Lufthansa Technik is expanding the use of low-drag aircraft surfaces with 'AeroSHARK' after receiving European Union Aviation Safety Agency approval for use on a Discover Airbus A330-300. That clearance allows the airline to apply the film to another aircraft family to reduce drag and improve fuel burn on long-haul trips.
The polymer layer replicates the ridged texture of shark skin with embossed 50-micrometer grooves, helping keep small vortices off the fuselage so airflow remains steadier. It reduces fuel use and emissions by about 1% per flight, with gains reaching 2% when the film also covers the wings and tail surfaces.
For airlines, this means an efficiency retrofit that does not require a new aircraft design. A surface treatment already in use on Lufthansa Group Boeing 777s can now be applied across a wider long-haul aircraft family, giving carriers another way to pursue operating and emissions cuts on existing jets.

What Makes This Trend Stand Out
- Biomimetic Aircraft Coatings
- Shark-skin-inspired surface films introduce measurable efficiency gains through aerodynamic texture changes that can be retrofitted onto existing aircraft fleets.
- Retrofit Sustainability Upgrades
- Incremental aircraft modifications are creating lower-cost pathways for emissions reduction without requiring full fleet replacement or new airframe designs.
- Fuel-efficient Long-haul Aviation
- Small drag reductions on wide-body aircraft are becoming commercially meaningful as airlines seek operational savings across high-frequency intercontinental routes.
Sectors Adopting This
- Commercial Aviation
- Airlines gain new options for reducing fuel burn and emissions through certified surface technologies applied to in-service aircraft.
- Aerospace Materials
- Advanced polymer films with micro-structured textures are expanding the role of specialty materials in performance-focused aircraft retrofits.
- Aircraft Maintenance
- Maintenance and retrofit providers can capture value by integrating aerodynamic efficiency upgrades into scheduled service programs.
