9.6: Input Angle for Geometric Twist

Especially with flying wing constructions it is necessary to twist a wing in order to constrain a definite lift distribution.
Click the folder button 'Geometric Twist'. The wash angle will be displayed in the input field 'Wash Angle [°]'.
Valid values lie between -45° and +45°.
The wash angles centre of rotation lies at the leading edge.
Near the input field are Up/Down-buttons located. They can be used to change the wash angle with mouse clicks.
A click on the right mouse button pops up a menu to set the increment between 0.00001° and 1°.



The following picture shows three wings. The left wing has no geometric twist, with the middle wing both segments have -30° geometric twist and with the right wing a geometric twist of +30° is implemented.
The shown angles are strongly exaggerated, normally geometric twist angles range between 2° and 10°.
