The 3AF International Conference on Applied Aerodynamics is an annual event organised by the French Aeronautics and Aerospace Society (3AF) at French venues between researchers of all nations leading an activity in aeronautics or aerospace.

It is an excellent opportunity for scientific exchanges between researchers from industry, research institutions and academia. Researchers from other fields are also welcome as the current theme englobes the whole transport and energy sector.

Each year the conference addresses a particular topic in aerodynamics. It is organised on the basis of five half-days of technical presentations, each introduced by a keynote conference from a recognised expert and is concluded by a technical tour in connection with the conference theme.

This 56th Edition hosted by the “Département d’Aérodynamique, Énergétique et Propulsion” (DAEP) at ISAE-SUPAERO intends to gather experts in diverse fields to share their perspectives on Aerodynamics for Lower Environmental Impact. Scientific evidence of the impact of noxious gases on the environment has been present for almost five decades; however, measures for reduction are being enforced only recently following the declaration of a climate emergency.

Consequently, serious questions are being asked about the contribution from aviation, which accounts for less than 5% of the overall emission. Regardless of the sharp drop in flights due to the recent pandemic, a growth in aviation industryis still forecasted and thus raising back concerns of its impact on our climate. The increased number of flights taking-off and approaching urban areas has also raised questions of noise levels. Noteworthy progress has been made through improvements of traditional configurations and emergence of a variety of novel architectures. Hydrogen and electric propulsion are slowly paving their way in small scale applications, but improvement in aerodynamic efficiency through better design can accelerate the implementation of these technologies at larger scale. The design and optimisation of these novel concepts are enabled through more accurate representation of the physics from experiments and our ability to simulate complex systems for larger parameter spaces using more advanced algorithms. Novel mobility systems are attempting to redefine intra and inter urban transportation using unmanned aerial systems. Coupled with the emergence of micro-air systems we are being encouraged to revisit low Reynolds number flows while seeking inspiration from nature. The real impact of emission can be assessed with further understanding of contrails and dispersion of emissions through atmospheric and geophysical fluid dynamics studies.

The aviation industry has seen tremendous growth, but we are currently transiting into a new era in which its future needs to be redefined. Assessment of the environmental impact is also a major concern for terrestrial vehicles, in particular through there duction of aerodynamic drag. Buildings are also concerned through ventilation and heating systems, which can impact on covid-19 transmission.
