MDO system is the selection of the best performing MDO architecture in terms of computational effort for a given MDO problem. To address this, several comparative studies have been created, which analyze the relative performance of MDO architectures with respect to internal features of MDO problems, such as...

An aerodynamic analysis of Hyperloop breach using a scaled physical test setup and background oriented schlieren

This master thesis investigates the aerodynamic response of the Hyperloop breach failure scenario. Using a scaled physical test setup, the air pressure inside a Hyperloop tube is lowered to 10 mbar, emulating Hyperloop conditions. By opening a breach hole inside the tube, air will flow into the tube due to the pressure difference with the...

An inter-comparison of the climate impact of short-, medium-, and long-range aircraft

Aviation has a growing impact on the earth’s climate, due to its emissions causing an increase in the global near-surface temperature. In order to better understand the dynamics by which different aircraft types contribute to this global warming and how this can be mitigated, the impact of different aircraft categories is analysed and compared....
