8.8: Input Angle of Incident

To obtain the desired aerodynamic characteristics for multi-wing airplanes it is often necessary to install the wings with definite angles of incident. Therefore the wing will be installed in an angle against the X-axis.
Click the folder button 'Angle'.

Into input field 'Angle of Incident [°]' you can enter the angle of incident for the active wing.

The dimensional unit for entered data is 'degree' [°].
Valid values lie between -90° and +90°.



Near the input field are Up/Down-buttons located. They can be used to change the wings angle of incident with mouse clicks.
A click on the right mouse button pops up a menu to set the increment between 0.00001° and 1°.

In the following picture you can see two wings. The black line is the X-axis of the airplane.
The left wing is installed with a +20° angle of incident while the right one is installed with a -20° angle of incident.
The reference point for twist is the wing zero-point (middle of leading edge).
