This screen is used to add, change or delete airfoil lift and drag wind tunnel data for any number of Reynolds numbers. 

To add data;

1. Add a new Reynolds number grouping by clicking on the ADD REYNOLDS button. Enter the Reynolds number and click on the OK button.

2. Add lift and drag coefficient data by clicking on the ADD button on the lower right section of this screen.  This will cause the Add Lift/Drag data  screen to appear. Enter the data as required. To enable auto updating of data, click on the AUTO UPDATE checkbox.  This will cause data to be updated automatically after you tab off the drag coefficient text box. This saves you the effort in clicking on the UPDATE button each time you want to save data.


To change data;

Click on the CHANGE button on the lower right of the screen.


To delete lift/drag data;

Click on the DELETE button on the lower right of the screen.


To print data;

Click on the PRINT button.


To view a graph of the data;

Tip  Data is always entered for a Reynolds number set. To add a new set you must add the Reynolds number first , followed by the lift, drag and angle of attack data. To view the data for a different Reynolds number, click on the Reynolds Number Grid at the upper left of the screen.

A quick way to edit existing lift/drag data is to double click on the data row in the lower grid.
