Can Singapore's new airport testbed safely launch CFM's revolutionary Open Fan engine?
Aviation News Editor & Industry Analyst delivering clear coverage for a worldwide audience.
CAAS, CFM International, and Airbus established the world's first airport testbed in Singapore to study the operational impact of the fuel-efficient RISE Open Fan engine.
Key Takeaways
- •CAAS, CFM International, and Airbus established the world's first airport testbed in Singapore for CFM's RISE Open Fan engine architecture.
- •The RISE program targets over 20% better fuel efficiency and lower CO2 emissions than today's most advanced commercial engines.
- •The testbed will co-develop a 'comprehensive readiness framework' to address operational challenges, including ground clearance, infrastructure, and safety protocols.
- •Operational trials of the Open Fan demonstrator are planned for Singapore Changi or Seletar airports later this decade.
The Civil Aviation Authority of Singapore (CAAS), CFM International, and Airbus have launched a landmark partnership. They will establish the world’s first airport testbed dedicated to next-generation propulsion technologies in Singapore.
This collaboration focuses on CFM’s Revolutionary Innovation for Sustainable Engines (RISE) program. Specifically, it will study the operational impact of the radical Open Fan engine architecture.
The Memorandum of Understanding (MOU) was signed on February 2, 2026, at the 3rd Changi Aviation Summit.
The Open Fan Engine and RISE Program
The RISE program is a technology demonstrator. It aims to develop a successor to today's high-bypass turbofan engines.
CFM International, a joint venture between GE Aerospace and Safran Aircraft Engines, targets a 20% improvement in fuel efficiency and lower CO2 emissions.
The Open Fan design removes the traditional engine casing, or nacelle. This allows for a much larger fan size and a higher bypass ratio.
This architecture maximizes propulsive efficiency. It is also designed for compatibility with Sustainable Aviation Fuel (SAF) and future hybrid-electric systems.
Airbus views the Open Fan as a preferred technology. It could power their next-generation single-aisle aircraft.
Developing a Global Blueprint
The core goal of the Singapore airport testbed is to create a comprehensive readiness framework. This framework will serve as a global blueprint for airframers, airports, and airlines.
The framework will address key challenges posed by the large, uncased Open Fan design. These challenges include:
- Aircraft System and Design: Ensuring proper ground clearance for the large rotor.
- Infrastructure Modifications: Assessing if changes are needed at gates or taxiways.
- Operational Procedures: Reviewing ground handling, maintenance, and safety protocols.
- Regulatory Processes: Establishing new safety standards and certification procedures.
Singapore’s Changi Airport (SIN) or Seletar Airport (XSP) will host the operational trials.
These trials are expected to occur later this decade, possibly around 2029 or 2030. They may involve a converted Airbus A380 demonstrator aircraft.
Industry Impact and Challenges
The Open Fan architecture represents a significant shift in jet engine design. It promises major environmental benefits.
However, the exposed fan blades raise operational questions. Concerns include foreign object damage (FOD) and noise.
CFM and Airbus are confident these issues are manageable. They report that the noise levels should be comparable to the current CFM LEAP engine.
The collaboration leverages Singapore's strong regulatory expertise. The Civil Aviation Authority of Singapore (CAAS) aims to position the nation as a global aerospace innovation hub.
This real-world testing environment is crucial. It will build confidence among global airlines and regulators.
Successfully integrating the CFM RISE Open Fan into airport operations is vital. It is a necessary step before the technology can enter commercial service.
The partnership ensures that next-generation aircraft are not only efficient in the air but also practical and safe on the ground. This holistic approach accelerates the industry's net-zero carbon ambitions.
- Key Entities: The partnership includes CAAS, CFM International, and Airbus.
- Technology Goal: The RISE program targets over 20% better fuel efficiency than current engines.
- Operational Focus: The testbed will address ground clearance, safety, and infrastructure needs for the large Open Fan.
- Global Outcome: The work will produce a global readiness blueprint for future narrow-body aircraft.
