The faux-sharkskin, called AeroSHARK, was already being used on over a dozen aircraft owned by Lufthansa and its subsidiary airlines, which have collectively flown over 100,000 hours while outfitted with the scaly material, [according to the airline](). And now, off the back of promising results, Lufthansa says it will be adding the sharkskin, in the form of extremely thin riblets, to another four Boeing 777-200ER airplanes operated by Austrian Airlines, [*Ars Technica* reports]() — which could signal even more widespread use in the future. ## Skin in the Game Sharkskin is well known for being abrasive. If you rub your skin against it the wrong way, it'd burn you like sandpaper, due to tiny V-shaped scales called dermal denticles that comprise its surface. This same property, however, is also what makes sharkskin so efficient for swimming. In addition to their shape, the denticles also benefit from their uniform orientation towards the shark's rear, which makes forward movement far slicker. The drag-reducing properties of sharkskin have prompted experimentation with synthetic materials [for decades](), like in swimsuits — [controversially]() — as well as boats and now aircraft. But there's still [much to be understood]() in our efforts to borrow from these creatures, since a variety of factors like the shape, sizing, and distribution of the denticles can affect how they reduce drag. Any combination of those variables can produce wildly different results, especially when transplanting the effects from sea to air. ## Rough Around the Edges That being said, Lufthsansa's formulation already seems to provide tangible benefits. Four Boeing passenger planes will be covered with about 9,000 square feet of AeroSHARK riblets, which is expected to reduce drag by about one percent. That may not sound like a lot, but even that tiny margin will make a significant difference over many flights. The airline [claims]() that over four years, the aircraft will each save about 8,300 metric tons worth of CO2 emissions — the equivalent of 46 flights from Vienna to New York In addition to the four new aircraft, which won't be fully upgraded until March, Lufthansa has outfitted 17 other airplanes with the sharkskin tech: a dozen Boeing 777-200ERs operated by SWISS, a Lufthansa Boeing 747-400, and the four Lufthansa Cargo 777F aircraft. On its own, slapping sharkskin onto planes won't transform the aviation industry into being carbon neutral, which [major airlines have pledged to achieve by 2050]() — but every little bit helps. **More on aviation:** *[Boeing Contractors Say They Were Treated Like "Cockroaches"]()* ## Author At Futurism, my work has often centered on bringing a sense of clarity and insight to complex topics ranging from the regulation of emerging technologies to the esoteric ideologies of Silicon Valley executives, while striving not to lose the poetic sense of awe inspired by often-obscure fields like astrophysics and quantum computing. I broke the story of CNET using AI to produce articles that turned out to be riddled with factual errors and plagiarism — a dam-breaking inflection point, as I've reported, that's inspired copycats and endless discourse while beguiling stakeholders ranging from tech giants to purveyors of spam around the web. My work at Futurism has been cited by publications including CBS News, the Los Angeles Times, Vice, Gizmodo, Engadget, the Verge, and Vanity Fair. I grew up in locales ranging from India to China, and now live in the exotic suburbs of Virginia. In my free time, I'm an avid reader of weird sci-fi literature, an aficionado of East Asian cinema, and, regrettably, a relapsed gamer. Allegedly, I’m working on a debut novel, currently untitled. ### Author social links [Bluesky]()
