RISE: A TECHNOLOGY DEVELOPMENT PROGRAM FOR A NEW GENERATION OF SUSTAINABLE AIRCRAFT ENGINES
■ TogetherwithitspartnerGE,Safranannounced,on June 14, 2021 that it was launching an ambitious program to develop the technology for an upcoming generation of aircraft engines designed to burn 20% less fuel than the new-generation LEAP engine and be 100% compatible with sustainable aviation fuels as well as hydrogen. By combining these two major advances, planes powered by the future engine will be able to slash CO2 emissions by more than 80%.
■ As part of the new program, dubbed RISE (Revolutionary Innovation for Sustainable Engines), Safran will develop the disruptive technologies required for the new sustainable engine, which could enter service on next-generation aircraft towards the middle of the next decade. With an unducted fan architecture and a fan diameter twice that of the current LEAP, the new engine will deliver maximum propulsion efficiency. It will also integrate a wealth of state-of-the-art technologies, from new materials such as alloys and composites offering very high- temperature resistance and substantially reduced weight, to hybrid electric layouts – a first for a commercial aircraft engine – and innovative production processes such as additive manufacturing, which requires fewer raw materials and allows for the creation of lighter parts.
■ Through the RISE program, Safran and GE are investing in a unique array of disruptive technologies to develop a state-of-the-art engine that will power the decarbonized commercial aircraft of the future.
