Leap

LEAP is a new generation aircraft engine that reduces fuel consumption and carbon emissions by 15%. It was jointly designed in a collaboration between Safran Aircraft Engines and several CNRS laboratories, including EM2C (Laboratoire Énergétique Moléculaire et Macroscopique, Combustion/molecular and macroscopic energy and combustion laboratory). The advantage of this partnership is to improve knowledge on the production of soot, which is fine particles resulting from the incomplete combustion of carbon-based fuels, to work on designing combustion chambers that are less polluting and with a lower environmental impact.
