This summer school will provide participants with an opportunity to learn about the various aspects of acoustics for small aircraft, drones and flying cabs, which will be operating in urban environments in the near future, based on the latest advances in the field. The aim is to provide a global vision, underpinned by a good understanding of the physical phenomena involved, so as to be in a position to propose approaches limiting the noise nuisance associated with this new technology, directly linked to the development of electric propulsion. In addition to a general contextualization addressing strategic and societal issues, this includes various aspects, such as the mechanisms of aerodynamic noise generation and propagation in urban environments at medium distance, predictive methods, experimental noise characterization, aeroacoustic reduction and optimization techniques.

The total lecture time, including practical activities, is of 24 hours, 3 hours per half day.  All courses are taught in English.

A minimum background in linear acoustics, signal processing and fluid dynamics is required to address aeroacoustic mechanisms. A short introduction or reminder of basic notions will be proposed. In the logic of applications to drones and urban air vehicles, the scope of the lectures is restricted to subsonic flows. Practical implementation of simple prediction models is also planned, starting from preliminary Matlab scripts at attendees’ disposal.
