AS504X Airfoil Coordinates

These airfoil coordinates are plotted by using the number in the first column as the x coordinate and the number in the second column as the y coordinate. Disregard the column of zeros. They're there because I loaded these into a 3D CAD program to generate the airfoil templates, and they're required for this particular software to work properly.

First, the coordinates are scaled to the appropriate chord length by multiplying the numbers below by whatever chord length you need (the numbers below are based on a chord length of "unity", or one inch, or one centimeter, or whatever units you measure your chord in. In the case of the root of the KR2S, they would all be multiplied by 48", or multiplied by 30" at the tip.  There is nothing more to these than simply plotting out the x and y points on large graph paper (or 2D CAD system) and then connecting the dots with a bspline curve. The X axis it the chordline, from which the incidence will then be measured. In the case of the unity coordinates below, the chord line would extend from 1,0 at the leading edge to 0,0 at the trailing edge.

The following coordinates are for the AS5045 airfoil.
