This function allows airfoil coordinates stored in the Winfoil Database to be exported to comma delimited ascii files for use in other programs or for transferring data between different versions of Winfoil. Two options are provided with this function;

1. select a particular airfoil - select from the dropdown list

2. select all airfoils for export - click on the check box


To export;

1. Select click on the Winfoil Coordinates radio button.

2. Select an airfoil from the dropdown list or click on the All checkbox.

3. Click on the Ok button.


Two data files are produced by this function;


1. Airfoil Data File 

This file contains the airfoil name, maximum lift coefficient, minimum drag coefficient and maximum pitching moment coefficient. An example of the file layout is shown below. Please note the comma after each value and the comma at the end of each line. 


CLARK Y,0.00,0.0000,0.0000,

CLARK YH,0.00,0.0000,0.0000,


 This data format is identical to the export format of the earlier versions of Winfoil.


2. Airfoil Coordinate Data File

This file contains the airfoil name, upper x coordinate, upper y coordinate, lower x coordinate and lower y coordinate. All coordinates are expressed as percentages and all values are separated by commas with a comma signifying the end of each line.


Example shown below.

CLARK Y,000.0000,003.5000,000.0000,003.5000,

CLARK Y,000.5000,004.5500,000.5000,002.8000,

CLARK Y,001.0000,005.2000,001.0000,002.3000,


Data can be saved as a back-up for future use. This data can be used to recover in the case of hard disk failure or other hardware problems which cause data loss.
