Aircraft noise modelling and climate effects of aviation
For this vacant position, please indicate which of the following two profiles interests you.
Profile 1: Aircraft Noise Modelling
With the continuous growth of global air traffic, aircraft noise has a significant environmental impact, especially around airports, and is a source of disturbance to the public. For this aviation growth to be sustainable with a decreasing impact on the environment, more accurate models for the prediction of the noise footprint are required. Your job will focus on the acoustic modelling of aircraft noise, related to both the engines and the airframe. These aircraft noise models range from fully numerical to parametric semi-empirical. In addition, you will be involved in the designing and executing of acoustic experiments and the corresponding data analysis, both for operational conditions and in wind tunnels. You will further improve aircraft noise models, both for existing aircraft and new aircraft technologies. Also, you will work on the application and validation of state-of-the-art aircraft noise models, including the trajectory computation, for existing and novel operational procedures.
Profile 2: Climate Effects of Aviation
Aviation contributes significantly to climate change due to the emission of CO2, but even more importantly due to non-CO2 effects, such as the formation of contrails and emissions of nitrogen oxides, water vapour, and particles. Your job will mainly focus on developing and assessing technological and operational solutions to significantly reduce aviation’s climate impact from CO2 and these non-CO2 effects.
This eventually facilitates a climate compatible air transportation system in an eco-efficient manner. The basis of your work will be numerical modelling to investigate climate mitigation options. The applied models range from physically and chemically based Earth-System models, including a detailed description of aviation, to fast response models which are used to assess, e.g., a large number of aircraft design options. Earth-System modelling is enabled by supercomputing and is a highly interdependent modelling approach which requires dedicated diagnostic tools to identify atmospheric responses. In addition, data analysis techniques are used to extract atmospheric responses due to aviation from the big amount of data produced.
A Tenure Track, a process leading up to a permanent appointment with the prospect of becoming an Associate or full Professor, offers young, talented academics a clear and attractive career path. During the Tenure Track, you will have the opportunity to develop into an internationally acknowledged and recognised academic. We offer a structured career and personal development programme designed to offer individual academics as much support as possible. For more information about the Tenure Track and the personal development programme, please visit www.tudelft.nl/tenuretrack.
The candidate should have a PhD degree in an area relevant to the subject, e.g. aerospace engineering, (applied) physics, applied mathematics or atmospheric sciences. A combination of excellent mathematical skills and a solid knowledge of signal processing is required. Advanced programming skills and a strong interest in high-performance computing are also essential. An outstanding research potential and having published in leading international scientific journals is mandatory for this position. You have demonstrated the ability to initiate and direct research projects and to obtain external funding. Also, you have an active international network of scientific contacts. The candidate should have an open personality and good communication skills in written and spoken English.
Delft University of Technology (the TU Delft) is a multifaceted institution offering education and carrying out research in the technical sciences at an internationally recognised level. Education, research and design are strongly oriented towards applicability. The TU Delft develops technologies for future generations, focusing on sustainability, safety and economic vitality. At the TU Delft you will work in an environment where technical sciences and society converge. The TU Delft comprises eight faculties, unique laboratories, research institutes and schools.
The mission of the Department of Control and Operations is to improve the safety and efficiency of operations in aerospace and to reduce their impact on the environment. The department comprises three sections: Control and Simulation, which focuses on the development of advanced automatic control systems (including the role of the human operator), Air Transport Operations, which aims to improve operational performance in terms of capacity, safety, and economy, and Aircraft Noise and Climate Effects, which focuses on reducing aircraft noise, emissions, and the effects of aviation on climate change.
The Aircraft Noise and Climate Effects (ANCE) section focuses on modelling the effects of aviation on the environment with respect to noise and emissions. The section works on detailed aircraft noise source modelling, considering both the engines and airframe, e.g. for the assessment of new aircraft technologies. The section develops models capable of assessing the aviation-induced climate effects by calculating the contribution of individual climate agents such as carbon dioxide and ozone. This enables assessing the effectiveness of mitigation measures such as climate-optimised routing.
