Lufthansa Technik has entered the final phase of supplemental type certification for its AeroSHARK surface technology on the Airbus A330-200 and A330-300, marking an important step in bringing the drag-reduction solution to Airbus-operated fleets.
A Discover Airlines A330 long-haul aircraft is currently undergoing several weeks of test flights before and after modification at Elbe Flugzeugwerke GmbH (EFW) in Dresden. Once certification is complete, the aircraft is expected to become the first Airbus aircraft worldwide to be equipped with AeroSHARK.
The European Union Aviation Safety Agency (EASA) is conducting the certification programme, supported by Mastercard through its strategic partnership with the Lufthansa Group.
Expanding AeroSHARK to the A330 Fleet
The A330 represents an important target for AeroSHARK because of its large installed base and continued role in long-haul operations.
According to Lufthansa Technik, the A330 is the second-most-delivered long-haul aircraft family globally and is expected to remain an important part of airline fleets for many years. Certification of the technology for the A330-200 and A330-300 would therefore significantly expand the number of aircraft that could potentially benefit from the technology.
For the MRO industry, the development also demonstrates how aerodynamic efficiency technologies can be introduced into existing aircraft fleets through modification and certification rather than relying solely on new aircraft deliveries.
Biomimetic technology inspired by Shark Skin
AeroSHARK has been jointly developed by Lufthansa Technik and Surventis. The technology replicates the microscopic riblet structure of shark skin on an aircraft’s exterior surface. The surface structure is designed to reduce aerodynamic drag, which can lower fuel consumption and associated carbon emissions during flight.
The technology is already certified for several Boeing 777 variants, including the 777F, 777-300ER and 777-200ER. Lufthansa Technik said AeroSHARK-equipped aircraft have accumulated more than 400,000 flight hours, delivered reported fuel savings of more than 23,000 tonnes and reduced CO₂ emissions by more than 75,000 tonnes.
Discover Airlines aircraft undergoing testing
The Discover Airlines A330 is currently being used as the test aircraft for the certification programme at EFW’s Dresden facility.
The aircraft is undergoing test flights before and after modification to enable the certification team to assess the technology and its impact on aircraft performance.
The use of an operating airline aircraft in the programme also highlights the role of MRO and modification facilities in introducing new efficiency technologies into existing fleets.
Once certification is achieved, AeroSHARK could potentially be deployed on additional A330 aircraft, creating new opportunities for MRO providers involved in aircraft modification, installation, inspection and associated maintenance activities.
Next-gen AeroSHARK in development
Lufthansa Technik is also working on the next generation of AeroSHARK technology. The new material is being developed for application to additional aircraft surfaces, including wings and tail sections. According to the company, expanding the technology beyond its current applications could potentially double the fuel and emissions savings.
The development points towards a broader role for aerodynamic surface technologies within aircraft retrofit programmes, particularly as airlines look for ways to improve the efficiency of existing fleets while extending their operational lives.
A new opportunity for widebody retrofitting
The A330 certification programme represents more than the introduction of a new aerodynamic technology to another aircraft type. It highlights the growing importance of retrofit solutions that can improve the environmental and operational performance of aircraft already in service.
As airlines continue to operate older-generation widebody aircraft alongside newer models, technologies such as AeroSHARK could provide another pathway to reduce fuel consumption without replacing the aircraft itself.
The completion of the EASA certification process will therefore be closely watched by airlines, lessors and MRO providers, particularly as the global A330 fleet continues to support long-haul passenger and freighter operations.
With the Discover Airlines aircraft now progressing through flight testing, AeroSHARK is moving closer to becoming an Airbus A330-certified modification, potentially opening a much larger market for biomimetic aerodynamic technology across the global aftermarket.
