Webinaire SF2M (in English)
Circular economy in the aviation sector
En 2025, la SF2M fêtera son quatre-vingtième anniversaire !
Pour rendre hommage à cette grande dame d’âge respectable, une large panoplie de manifestations sera proposée à toute la communauté des matériaux.
Dès le mois de septembre 2024, nous vous proposons des Webinaires SF2M, une action que nous souhaitons pérenne. D’une périodicité définie (1 à 2 webinaires par mois), occupant sauf exception un créneau fixe (2ème et 4ème mardi du mois, 13h-14h), accessibles sur plateforme de visioconférences, les Webinaires balayeront tous les matériaux (métaux, céramiques, polymères.… multimatériaux et composites, …) et présenteront des visions industrielles et des progrès scientifiques récents. Nos ferons appel à des conférenciers expérimentés et à de jeunes talents, hommes et femmes. Nous mettrons en valeur les matériaux et notre communauté… ainsi que la SF2M !
Ce seizième webinaire de 2025 aura pour thème « Circular economy in the aviation sector ». Il sera présenté en anglais par Stefan DRAWIN. Il aura lieu le mardi 4 novembre de 13h à 14h. Un lien vers la plateforme du webinaire vous sera envoyé peu avant la présentation.

Résumé du webinaire
Air transport is a sector that has long applied the principles of the circular economy on a large scale: seeking to reduce aircraft weight (reducing the quantity of raw materials used), seeking to reduce fuel consumption (reducing the quantity of fossil fuels used), reducing emissions (CO2, nitrogen oxides, soot, etc.) and noise, in particular by optimising aerodynamics, engines and air traffic, increasing the service life of aircraft structures and various systems (engines, avionics, etc.) through strict overhaul and maintenance programmes, reuse, recycling or various forms of recovery of aircraft components that have reached the end of their service life, etc..
The environmental footprint of an aeroplane is nevertheless higher than that of a bicycle, but these two modes of transport do not meet the same needs. Their social acceptability has evolved. Proportionally speaking, more than 95% of an aeroplane’s environmental footprint is due to its operational phase (greenhouse gas emissions linked mainly to the combustion of kerosene, for example), whereas for bicycles, it is the manufacturing phase that is mainly responsible.
What is the lifespan of an aircraft? Why is an aircraft taken out of service? Can an aircraft have a second life? And what happens to it when it reaches the end of its life? This presentation will examine these issues and discuss current approaches to reducing the environmental footprint of the phases preceding and following the operational phase of these aircraft.
Conférencier : Stefan DRAWIN, ONERA. Stefan Drawin holds a PhD in atomic and molecular physics He is working at ONERA, the French national aerospace research center, since 1990. He has investigated various types of high temperature materials and applications: composite thermal shields for protection of space shuttle during atmospheric reentry, zirconia-based thermal barrier coatings for turbine applications, Ni-based superalloys as well as refractory metal based silicide materials for aeroengine hot section applications. For the latter, he has coordinated two European projects dedicated to alloy definition, manufacturing and characterisation. Since 2010, he is active in the development of powder metallurgy, especially with the procurement of an EIGA/VIGA gas atomisation facility, with the production, characterisation and application of metallic powders. More recently, he is involved in the development of circular economy in the aviation sector, at ONERA and in the frame of EREA, the European Association of Research Establishments in Aeronautics. |
