A new relation between the induced yawing moment and the rolling moment of an airfoil in straight motion (1925)
NASA Technical Reports Server (NTRS) · leaf 5
. COMPARISON WITH EXPERIENCE I found only one series of tests (reference 2) suitable for checking the formula obtained. That report contains a diagram with the'coefficient of yawing moment plotted against the coefficient of rolling moment. Both coefficients are obtained by dividing the moments by… … -ao8 -ao6 -ao4 -aoe o Rolling moment coefficient (KL) A glance at this diagram makes it at once apparent that the type of relation suggested by the theory has actually been observed by these tests. The individual curves for particular angles of attack are. substantially straight lines, passing…
