From the sea to the air, shark skin inspires Lufthansa to seek greater fuel savings and reductionón CO emissions2 on their planes. Prensa Lufthansa's photo.
The lower the resistance to frictionón of a grandfatherón in the air, lesser beingá the consumption of combustible. Using the nature as a role model, the aviation industryón has been intensively researching ways to reduce aerodynamic drag.ámica for many toños.
Now, Lufthansa Technik and BASF have achieved a breakthrough as part of a joint project. AeroSHARK, one skinísurface film that imitates the fine structure of shark skin, will unfoldá throughout the fleet of freighters Lufthansa Cargo since the beginning of 2022, what will doá that the aircraft is más económica and reduce your emissions.
The surface structure consisting of riblets measuring about 50 micrómeters imitates the properties of shark skinóno and, Thus, optimizes aerodynamicsámica in the parts of the aircraft related to air flow.
This means less fuel is needed overall. for freighters Boeing 777F by Lufthansa Cargo, Lufthansa Technik estimates a reductionón of aerodynamic dragábit of más of one percent. For the entire fleet of ten aircraft, This translates into annual savings of around 3.700 tons of kerosene and just under 11.700 tons of CO2 emissions, equivalent to 48 individual cargo flights from Frankfurt to Shanghai.
In your cooperationón with BASF, Lufthansa Technik is responsible for the specificationómaterial no., you approveón by aviation authoritiesón y la implementationón of aircraft modifications carried out as part of regular maintenance calls. Backed by dédrops of experience as an organizationón approved designñthe aviationón, the compañíto getá a Supplemental Type Certificate (STC) for the 777F of the Security Agency AéUni areaón European (EASA), what is required to operate.
I divided itón Coatings from BASF isá developing filmíinnovative and functional lines in your Beyond Paint Solutions unit, like the surfaces of riblets, for instance. Se implementó a solutionón together with Lufthansa Technik that meets the strict requirements of the aviation industryón.
Exterior surfaces used in aviationón isán exposed to factors such as strong radiationón ultraviolet, así such as fluctuations in temperature and pressureón and high altitudes, among others. Therefore, BASF has focused its development on achieving extreme durability and weather resistance. Key criteria for use in aviation operationsóThey do not include an applicationóSimple n and operation, así such as ease of repairón, for which a personalized concept has been developed.
Andún sleepón has been hurt for the development of this technological advanceógic.
