Airbus A380 Flight Lab Unveiled for CFM RISE Open Fan Testing

Airbus SE and CFM International unveiled the livery for the Airbus A380 flight lab dedicated to testing the CFM RISE (Revolutionary Innovation for Sustainable Engines) Open Fan engine architecture at the Farnborough International Airshow on July 21, 2026.

The presentation coincides with the completion of the first conceptual flight test design review. The joint program between Airbus and CFM International, a 50/50 joint company between GE Aerospace and Safran Aircraft Engines, aims to reduce fuel consumption and carbon dioxide emissions by 20 percent compared to current commercial engines.

Transitioning to flight test preparation

The designated testbed aircraft, an Airbus A380 identified as Manufacturer Serial Number (MSN) 114, departed a six-year desert storage in France on July 16, 2026. The aircraft relocated to Shannon, Ireland, to undergo painting and structural modifications. Engineers will eventually mount the open fan engine in the number 2 position on the inboard left wing for the Test-Flights campaign.

CFM International recently completed the preliminary design review for the compact core system, open fan, and outlet guide vanes. Arjan Hegeman, Vice President of Future of Flight Engineering at GE Aerospace, stated that this milestone allows the Manufacturing of parts for the grounded demonstrator to begin.

Prioritizing engine durability

While the open fan design removes the traditional engine casing to accommodate a larger fan and reduce drag, program leaders are placing equal emphasis on component longevity. GE Aerospace has completed over 350 tests and 3,000 endurance cycles on core components, which includes early dust ingestion testing.

“If there’s anything we’ve learned over the last years, it’s that durability matters as much as, if not more than, fuel efficiency,” Hegeman said.

Hegeman noted that the engineering teams are aiming to reach technology readiness level six by the turn of the decade.

AirPro News analysis

The explicit focus on durability during the early testing phases of the CFM RISE program reflects a broader industry shift. Current-generation narrowbody engines have faced well-documented time-on-wing and maintenance challenges, prompting Manufacturers to prioritize robust operating characteristics alongside fuel efficiency gains. By subjecting core components to 3,000 endurance cycles and dust ingestion tests years before the first flight, CFM International is working to ensure the open fan architecture can withstand harsh operational environments from entry into service. We expect this dual mandate of efficiency and reliability to define the Certification pathway for next-generation Propulsion systems.
