WebAug 25, 2024 · The line called “spanwise component” or “spanwise” is neither the one, nor the other. The spanwise component of the airflow would be a line drawn perpendicular to a chord line, between the extension of that line behind the trailing edge and the point where the airflow that hits that chordline at the leading edge leaves the trailing edge.
