Researchers have developed a wing of a plane that changes shape



In the journal "Smart materials and structures" the research team explains how it radically changed the wing of the aircraft. Their new structure is a lightweight grid, consisting of thousands of repetitive tiny triangles, similar to similar racks covered with a thin polymeric layer. Since this "metamaterial" consists mainly of empty space, it is extremely lightweight ̵

1; less than one thousandth of the density of rubber. And, carefully arranged racks allow the wings to change the shape automatically in response to changes in aerodynamic loading conditions. Both factors can make the plane more energy efficient

This is not a completely new concept. It was introduced several years ago, but now researchers have developed a way of making individual parts for the wing with the help of injection molding. They brought the time needed to make each part – an empty cube with tiny racks around each edge – from a few minutes to 17 seconds. While the model that they created was manually assembled, the process was designed to be repetitive, so that in the future, small stand-alone works will be able to collect the wings. -the movement of the wing raises the question of the ideal shape of the plane. With this technology, we could be able to break away from the "pipe with wings" design and use a more efficient configuration – perhaps a built-in body and wing structure. If the idea of ​​watching a change in the shape of the wing of an airplane during a cruise of thirty thousand feet, do not worry. This is a long way from a commercial ready-made airline. Meanwhile, it also has the potential for the reconstruction of other structures, such as wing-like blades of wind turbines.
