Detail Example Wing_CAD_Example_1



1. Select the NEW button in the Design ListDesign_List Tab

2. Enter or select the appropriate data in the ADD WING SCREENADD_WING_SCREEN. 

3. Click on the ADD button in the ADD WING SCREENADD_WING_SCREEN. 

4. The WING CAD SCREEN WING_CAD will appear.

5. Input the full SPAN of the wing or tail in the SPAN box.

6. Click on the button to turn off rib redrawing.

7. Click on the button to start adding wing coordinates using the mouse.

8. Move the mouse pointer over the wing window and click with the left mouse button when the 

   selected position has been achieved for a leading edge coordinate.

9. Move the mouse pointer down to add the trailing edge coordinate. Click with the left mouse button 

       again. Remember if you wish to undo or cancel these operations , click on the right mouse button.

10. Continue to repeat steps 8 & 9 until all the necessary points have been added to define the

       wing or tail shape.

11. Click on the button to accept the changes and redraw the wing or tail.

12. Enter the required number of ribs per wing half in the RIB NO. box.  Click on the 

      button to redraw the wing or tail.

13. Click on the  button to perform area, aspect ratio and mac calculations.


Remember; at any time you wish to scroll or enlarge or decrease the size of the plot , either move the horizontal and vertical scroll bars either side of the wing window or click on the  button to enlarge

the plot or the   button to reduce the size of the plot.



Steps to modify an existing design using a mouse;


1. Position the plot and scale such that the points which need to be modified can clearly be seen.

2. Click on the  button to identify a coordinate pair.

3. Move the mouse pointer over the wing window and click with the left mouse button near the coordinate pair you wish to modify.

4. A grey rectangle will appear framing the coordinate pair.

5. To move the coordinate pair , position the mouse pointer within the frame. Whilst holding the left mouse button down, drag the frame to the desired position, then let go of the left mouse button . This action will shift the position of the wing coordinate pair.

6. To move one of the coordinates belonging to the pair (you may only shift the coordinate up or down)

click on the grey  HANDLEHANDLE and drag it up or down to the desired position. 

Either of the above actions will automatically save the changes. 

To undo the change, click on the button.


To move the entire wing or tail ;

1. Position the plot and scale such that the wing or tail root is visible. (Rib 1)

2. Click on the  button to identify a coordinate pair.

3. Move the mouse pointer over the wing window and click with the left mouse button near the wing or tail root (Rib 1).

4. A grey rectangle will appear framing the coordinate pair.

5. Position the mouse pointer within the frame. Whilst holding the left mouse button down, drag the frame to the desired position, then let go of the left mouse button . This action will shift the position of the entire wing or tail.
