Airbus Advances A380 Transformation as COMPANION Project Approaches Critical Design Phase
Toulouse, France — Within the next twelve months, a superjumbo like no other will touch down at Airbus’s home base in Toulouse. The aircraft in question, a former Malaysia Airlines A380 bearing manufacturer serial number 114, is destined to undergo a metamorphosis that will leave it unrecognizable from any commercial variant ever built. It represents the centerpiece of a bold European initiative to validate the propulsion technologies that could power the next generation of narrowbody aircraft.
The transformation is being orchestrated under a €25.7 million EU-funded project known as COMPANION, an acronym for the collaborative effort to establish a common flight-test demonstrator platform for ultra-efficient propulsion systems. Having commenced in January 2024, the initiative is now approaching its design freeze milestone, marking a pivotal moment in European aviation’s push toward decarbonization.
A Second Life for the Hundredth Superjumbo
MSN114 holds a unique distinction in aviation history: it was the hundredth A380 to roll off the Toulouse production line. Delivered to Malaysia Airlines as 9M-MNF in March 2013, the quad-jet served the carrier faithfully until the pandemic prompted the airline to ground its entire superjumbo fleet in 2020. After unsuccessful attempts to find a buyer, Malaysia Airlines reached an agreement with Airbus to return the aircraft as part of a broader deal involving the purchase of A330-900neo widebodies.
The superjumbo departed Kuala Lumpur in December 2022, ferrying to long-term storage at Tarmac Aerosave’s facility in Tarbes-Lourdes-Pyrénées. There it sat for nearly three years until September 2025, when tracking services detected it performing rejected takeoff procedures. Days later, registered under its new Guernsey identity as 2-JAYN and now owned by Airbus Financial Services, the aircraft completed a maintenance test flight reaching 43,000 feet before positioning onward for heavy maintenance work.
Stephane Perrin Decroux, who heads propulsion of tomorrow flight-test demonstrators at Airbus, explained why the manufacturer selected this particular airframe over its original prototype. “Starting with an aircraft already 20 years old was deemed too risky,” he noted, referring to MSN1, which first flew in April 2005. At just twelve years old, MSN114 offers decades of useful service life ahead—a critical consideration for a platform intended to support propulsion development well into the 2040s.
The RISE of Open-Fan Technology
The A380’s inaugural assignment as a flying testbed will be nothing short of revolutionary. Mounted in the number two engine position, where one of the aircraft’s Rolls-Royce Trent 900 powerplants would normally reside, engineers will install CFM International’s RISE open-fan demonstrator. The configuration will give the superjumbo an unprecedented asymmetric profile, sporting three conventional ducted engines alongside a radical unducted design featuring composite fan blades exceeding 1.6 meters in length.
CFM International, the fifty-fifty joint venture between GE Aerospace and Safran Aircraft Engines, launched its Revolutionary Innovation for Sustainable Engines program in June 2021 with ambitious targets. The open-fan architecture promises to deliver fuel consumption reductions exceeding 20 percent compared to today’s most efficient narrowbody powerplants, while maintaining cruise speeds up to Mach 0.8—comparable to current single-aisle jets.
The design dispenses entirely with the nacelle that encases conventional turbofan engines. By eliminating this cowling, engineers can implement larger fan diameters that dramatically improve propulsive efficiency. Variable-pitch carbon fiber blades, manufactured using advanced three-dimensional resin transfer molding techniques, rotate ahead of a row of static guide vanes that can adjust their angle to redirect airflow. In certain configurations, these stators can close almost completely, functioning as an air brake and potentially eliminating the need for traditional thrust reversers.
Wind tunnel testing has been underway since early 2024 at the French national aerospace research agency ONERA’s facilities in Modane, using one-fifth-scale demonstrators. According to Safran’s Pierre Cottenceau, approximately two-thirds of the planned 200 hours of testing have been completed, with results exceeding initial predictions. Full-scale ground testing of the demonstrator engine is expected to commence later this decade.
Protecting Against the Unconventional
The absence of a nacelle introduces engineering challenges that ducted engines never face. Without containment rings, an unducted fan blade release poses unique risks to the surrounding airframe. Perrin Decroux confirmed that Airbus engineers have developed what he termed a “robust shielding concept” involving additional aluminum panels installed atop the fuselage to deflect potential debris.
Whether these protective measures will be implemented depends on ongoing vulnerability studies analyzing the potential size and trajectories of any released components. The A380’s generous ground clearance and four-engine configuration make it particularly suited for such experimental work. The aircraft holds certification for ferry flights on three engines, meaning thrust from the number two position isn’t essential for flight safety—an important consideration when testing unproven powerplants.
This isn’t the first time the superjumbo has served as an airborne laboratory. MSN1 previously tested the Rolls-Royce Trent XWB-97, the most powerful engine ever developed for an Airbus aircraft, years before it entered service on the A350-1000. That particular demonstrator was housed in a distinctive pink nacelle that became something of an aviation celebrity in its own right.
A Platform for Multiple Pathways
While the RISE demonstrator will be first to fly on the modified superjumbo, the platform is designed to accommodate multiple propulsion concepts. Approximately twelve months after initial open-fan testing commences, Airbus plans to install a hybridized version of Pratt & Whitney’s PW1100G geared turbofan engine.
This powerplant is being developed through the SWITCH consortium, led by Germany’s MTU Aero Engines and funded under the EU’s Clean Aviation program. The Sustainable Water-Injecting Turbofan Comprising Hybrid-Electrics project originally aimed to combine water-enhanced turbofan technology with hybrid-electric propulsion elements, targeting fuel efficiency improvements of up to 25 percent compared to current narrowbody engines.
However, MTU announced earlier this year that it would pivot its contribution away from steam-injection technology, instead focusing on heat-recuperation approaches. The consortium has received approval from Clean Aviation to extend its first project phase by one year to the end of 2026. Flight testing aboard the A380 would form part of a potential follow-on phase, contingent on successful ground testing and continued funding through Clean Aviation’s forthcoming call for proposals.
The flight-test instrumentation being developed under COMPANION will support measurement of multiple performance parameters across both engine architectures, including aerodynamics, loads, noise characteristics, and emissions profiles. This standardized approach allows Airbus to evaluate competing technologies using consistent methodologies, generating data that will inform decisions on the propulsion systems for its next-generation single-aisle aircraft.
Airbus has indicated that its A320 family successor, dubbed the Next-Generation Single-Aisle, could enter service in the second half of the 2030s. Speaking at the 2025 Airbus Summit, company executives outlined ambitions for a clean-sheet design delivering 20 to 30 percent improvements in fuel efficiency compared to current aircraft, with full compatibility for sustainable aviation fuels.
Engine selection for this program is expected around 2027, with a formal program launch potentially occurring near the turn of the decade. The data gathered from COMPANION’s flight-test campaigns will prove instrumental in that decision-making process.
CFM’s RISE technology faces competition from Rolls-Royce, which is developing a narrowbody-sized variant of its UltraFan geared turbofan demonstrator. While the British manufacturer has opted for a conventional ducted architecture, it’s targeting similarly ambitious efficiency gains. Clean Aviation’s latest funding round includes provisions for ground testing of this alternative concept alongside the open-fan flight demonstrations.
The parallel development tracks reflect the magnitude of the challenge facing engine manufacturers. Neither CFM nor Rolls-Royce can afford to fall behind in the race to power whatever aircraft Airbus and Boeing ultimately bring to market. And for Airbus, maintaining the dual-source engine supply model that has served the A320 family so well requires viable alternatives from multiple suppliers.
As MSN114 undergoes its remarkable transformation from retired airliner to experimental platform, it embodies something larger than any single research program. The aircraft represents European aviation’s bet that revolutionary propulsion technologies can deliver the step-change improvements needed to meet climate commitments. Whether open-fan designs will ultimately prevail remains an open question—but the superjumbo that once carried passengers across continents now stands ready to help write the next chapter of aviation history.
