A sharkskin-inspired material is taking flight, and it could reshape the future of aviation. Developed by Australian firm MicroTau, the coating mimics the microscopic grooves found on a shark’s skin. When applied to an aircraft’s surface, the material reduces air resistance, cutting fuel use and carbon emissions. Early tests suggest it could boost fuel efficiency by up to 4%, potentially saving the industry as much as $10 billion annually.
Boom Supersonic recently trialled the “riblet skin” on its XB-1 demonstrator, applying it to the jet’s underbelly. The sleek material survived both subsonic and supersonic flights, proving durable under extreme conditions. These tests were conducted with support from the U.S. Defense Innovation Unit and the Air Force Operational Energy Office.
Military and commercial use cases expanding
The U.S. Air Force is now eyeing the technology for its fuel-hungry cargo aircraft. Models such as the C-17 Globemaster III, C-130 Hercules, and KC-135 Stratotanker may soon be upgraded with this high-efficiency skin. These massive planes are notorious for their enormous fuel demands; improvements here could translate to immense cost and emission savings.
MicroTau says the riblet film can be added to wings, tails, and fuselages without affecting aircraft weight. Its adhesive strength was a key focus during initial XB-1 flights, and results have been promising. CEO Henry Bilinsky emphasized its dual benefit: “Commercial aviation can expect a profit uplift of around 20% from fuel cost savings alone.”
Commercial airlines are also exploring the innovation. Delta Air Lines is testing the material on its Boeing 767 fleet, while Lufthansa has already equipped cargo jets with a similar AeroSHARK coating from BAF. Other carriers; Japan Airlines and Swissair, have joined the early adoption wave, using riblet tech to reduce operational costs and environmental impact.
