Noise Abatement 3D Flight Planning Using a Snake Algorithm

The aviation industry has struggled with reducing the amount of noise that aircraft generate, especially when flying close to communities. This effort has led to the introduction of technological and operational novelties such as efficient trajectory planning. In line with these operational efforts, a tool has been designed in the TU Delft,...

Inclusion of noise-related constraints in departure procedure optimization

The ever-increasing use of aircraft, together with the on-going urbanization causes increasing noise nuisance due to aviation. This is attenuated by the positioning of airports close to densely populated areas. For this reason the majority of the large airports in the world indicate that noise is one of the limiting factors in the expansion of...

Contrail Mitigation by means of 4D Aircraft Trajectory Optimisation

Aviation has a significant impact on the global atmosphere. Next to particle and gas emissions, the increase of cloud cover might increasingly contribute to aviation induced climate change. Water contained in the exhaust of jet engines locally raises the relative humidity levels sufficiently for contrail formation to occur. These contrails can...

Evaluation of Intermediate Refueling Stops in Long-Haul Flight Operations

The aviation sector has suffered a big blow from the series of recent economic depressions. Airlines are struggling to stay in business and are looking for multiple ways to cut on expenses. This has led to the initiation of studies to find strategies which will reduce an airline’s overall fuel consumption. One of these methods is to initiate...

Optimization of Weather Adaptive Noise Abatement Trajectories

As projected air travel is expected to increase up till 2030, future airports are faced to deal with the impact of (rising) noise hinder within their environment and the resulting allowed attainable throughput capacity. To date, several proposed techniques are able to lower the noise contribution. This thesis study focusses on weather-adaptive...

A Low Emissions Taxi Movement Planning Tool

The goal of this research project was to develop and test an online, automated taxi movement planning tool, that optimizes the timed taxiing routes of all aircraft on an airport, by minimizing the impact on the environment. Automatic taxi planning tools have been developed before, but the emissions have never been included before as a factor in...

Multidisciplinary Design Optimization in the Conceptual Design Phase: Creating a Conceptual Design of the Blended Wing-Body with the BLISS Optimization Strategy

Traditionally, the aircraft design process is divided into three phases: conceptual, preliminary and detailed design. In each subsequent phase, the fidelity of the analysis tools increases and more and more details of the design geometry are frozen. In each phase a number of design variants is generated, fully analyzing them with the tools...
