Aircraft operate on the basis of aerodynamics. During the movement, the air passes above and below the wings of the aircraft. The wings in the plane are flat on the bottom and rounded at the top. By bending the wing on both sides, the air is separated - air above the rounded surface of the wing passes faster than under the flat lower part. The air from the top is diluted, the pressure becomes less than the air at the bottom of the wing, and thanks to this the wing tends to rise upward. Thus, the uneven air pressure resulting from the shape of the aircraft's wings generates a force called a matrix. Thanks to this power the aircraft can fly.
