FLEXIBLE WINGS PROFILE new wing profile that can deform in contrast to classic profiles and thus achieves better buoyancy properties, and reduces air resistance.

摘要

The wing profile makes better use of dynamic flow properties than classically rigid profiles by having a dynamically deformable contour. The present invention is concerned with a wing profile that can dynamically adapt itself to the flow conditions by deforming of the profile. Its advantage is that, by contrast with classically rigid wing profiles or wing profiles provided with flaps, it can under often rapidly changing flow conditions, such as for example in cases of turbulence, adapt itself individually and flexibly in the profile contour. A viscous medium has the property that under certain preconditions it itself forms the ideal flow body. This profile makes use of this property. This improves as a result the lift characteristics and consequently also increases the immunity from flow separation, in particular during landing manoeuvres. The consequently reduced turbulences also ultimately allow a lower flow resistance to be achieved. The profile at the same time generally dispenses with active control of the deformation and instead uses the property of the flow encountered that it tends itself to prescribe the ideal aerodynamic form of the profile. This function is explained in detail hereafter.
