Lufthansa Technik and chemical company BASF have developed an innovative aerodynamic film called AeroSHARK, inspired by the microscopic structures found on shark skin. The technology is designed to reduce aerodynamic drag and improve aircraft fuel efficiency.
The transparent polymer film features millions of tiny riblets, approximately 50 micrometres high, which help reduce skin-friction drag by influencing airflow across the aircraft’s surface.
Swiss International Air Lines and Lufthansa Cargo have applied the technology to Boeing 777 aircraft, covering approximately 950 square metres across the fuselage and engine nacelles. According to the companies, the modification can reduce aerodynamic skin-friction drag by more than 1%.
The technology can help airlines reduce fuel consumption and carbon emissions during long-haul operations. Reported estimates suggest savings of around 400 tonnes of kerosene and 1,200 tonnes of CO₂ per aircraft annually.
AeroSHARK demonstrates how biomimicry, or technology inspired by nature, can contribute to more efficient and sustainable aviation.
