Q: Center of pressure, center of gravity, aerodynamic center, aerodynamic mean chordA: anyone? pls post answer on commentalvin
centre of pressure: is represented as a single point acting on the wing chord line at a right angle to the relative airflow, through which the wing's lifting force is produced. The position of the center of pressure is not a fixed point but depends on the distribution of pressure along the chord, which itself depends on the angle of attack. Thus, for a greater angle of attack, the point of highest suction (highest air pressure value) moves forward the leading edge. The distribution of pressure and center of pressure point thus will be further forward the higher the angle of attack and further aft the lower the angle of attack.
center of gravity: C of G, CG, is the point through which the total weight of the body will act.
aerodynamic center = ?
aerofoil chord line : the chord line is a straight line from the leading edge to the trailing edge of an aerofoil.
mean chord line : is the wing area divided by the wing span (sometimes refered to as the standard mean chord).

aerodynamic center is a point where center of pressure act about that point creating constant moment regardless of AOA. chim? AKA fulkrum point la haha
