Webthe first digit specifies the maximum camber (m) in percentage of the chord (airfoil length), the second indicates the position of the maximum camber (p) in tenths of. Webfrom figure 3, it can be seen that the leading edge of the airfoil is the most sensitive to the distribution of roughness, and the effect of roughness on the. Webthe chord is a basic reference axis for the geometric or aerodynamic properties of an airfoil.
