Careers at the von Karman Institute: Construct the future together!

For 65 years as international center of excellence in fluid dynamics, the von Karman Institute brings together young engineers and scientists from all over the world to study, improve their skills and perform their research.

Construct the future together! Besides its mission of education, the von Karman Institute gathers the top-level scientists and engineers to work on very challenging projects as the next generation of engines, new propulsion concepts, the new green energy, the safety of industry, solutions for a cleaner space, the Mission to Mars and many other fields of research which can make the difference for the human kind. Those scientists have access to more than 50 wind tunnels and test rigs, some of them unique in the world to help them in their projects.

VKI is a team of people looking in the same direction, for a better future, not only scientists and engineers but also students, PhD candidates, PostDocs, IT, Human Resources, accountants, librarians, designers and technicians and more....

“A scientist studies what is, whereas an engineer creates what never was“, Théodore von Kármán

PhD position to develop prediction models on noise emissions of the next generation of supersonic aircraft

A PhD position is available at the von Karman Institute for Fluid Dynamics (Rhode-St-Genèse, Belgium), in the framework of the European project More&Less (Grant Agreement No 101006856)

Start date: 1 May 2021

Duration: 3 years, full-time

Deadline Submission: 31 March 2021

About the MORE&LESS project

This project aims at verifying the compliance of novel supersonic aircraft concepts with the environmental requirements of current and next-generation civil subsonic aircraft or by assessing potential new supersonic transport standards. MORE&LESS (MDO and REgulations for Low-boom and Environmentally Sustainable Supersonic aviation) will indicate which aircraft configurations, propulsive technologies, types of fuel and trajectories and operations will help match the requirements, thus allowing for the minimum environmental impact.

About your mission

The present PhD position is focused on noise emissions, with the specific objective to develop prediction models for the next generation of supersonic aircraft. The project will comprise a strong experimental component, with extensive measurement campaigns to be performed in the anechoic laboratory of VKI, combined with modelling activities. The experiments foresee microphone array techniques and optical diagnostics (high-speed and stereoscopic PIV). Low-order models such as based on a wavepacket description of the source field, combined with an aeroacoustic analogy, will be developed and finetuned using the experimental databases. A particular attention will also be brought to near-field non-linear propagation effects, known to be responsible for the intense crackle noise perceived in the vicinity of military jet aircraft. Finally, the candidate will explore the potential of machine learning techniques to fill in the blanks where physics-based models prove unable to predict the measured sound levels.

Flight More and Less

The multidisciplinary topics addressed in MORE&LESS are scientifically challenging and of high technological and economical relevance, promising interesting career perspectives in academic and multi-sectorial industrial environments. VKI does strictly adhere to the ethical standards of the European Charter for Researchers and Code of Conduct for the Recruitment of Researchers ( . Female scientists are particularly encouraged to apply. A strict equal opportunity, gender-neutral and internationally comparable recruitment procedure is implemented.


The applicants should hold a Master degree in Mechanical Engineering, Aerospace Engineering or equivalent, with a specialization in fluid dynamics.

A background including aeroacoustics or flow stability is a strong asset.


Employed for 36 months by the von Karman Institute for Fluid Dynamics in one of the most attractive areas of central Europe in the neighborhood of Brussels.

Work at the internationally renowned von Karman Institute in a key role advancing technologies for future motor and energy systems;

Work in close collaboration with leading aeronautics and aerospace companies as well as other industries;

Become part of the VKI network with global access to industry experts and academics in the field of fluid dynamics, aerospace, aeronautics, propulsion, and energy conversion;

Experience the unique international workshop character of the VKI working environment.

Access to specialized seminars and lecture series and to world-unique facilities
