Ribs drawing

Ribs interpolation for a trapezoidal or elliptical wing plan

By only one  dialog window you can generate all the ribs for a trapezoidal or elliptical wing plan, with different airfoil profiles at root and tips.
You can also add leading and trailing edges and spars (and now also new types of spars) and also rounded lightening holes. Profili will generate a new document for every rib. 

Here is an example:

 

The same document can be drawn, printed and exported in DXF also as a different type, simply by clicking on the toolbar buttons.
For example you can have the real shape of the ribs you are going to cut:

or the templates to check the leading edge:

The ribs can also be created one by one by the Airfoils database dialog window. All the added rib components can be then modified by the buttons on the toolbar.

If your printer can manage only paper format with a smaller size than the airfoil you need, the printout will be split in two parts. Profili will also draw marks to join the pieces in the right way:



The rib can then be exported in DXF format so that you can import it in a CAD or CAD-CAM application.
