RISE program of sustainable aviation engines on the way to ground and flight tests

Two years after launching one of the aviation industry’s most comprehensive technology demonstrator programs for a more sustainable future of flight, CFM International has completed more than 100 tests as a part of its Revolutionary Innovation for Sustainable Engines (RISE) technology program. Through the RISE program, CFM is advancing a suite of pioneering technologies, including advanced engine architectures such as open fan, compact core, advanced combustion technology, thermal management, and hybrid electrical systems to be 100% compatible with sustainable aviation fuel (SAF). In addition, new technologies are also being matured to test the direct combustion of hydrogen. Testing to date has helped to validate the new open fan architecture for increased propulsive efficiency, with initial tests showing positive noise level performance. The CFM RISE program targets greater than 20% fuel efficiency with 20% lower carbon dioxide emissions compared to the most efficient engines in service today. Technologies are also being validated to meet the most stringent noise and non-CO2 emission requirements. “The RISE program was launched as the absolute manifestation of our deep commitment to pushing the boundaries of innovation and delivering breakthrough technologies that will help achieve our most aggressive sustainability goals in support of the industry promise of net zero by 2050”, said Gaël Méheust, President and CEO of CFM International. “Our global team of engineers has accomplished incredible things, and I am more convinced than ever that our RISE program will deliver the propulsion technologies that will set even higher standards for our industry”, he concluded. – https://aeroin.net/programa-rise-de-motores-sustentaveis-de-aviacao-a-caminho-de-testes-de-solo-e-voo/
