Description

Airfoil DAT Optimizer reads DAT files line by line. It copies only the points closest to each 5% of the chord and more frequently as 2.5% and 1.25% near the leading edge of airfoil. Instead of hundreds of points in the original file you will get 61 points in an output file. This will be more than enough to build a precise spline of airfoil without degradation in performance.

  • Cool, but sub-optimal.

    Take the demo for example - it made 61 points, but you only need 15 points to represent the original airfoil to an accuracy of better than 99.9999% - these are them:-

    p.s. also, it's not your fault, but, that is a garbage airfoil that nobody should be using anyhow. It "performs" badly across the board - but is "best" at Re 1,000,000 - however there's 10 stock foils in the UIUC database that outperform it there: - fx049915 in particular is 25% more efficient - and that's not even starting on actually running an optimizer for whatever Re range you really need... probably the word "Optimizer" should not have been used for this add-in - it's just a shrinker.

    Thank you for this app. It makes it much easier to use several airfoils without slowing Fusion extremely down.
