      - Click the '​Driver:'​ pulldown and select '​Span-TC-RC'​ as the driver group. ​ This will activate span, tip chord, and root chord as the independent variables. ​ Aspect ratio, taper ratio, and area will be calculated to agree. \\ {{:​10_change_driver.png?​direct&​200|}}      - Click the '​Driver:'​ pulldown and select '​Span-TC-RC'​ as the driver group. ​ This will activate span, tip chord, and root chord as the independent variables. ​ Aspect ratio, taper ratio, and area will be calculated to agree. \\ {{:​10_change_driver.png?​direct&​200|}}

-     * Note that the aspect ratio is now 1.9004 (instead of 1.9) and the taper ratio is now 0.5622 (instead of 0.562). ​ Increasing the tip chord will drive aspect ratio closer to the target value - but will also drive taper ratio further from the target value.+     * Note that the aspect ratio is now 1.9004 (instead of 1.9) and the taper ratio is now 0.5622 (instead of 0.562). ​ Increasing the tip chord will drive aspect ratio closer to the target value - but will also drive taper ratio further from the target value.  The parameter values match the published values - within the published significant figures.

      * As described above, the Onera M6 uses the Onera D section orthogonal to the 40.18% chord line.  This section has been transformed into a streamwise airfoil and put into VSP airfoil format.      * As described above, the Onera M6 uses the Onera D section orthogonal to the 40.18% chord line.  This section has been transformed into a streamwise airfoil and put into VSP airfoil format.
