Aviation News – Singapore will become the world’s first airport testing ground for next-generation Open Fan engine operations after the Civil Aviation Authority of Singapore (CAAS), CFM International and Airbus signed a Memorandum of Understanding to trial CFM’s Revolutionary Innovation for Sustainable Engines (RISE) technologies, aiming to prepare airports globally for cleaner, more efficient aircraft.
The agreement was formalised at the 3rd Changi Aviation Summit on 2 February 2026 by CAAS Director-General Han Kok Juan, Safran Singapore CEO David Dufrenois on behalf of CFM International, and Airbus Executive Vice-President of Engineering Rémi Maillard. The partnership will assess how Open Fan engines and other RISE programme innovations affect airport infrastructure, safety, ground handling and flight operations, positioning Singapore as a development hub and creating a readiness framework intended to guide airframers, airports and airlines worldwide.
Unlike conventional turbofan engines, the Open Fan architecture uses large, exposed blades to improve airflow and cut fuel burn and emissions significantly. The design promises double-digit efficiency gains but requires adjustments to ramp procedures, spacing, noise management and ground equipment. Trials at Changi will analyse everything from aircraft stand layout to debris protection and bolt-secure engine integration, ensuring safe and seamless operations in a busy international hub.
“By working together at a live airport environment, we can accelerate the introduction of breakthrough propulsion technologies and set global standards for sustainable aviation,” the partners said, underscoring the importance of aligning infrastructure with future aircraft designs.
