CFM International, a leading aircraft engine manufacturer, has announced significant progress in its Revolutionary Innovation for Sustainable Engines (RISE) technology program. The program unveiled two years ago, aims to develop advanced technologies for more sustainable aviation and achieve the industry’s goal of net-zero emissions by 2050. CFM has completed over 100 tests as part of the RISE program, which includes the development of innovative engine architectures, combustion technology, thermal management, and hybrid electric systems.
One of the key advancements made through the RISE program is the open fan architecture, which has demonstrated improved propulsive efficiency and favorable noise level performance. CFM is targeting more than 20% better fuel efficiency and 20% lower CO2 emissions compared to the most efficient engines currently in service. The program also focuses on meeting stringent non-CO2 and noise emission requirements.
