The wing is the main load-bearing surface on which most of the buoyancy is generated during movement. Since all aircraft are heavier than air, the wings are an essential part of the aircraft. It depends on their arrangement, shape, profile and design. The wing of an airplane has a certain cross-sectional shape, the profile, over its entire span. We speak of wings primarily in aircraft, but similar principles apply to helicopter rotors, propellers, or turbine blades.
Buoyancy on a wing is generated as a force reaction to wrapping, which can be visualized by streamlines - the moving wing deflects the surrounding medium so that it is forced to wrap around it at different speeds. At the higher velocity points, a vacuum is created on the opposite surface to the opposite surface causing a difference in pressure forces on the wing as a reaction, with the aircraft facing upwards. At the leading edge of the wing, the air separates and at the trailing edge the streamlines merge. The airfoil must be designed so that no unnecessary vortices are created during the wrap-around process, as energy is wasted on their formation. The junction of the extreme points of the profile (at the leading and trailing edges) is called the profile chord. The airfoil chord makes an angle of attack with the longitudinal axis of the aircraft, which contributes significantly to the lift generation, effectively changing the wrap-around function of the airfoil.
Wings can be straight, that is, perpendicular to the aircraft axis, or swept, which is advantageous for higher speeds. For supersonic speeds, a delta wing is used, or variable wing geometry is used, where the wing sweep (the angle between the leading edges of the two wing halves) can be varied as required in flight. This shifts the aerodynamic centre of gravity of the wing, thus changing the wrap-around profile (aerodynamic slimming). At the same time, for supersonic aircraft, the wing is largely out of the shock wave.
