This DAT.xls file provides helpfull tool for visualizing existing DAT files or creating your own DAT files.DAT file is text file that contains normalized coordinates of desired shape. (To obtain normalized coordinates from absolute coordinates, just divide all coordinates (both x and Y) with largest X coordinate.That will bring all coordinates to the range from 0 to 1.)First row contains notes and is ignored by the software, following rows contain X and Y coordinates of points, which when connected will create desired airfoil (shape).Airfoil (shape) always starts and finishes in point 1,0.
Sample of the file:
E:\dat\CLARK-Y.dat: 1 00.99 0.0029690.98 0.00533350.97 0.00768680.96 0.0100232. .. .. .0.96 -0.00206830.97 -0.00170110.98 -0.00133390.99 -0.00096661 0
Feel free to enter your own coordinates or try to modify coordinates in following tabs and watch as shape changes.
