Vueling<\/a> and MicroTau announced on May 23, 2025, that the IAG-owned airline would become the first European airline to test the tech firm\u2019s shark skin product on its aircraft.\u00a0\u00a0<\/p>\nUnder the partnership agreement, Vueling will help MicroTau to certify its Riblet Modification Package product so that it can eventually be used on its narrow-body fleet.\u00a0<\/p>\n
MicroTau\u2019s Riblet Modification Package consists of an innovative film that mimics the microscopic texture of shark skin. It is applied to the exterior of the body of aircraft to improve aerodynamic performance, which could reduce carbon emissions by up to 4%.\u00a0<\/p>\n
Although a shark\u2019s skin appears smooth, it\u2019s actually covered in microscopic grooves known as riblets, which help reduce drag as the animal moves through the water.\u00a0<\/p>\n
Using the same principles and applying them to the outside of an aircraft reduces drag without requiring any structural modifications.\u00a0<\/p>\n\n
Franc Sanmart\u00ed, Director of Sustainability at Vueling, said: \u201cThe possibility of implementing MicroTau\u2019s cutting-edge technology across our aircraft once it is certified will mark an important milestone in Vueling\u2019s journey toward sustainable aviation. This innovation not only supports our goal of improving fuel efficiency but also reinforces our commitment to reducing our CO2 emissions through forward-thinking solutions.\u201d\u00a0\u00a0<\/p>\n
