<p>This architectural drawing is Airplane design in detail AutoCAD 2D drawing, dwg file, CAD file. The design of an airplane wing is intended to speed up airflow across the top of the wing. Air pressure decreases when it moves more quickly. Therefore, the pressure at the top of the wing is lower than that at the bottom. The pressure differential exerts a force on the wing, lifting it into the air. For more details and information download the drawing file.</p>
