Aviation Innovations Inspired by Nature’s Designs
The natural world has long been a powerful source of inspiration for technological advancements, particularly in aviation. Humans, fascinated by the extraordinary abilities of animals and insects, have looked to nature to solve complex engineering challenges. From the mythical Icarus story to modern-day biomimicry, nature continues to shape the future of flight.
One of the most significant ways aviation has advanced through nature-inspired design is in the realm of biomimicry research. The study of nature’s structures has led to groundbreaking innovations in aircraft technology, improving efficiency, reducing fuel consumption, and enhancing overall performance.
AeroSHARK: Shark Skin Inspires Fuel-Efficient Technology
In October 2024, SWISS became the first airline to fly a Boeing 777-300ER equipped with AeroSHARK, a bionic surface film inspired by the microscopic structure of shark skin. Developed by Lufthansa Technik and BASF, the film mimics the unique texture of shark skin to optimize airflow over the aircraft’s fuselage and engine nacelles. Each AeroSHARK patch is covered in millions of tiny, 50-micrometer-high riblets that reduce friction, leading to significant efficiency gains.
This innovation marks a milestone in aviation sustainability. The first freighter to be modified with AeroSHARK was a Lufthansa Cargo Boeing 777F in December 2023. Later that year, LATAM Airlines Brasil became the first carrier in the Americas to adopt the technology on a Boeing 777. With SWISS now equipping its entire Boeing 777-300ER fleet with this technology, AeroSHARK is expected to reduce fuel consumption and enhance aircraft performance.
Winglets and Sharklets: Bird-Inspired Flight Efficiency
Another major leap in aviation technology came from the study of birds’ wing structures. In the 1970s, NASA-funded engineer Richard Whitcombe discovered that birds curl their wingtip feathers upward during flight to gain greater lift. This observation led to the development of wingtip devices, which reduce drag and increase fuel efficiency.
Boeing introduced its first wingtip device on the Boeing 747-400 in 1988, later evolving the design into blended winglets. Airbus followed suit, launching its Sharklets in 2012 for the A320 family. These devices have since become standard on modern aircraft, reducing drag and improving fuel efficiency by 6-7%.
Fello’fly and the Snow Geese
Airbus has become a leader in biomimicry research, exploring how natural principles can improve aircraft design. One of its projects, fello’fly, is inspired by the flight patterns of Snow Geese. These birds adopt a “V” formation during long-haul flights to conserve energy, allowing them to travel vast distances with minimal fatigue.
Airbus replicated this behavior by conducting formation flight demonstrations with two A350 aircraft in 2021. The test flight from Toulouse to Montreal saved more than six tons of CO2 emissions, proving that aircraft flying in formation can reduce fuel consumption by over 5% on long-haul flights.
AlbatrossONE: The Bird with the Ultimate Wingspan
In 2019, Airbus unveiled the AlbatrossONE project, inspired by the albatross, a bird known for its expansive wingspan and ability to navigate long distances using minimal energy. The project explored the potential for semi-aeroelastic wing tips, which could improve aircraft performance by reducing wing loads.
In 2020, Airbus tested a demonstrator with wings 75% longer than previous models, showing positive results in improving aerodynamic efficiency. This research continued under Airbus UpNext, a subsidiary focused on developing wings that can change shape during flight, further advancing the potential of biomimicry in aviation.
From shark-inspired surfaces to bird-shaped wing tips, nature continues to guide innovation in aviation. These biomimicry breakthroughs are not only improving aircraft performance but also contributing to more sustainable, fuel-efficient air travel.
