This new design mimics the movement of the hummingbird's wings, which stands out for its speed and efficiency in flight. The hummingbird can flap its wings 55 to 75 times per second, a technique that allows it to stay aloft using less energy.
Until recently, scientists had been limited in their ability to translate movement from animals and humans to machines, according to Tyer Wind. In the wind energy sector, this limitation has resulted in relatively inefficient and simple turbines. They use a new technology called 3D Aouinian kinematics, which greatly reduces the size of the blades and drastically reduces the noise they generate.
It has two vertical axis carbon fiber wings measuring 1.60 m each. They take up less space than conventional ones but they also generate less energy, 1 kW.
Hassine Labaied, partner and co-founder of Tyer Wind, says it is the first time that a mechanical device has successfully mimicked the movement of a Hummingbird.
In the video we can see a prototype that is currently being tested in Tunisia. They assure that their initial tests in terms of energy efficiency, aerodynamic behavior and resistance of the material are encouraging.
At the moment we do not know their manufacturing plans, nor their possible price.
