A FreeCAD workbench dedicated to Airplane Design
Warning: This is highly experimental code. Testers are welcome.
v0.4: New Object : Plane, Wing and WingPanel. New Wing generator. Naca Rib generator.
v0.3bis: Nacelle generator by Claude
v0.3: NACA Rib generator
v0.2: New release with parametric objects based on a dedicated UI
v0.1: Initial release based on sheet deprecated!
v0.001: 11 July 2018: Initial version
- FreeCAD >= v0.18 install "Plot" & "Curved shapes" WorkBench.
Use the FreeCAD Addon Manager from the tools menu to install AirPlaneDesign Workbench. You will also require Plot and CurvedShapes addons (both also available in the Addon Manager)
There are various examples available. Under Windows these are in: C:\Users\USERNAME\AppData\Roaming\FreeCAD\Mod\AirPlaneDesign\examples
To create your own from scratch: After installation a new Airplane Design menu and toolbar will be available You must first "Create a plane" (you can give it dimensions but it won't be visible) Ensure the plane is selected in the navigation window and select "Create/Add a wing to plane" Ensure the wing is selected in the navigation window and select "Wing Wizard" Click "Fill in Sheet With Example" to create the demo wing
The menu contains with the following functions:
- Create a rib : you can import DAT file or generate NACA Profile. 1.1 Import a DAT File Simply copy the DAT File in the folder
1.2 Create a Rib based on a DAT file
In the menu AiplaneDesign select create a RIB, the dialog below appears, click on the tab "Import DAT File".
Select in the tree the dat file you want to use and define the chord of the rib and clic OK. That's all. You can change directly in the GUI of the object the Dat File, the chord (in mm).
1.3 Use the NACA Generator You can generate Naca profil 4 or 5 digits. In the menu AiplaneDesign select create a RIB, the dialog below appears, click on the tab "NACA Generator". Simply fill the NACA Number, the number of points you want to generate and the chord in mm. A preview is automatically generated.

V0.5 : Some ideas....
- Generate Rib from Wing
- Xfoil integration

- Add option to Automatically generate a mirror wing for the other side
- Wing wizard remembers settings from previous wing
- Copy and paste the wing wizard table (eg to and from a spreadsheet)
