mean chord

mean chord
i. The chord of an imaginary wing of a constant section having the same force vectors under all conditions as those of the actual wing. That chord of an airfoil is equal to the sum of all the airfoil’s chord lengths divided by the number of chord lengths. Equivalently, it is that chord whose length is equal to the area of the airfoil section divided by the span.
The mean geometric chord location is the same for two extreme positions of the root chord.
ii. Sometimes wrongly referred to as a mean aerodynamic chord.
The mean geometric chord location is the same for two extreme positions of the root chord.
