Singapore Airport to Serve as Test Site for CFM’s Advanced Open Fan Engines
Pioneering Aviation Innovation in Singapore
Singapore is set to become the first country in the world to establish an airport test site for advanced open fan aircraft engines developed by CFM International, marking a significant milestone in global aviation technology. The Civil Aviation Authority of Singapore (CAAS) formalized this initiative by signing a memorandum of understanding with Airbus and CFM at the Changi Aviation Summit on February 2. This agreement positions Singapore as a key proving ground for CFM’s Revolutionary Innovation for Sustainable Engines (Rise) program, which aims to revolutionize aircraft propulsion.
The next-generation engines under development promise to enhance fuel efficiency and reduce emissions by up to 20 percent compared to current jet engines. The collaboration seeks to create a comprehensive framework for integrating these engines into airport operations, with research focusing on their effects on infrastructure, operational procedures, safety protocols, and regulatory compliance.
Han Kok Juan, director-general of CAAS, emphasized Singapore’s strategic role as an integrated air hub with strong regulatory capabilities. He noted that the partnership enables companies to test and refine technologies while developing real-world protocols for global deployment. Although the timeline for engine testing remains undecided, Han indicated that trials could be conducted at either Changi or Seletar airports and may extend over several years.
The Rise Program and Open Fan Technology
Launched in 2021, CFM’s Rise program centers on open fan turbine technology, which combines elements of propeller and turbofan engines. Unlike traditional jet engines enclosed within a casing, open fan designs increase airflow and reduce noise levels. These engines are also being engineered to support hybrid-electric propulsion systems and alternative fuels, including hydrogen and sustainable aviation fuel. CFM aims to bring these engines to market by the mid-2030s.
Singapore’s selection as a test site aligns with its broader ambition to establish itself as a global aerospace innovation hub. This initiative is expected to attract further investment and technological advancements within the sector. However, integrating open fan engines presents challenges, such as ensuring regulatory compliance, adapting airport infrastructure, and maintaining stringent safety standards.
Industry Impact and Future Prospects
Market response to the announcement has been positive, with airlines expressing growing interest in adopting advanced open fan engines to meet sustainability targets. The progress made by CFM may also prompt competitors to accelerate their own engine development programs.
Han highlighted the potential of this technology, stating, “If it works, it will be a cornerstone technology for the future of air travel, especially for the next generation of commercial narrow-body aircraft.” Narrow-body jets, which constitute over 60 percent of the global airliner fleet, are expected to benefit most from these advancements.
CFM International, a joint venture between France’s Safran and US-based GE Aerospace, is a leading manufacturer of aircraft engines. The Changi Aviation Summit, held on February 1 and 2 ahead of the Singapore Airshow 2026, convened approximately 350 government and industry leaders from more than 50 countries to discuss the future trajectory of aviation.
