Saint Petersburg scientists developed «feathers» for plane to cope with turbulence

Researchers from the Saint Petersburg State University have developed controlled mechanisms for airplane wings, the so-called «feathers» capable of adjusting to the wind and compensate for turbulence.

«We have designed „feathers“ for airplane wings which are driven mechanisms supported by the pressure sensors which can rise upward and rotate using an electric motor and by doing so compensate for turbulence. To control the system of „feathers,“ there is no need for a central computer, but the devices are connected to the network and can tune to each other. Each time a „feather“ adjusts to the neighborhood „feathers.“ If the pressure on the next parts is slightly higher, a „feather“ rise itself a little. Otherwise, it lowers a bit. As a result, joint processes are going on all wing elements, and we can adjust to every wind current,» - Doctor of Physical and Mathematical Sciences, Professor at SPbSU Oleg Granichin explained.

The researchers have already tested the prototype of «feather» system using an unmanned flying vehicle, with the wingspan being 2 meters. Now, they are maintaining the next more perfect variant of the development. The test flights are scheduled as a next step.

«There is nothing in excess in nature. If birds fly in the air using feathers but not as bald creatures, this means that such flights are more beneficial from the viewpoint of aerodynamics,» - the researcher noted. Professor Granichin also commented that the development would be additionally adapted to be used in underwater devices.
