\u201cReduce emissions\u201d is the new dogma whatever the means of transport envisaged: car, boat, helicopter \u2026 Airplanes, of course, are no exception in the industrial challenge of the 21st century.<\/p>\n
The complete lifecycle of the aircraft must be reviewed with an eco-responsible approach. The \u201cecologically sustainable\u201d value becomes a major criterion in the choices of design, industrialization, manufacturing, and operations of the aircraft, just like traditional values <\/strong>\u200b\u200b<\/strong>such as performance or cost.<\/strong><\/p>\n Let us briefly review some guidelines that could limit the environmental impact of an aircraft throughout its lifecycle.<\/p>\n <\/p>\n The first axis concerns the optimization of\u00a0the overall aircraft architecture<\/strong>, for example the fuselage shape, the engines location, the airfoils shape, or the choice of on-board systems that consume few energy.<\/p>\n Then, the recurring battle in aeronautics consists in reducing\u00a0the weight<\/strong>\u00a0of the aircraft through the choice of efficient materials such as new light metallic alloys or new innovative composites.<\/p>\n In addition, optimizing\u00a0the aerodynamics of both fixed and moving airfoils<\/strong>, such as the wings and wing tips, will help to maximize laminar flow.<\/p>\n Last but not least, the greatest impact on the carbon footprint relies on the choice of\u00a0the propulsion system<\/strong>. Several choices are considered:<\/p>\n \u00a0<\/strong><\/p>\n The manufacturing of a green aircraft involves the development of\u00a0a green industrial system<\/strong>, not only respectful of its consumptions and emissions in its choice of infrastructure and its facilities, but also by the choice of its\u00a0supply chain: one could imagine the selection of suppliers based on \u201cgreen\u201d criteria, the limitation of flows across countries, local supply, etc.<\/p>\nThe green Aircraft in the Design phase<\/strong><\/h2>\n
