This screen controls the printing of ;
1. Wing Ribs
2. Wing Specifications
3. Wing Planform
You may select to print all or any combination of the above.
This screen also is used to export ribs and wing/tail designs to DXF files for import into CAD programs such as AutoCAD.
Name
This is the name of the currently selected wing.
Type
This is the type of wing. Eg; Vertical Tail, Horizontal Tail or Wing.
Units
Measurement units. Eg; Inches or Millimetres.
Root Airfoil
The airfoil section selected for the wing root.
Tip Airfoil
The airfoil selected for the wing tip.
T/C%
This is the airfoil maximum thickness. You may vary this by entering a new value for the thickness. Winfoil will automatically calculate the new coordinates for the airfoil based on the ratio of the new thickness and the original thickness. To reset the thickness to its original value , click on the Reset button.
A list of the Ribs for the wing is listed on the screen. If there are more ribs than will fit in the grid then you can scroll the grid by moving the vertical scroll bar on the right of the grid.
The Print column of the grid indicates if the rib is to be printed. This is toggled on and off by clicking in the appropriate cell. A tick means print, a cross means do not print.
There are three buttons immediately below the grid.
Print All Ribs
Click on this button to tick all ribs to be printed.
Print No Ribs
Click on this button to mark all ribs to not be printed.
Skin Thickness
Click on this button to edit the skin thickness of a rib. Select a rib by first clicking on a rib in the list. Alternatively double click on a rib. The Edit Skin Thickness screen is shown below.
To apply the skin thickness to all ribs, click on the Update all Ribs checkbox. Click on the Ok button to accept the change or click on the Cancel button to exit without making any changes.
The changes will be applied to the database so that the changes are permanent.
The Skin Thickness can also be set in the Rib View screen.
There are a number of print options available. These are as follows;
Rib Number
Print the number of the Rib. Ribs are numbered sequentially starting from the root of the wing and ending at the tip of the wing.
Rib Length
The length of the Rib is printed with the selected units of measurement.
Wing Specifications
The wing specifications are printed. These include;
1. Wing area
2. Wing aspect ratio.
3. Mean aerodynamic chord length and position.
4. Measurement units.
5. Type.
6. Wing root airfoil section.
7. Wing tip airfoil section.
8. Number of ribs per wing half.
9. Rib spacing.
10. Each rib number, length and distance from the leading edge reference line
X Station
This is the distance horizontal distance spanwise from the wing root.
Grid
Selecting this option prints a grid over each rib with stations marked at ten percent intervals.
New Page after Each
Selecting this option will result in each rib being printed on separate pages.
Start Distance
Select this option to print the distance from the leading edge reference line
Wing Planform
Select this option to print the wing planform with the mean aerodynamic chord position and the rib positions. Selecting this option will cause the WING PANEL PRINT SELECTION SCREEN to appear.
Print Resolution
Varying this will alter the degree of accuracy of the airfoil plot.
10 - rough plot , 100 - fine plot.
Increasing this number will also increase the time required to plot the airfoil.
Print Preview
This feature allows the specification, wing or tail design and ribs to be previewed before printing.
Print to DXF File Button
Cancelling the Print Job
A dialogue box will appear after the PRINT BUTTON is clicked on indicating the progress of printing.
You may cancel the print job at any time by clicking on the CANCEL button or if this dialog box has disappeared by deleting the print job in PRINT MANAGER.
