These wings fasten on the bottom of flying cars, maglev-trains or airplanes.
They create additional elevating force and ground effect.
For avoidance of non-uniformity of pressure, the wings have different parameters. Their area grows in process of removal from a bumper.
I.e. the second wing is more than the first, the third wing is more than the second, etc.
Thus under magnetic train the uniform air-cushion is created.
And in case of the flying car the balance between a forward and back part of a fuselage is kept..
