It could usher in a new generation of more efficient and sustainable aircraft that promise to take to the skies. But besides being a cutting-edge scientific breakthrough, the new prototype developed by Airbus is an example of biomimetics. In this case, they mimic the wing adaptability of birds in flight.New wing named Extra Performance Wing combat the effects of turbulence.
In this article you will learn:
What is biomimetics
First of all, a little reminder in case you haven’t seen the article with the biomimetics example yet. Basically, biomimetics or biomimicry are Development of technologies and technologies based on the principles and structures of natureThere are three basic biomimetic approaches to replication.
- shape and structure
- process
- Ecosystem
one Velcro is an example of biomimetics that mimic shape and structure., invented by a Swiss engineer in 1941 after a walk in the countryside. George de Mestral noticed burdock seeds on his clothes and his dog’s fur. Upon closer inspection, he found that it incorporated a series of hooks that attached to any surface with loops.
airplane bird wing
In 2019, Airbus conducted test flights with a very specific size aircraft. It was called AlbatrossOne and, as its name suggests, its flight mimicked an albatross. i.e. Its wingtips could move independently like these birds, with a wingspan of up to 12 feet. AlbatrossOne’s wings have semi-elastic hinges that move during strong wind gusts, reducing wing loads and eliminating the need for structural reinforcement. The eXtra Wing Performance project is now continuing with another scale aircraft. Another example of biomimetics.
This system is the next step in implementing biomimetic technology, to be tested in the wind tunnel for its subsequent transition to civil aviation. A scaled-down version of a Cessna with wind sensors, movable flaps and multiple functions. trailing edgeBy changing the shape of the wings and the position of the wings, the developers liken these moving parts to how an eagle soars.In short, this is the evolution to adaptive wings more sustainable aviation.
European manufacturers have shown that these technologies can be implemented in existing aircraft models without the need to modify the propulsion system. Increased efficiency translates into lower costs and lower greenhouse gas emissions. This strategy is also consistent with our commitment to environmentally friendly hydrogen-powered aircraft, as detailed in this article.
Other examples of biomimetics
The transportation industry is a field rich in biomimetic examples, as the eXtra Wing Performance project shows. After all, the movement of animals and insects is one of the most basic aspects. Here are some examples of this type of technology in various fields, from construction to fashion.
- The Oxford, England-based company is developing a series of drones inspired by different animals.For example they A glider drone that follows the flight pattern of a stork.
- Fern Inspired new technology to help clean up oil spills at sea.
- geckoespecially its ability to adhere to virtually any surface, is a source of inspiration for innovative adhesives. slug It also influenced adhesives for medical purposes.
- sunflower It can inspire new sustainable building solutions, like this groundbreaking home designed by a Japanese architect with solar panels that follow the movement of the sun.
- The construction also pays attention to nature with pressure-hardening cement like crustaceans. Mantis shrimp.
- It may not be useful for everyday life, but the ‘biomimimic’ dress designed from recycled salt and plastic is Simulate flowers and transform them in real time, This is one of the most striking examples of biomimicry we have witnessed in recent times.
In addition to the examples above, we have published an article on biomimetic techniques to improve energy efficiency. Are there other examples of biomimetics that caught your attention? Let us know about them in the comments.
