Goland Wing Examples
====================

The function `gen_goland_wing.m` is installed with the BAFF toolbox, and can be used to generate a baff model of the *Goland wing*.

The Goland Wing is a classic test case for aeroelastic analysis. It is a simple cantilevered wing with a rectangular planform and a NACA 0012 airfoil. The wing is clamped at the root and free to deform in the vertical direction.

The primary properties of the Goland wing are:

+------------+--------+-------------------------------------------------+
| Property   | Value  | Note                                            |
+============+========+=================================================+
| Span [m]   | 6.096  | 20ft span                                       |
+------------+--------+-------------------------------------------------+
| Chord [m]  | 1.8288 | 6ft chord                                       |
+------------+--------+-------------------------------------------------+
| EI [Nm^2]  | 9.77e6 | bending rigidity                                |
+------------+--------+-------------------------------------------------+
| GJ [Nm^2]  | 0.99e6 | torsional rigidity                              |
+------------+--------+-------------------------------------------------+
| \mu [kg/m] | 35.71  | linear density                                  |
+------------+--------+-------------------------------------------------+
| x_m [%]    | 43%    | location of center of Mass (% of chord from LE) |
+------------+--------+-------------------------------------------------+
| x_f [%]    | 33%    | location of elastic axis (% of chord from LE)   |
+------------+--------+-------------------------------------------------+
| I_x [kg.m] | 8.64   |  moment of inertia about elastic axis           |
+------------+--------+-------------------------------------------------+

Most of these values can be easily changed in the `gen_goland_wing.m` function; however, the Goland wing is generated by calling the function with no arguments.
