To promote the decarbonization of air transport, Emmanuel Macron announced on Friday an envelope of 300 million euros per year over the period 2024-2030 for the design of new planes and new engines. What will tomorrow’s engine look like? Europe 1 asked the Safran technicians the question.
How to decarbonize aviation? To explore the question and ahead of the opening of the Paris Air Show, the Head of State went to Villaroche, in Seine-et-Marne, on Friday to visit the Safran factory, which produces engines for civil and military aircraft. Emmanuel Macron has promised an envelope of 300 million euros per year over the period 2024-2030 for the design of new planes and new engines. The goal now: the zero-emission aircraft and especially the manufacture of a green engine still in design.
Reduction of CO2 emissions by up to 80%
“Today’s engine is two meters in diameter. The engine of tomorrow that we imagine, its blades will be four meters in diameter. We will be able to orient them”, enthuses Michel Brioude, technical director at Safran. To visualize the aircraft of the future, you have to imagine an apparent double propeller with blades in the open air, a bit like a windmill. The engine called Rise, for Revolutionary Innovation for Sustainable Engines, is the company’s new gem. And it’s designed to reduce an aircraft’s CO2 emissions by up to 80%.
“Architectural changes mean 20% reduction in consumption. And the second pillar is to use sustainable fuels, such as fuel from biomass, from oils, but it is also synthetic fuels. And there is still a third pillar, it is to use electricity which still allows us to optimize the operation of the engine”, specifies the technical director.
With the help of aircraft manufacturers, the entire short and medium haul fleet must therefore be redesigned. “With different wings, they also imagine high wings hanging from the back. It’s even very artistic”, concludes Michel Brioude. A ground test is already planned for 2025 for commercialization expected within ten years.
