Ⅰ.INTRO
Aerodynamic force such as lift and drag acts on the aircraft from the moment it rises to landing.
aerodynamic force is an essential element of an aircraft, and these forces have been developed in various shapes to increase and efficiently use these forces. Today, we will look at the aerodynamic force acting on these aircraft and the shape of the wing bone that has changed in various ways.

Ⅱ.BODY
1. Airfoil section
■ Airfoil: A surface designed to obtain a useful reaction from the air through which it moves. Such surfaces as a wing, a propeller blade, vertical and horizontal stabilizers are airfoils.

■ Camber: The rise of the curve of an airfoil section from its chord line.

■ Chord line: A straight line between the extremes of the leading and trailing edges of an airfoil section.

■ Leading edge: The foremost part of the airfoil which first meets the relative wind.

2. Aircraft airfoil types
-NACA 4 Series
NACA 4 series maximum camber the position of the chord length, located behind the 40 percent of the airfoil as used usually very low speed, the aircraft's wing airfoil.
