Center Of Pressure Impact Factor

A point on a plane surface where the resulting force passes through due to pressure. If no other forces act, such a surface may be supported by a single mounting fixture at its center of pressure. For example, at its center of pressure a water gate in a dam can be supported by one single shaft. The pressure center does not remain in a constant position. As the angle of attack changes, so does the local pressure on the aerofoil at every point. This, in effect, is causing a shift in the center of pressure position.
