SINGAPORE — Singapore has taken a major step toward shaping the future of sustainable aviation, announcing plans to host the world’s first airport-based testbed dedicated to next-generation Open Fan aircraft engine technology. The initiative positions the city-state as a global proving ground for propulsion systems that could deliver more than 20 percent fuel efficiency gains in future commercial aircraft.
The effort is anchored by a new Memorandum of Understanding signed on February 2, 2026, at the third Changi Aviation Summit. The agreement brings together the Civil Aviation Authority of Singapore, CFM International, and Airbus in a collaboration designed to move advanced propulsion concepts from research environments into real-world airport operations.
Testing activities under the partnership are planned at Changi Airport (SIN) and Seletar Airport (XSP), two facilities that together offer a mix of large-scale commercial and specialized aviation operations.
Focus on Open Fan Propulsion Technology
At the center of the collaboration is CFM International’s RISE technology demonstration program, which is intended to define the propulsion architecture for the next generation of narrowbody aircraft. A key feature of the RISE program is the Open Fan engine architecture, which removes the traditional nacelle surrounding today’s turbofan engines.
By eliminating the casing, the Open Fan design enables a larger fan diameter, improving propulsive efficiency while reducing aerodynamic drag. CFM designed the RISE program to deliver more than 20 percent improvement in fuel efficiency compared with today’s in-service commercial engines.
Beyond fuel savings, the Open Fan architecture is intended to support lower carbon emissions, reduced noise footprints around airports, and compatibility with future hybrid-electric systems. Industry participants view the technology as a foundational element in long-term efforts to decarbonize air transport.
Moving Beyond the Test Aircraft
While Open Fan engines have been studied in laboratories and flight-test environments, the Singapore initiative is designed to address a different challenge: airport readiness. By establishing Singapore as the primary testing ground, the partners aim to understand how such engines interact with daily airport operations.
That includes examining implications for aircraft movement areas, ground handling, maintenance workflows, and turnaround processes. The objective is to identify operational, safety, and infrastructure considerations early, well before the technology enters commercial service.
The initiative reflects a growing recognition across the aviation industry that propulsion breakthroughs must be matched by changes across the broader airport ecosystem.
Developing an Airport Readiness Framework
Under the MOU, the three parties will jointly develop a comprehensive airport readiness framework to support the integration of Open Fan engines into existing aviation systems. The framework will address aircraft design considerations, infrastructure requirements, operational procedures, safety standards, and regulatory approval pathways.
Singapore’s aviation ecosystem will play a central role, contributing expertise in airport planning, safety oversight, and regulatory development. The intent is to produce a globally applicable blueprint that airports, airlines, and manufacturers can reference as they prepare for next-generation propulsion technologies.
The partners also plan to conduct operational trials using RISE Open Fan engine demonstrators at either Changi or Seletar. These trials will be used to validate the readiness framework and assess the feasibility of deploying Open Fan-equipped aircraft in active airport environments rather than controlled test settings.
Industry Leadership Perspectives
CAAS Director-General Han Kok Juan noted that the testbed will allow companies to develop real-world protocols that can support large-scale global deployment of new propulsion technologies.
Airbus Executive Vice-President Engineering for the Commercial Aircraft business, Remi Maillard, said the partnership will help mature future propulsion systems by testing them against operational requirements. He added that Singapore’s advanced aerospace ecosystem makes it an ideal environment to support Airbus’s long-term commitment to sustainable aviation.
Global Implications for Aviation
The initiative places Singapore at the center of global efforts to prepare airports for the next era of aircraft propulsion. While the testing will take place locally, the outcomes are expected to influence airport and airline planning worldwide.
As manufacturers push toward lower emissions and higher efficiency, the availability of a proven, airport-tested framework could accelerate adoption of Open Fan and other advanced propulsion systems across the global fleet.
Bottom Line
Singapore’s decision to establish the world’s first airport testbed for Open Fan propulsion technology marks a significant milestone in aviation innovation. The partnership between the Civil Aviation Authority of Singapore, CFM International, and Airbus is expected to yield a transferable blueprint that helps the industry prepare for aircraft capable of delivering more than 20 percent fuel efficiency improvements.
As the commercial aviation sector intensifies its focus on sustainability, Singapore’s testbed positions the country as a critical reference hub for the next generation of aircraft propulsion.
