Lufthansa applies aerodynamic sharkskin film on aircraft

Lufthansa Technik and BASF have jointly developed the functional surface film AeroSHARK for commercial aircraft. The film is modelled on the microscopic structure of shark skin and is applied to the aircraft's outer skin. It directly reduces aircraft drag, cuts kerosene consumption and thus CO₂ emissions. The Lufthansa Group will be the first airline group in the world to equip more than 20 long-haul aircraft in its fleet with aerodynamic sharkskin film. Following extensive testing and a certification process lasting several months, the EASA has now granted Lufthansa Technik a Supplemental Type Certificate (STC) for the series application of this technology on two Boeing 777 models. In the future, all twelve long-haul B777-300ER aircraft at SWISS will fly with the fuel-saving surface technology. The same applies to Lufthansa Cargo's current fleet of eleven Boeing 777F freighters. The first SWISS aircraft equipped with AeroSHARK (registration HB-JNH) has already been in scheduled service since October. This aircraft had also completed the flight test program for the certification it has now received. In January 2023, the next Boeing 777 aircraft in Frankfurt and Zurich are scheduled to be modified with the riblet films.<br/>
