That sounds like an interesting and ambitious project depending on the level of accuracy you require. One CFD product in the academic and commercial market is Ansys. A preliminary challenge would be to acquire a reasonably accurate model of the 182 (including the body) if you haven't already done so. Perhaps that could be done with photogrammetry or a LiDAR scanner. Getting it from the resulting point-cloud to a CAD solid-model is relatively straightforward but not sure what the workflow is to get...

Andre is the actual author of the tool, so if he says this analysis is unsupported then it's unsupported. To form a reasonable intuitive sense of the added drag in your airplane you could do experiments in the aircraft itself. In the early morning (i.e. with no thermal or convective activity), from a reasonable altitude (e.g. 5,000 AGL), with a consistent weight and balance including fuel level, set your engine to idle (with carb heat if it's not fuel injected). Trim to a certain airspeed and note...

The video is interesting but tough to interpret, except in the most general conceptual terms. The video shows that the camera brings forward the line of separation and converts a chunk of the flow on the surface of the wing from laminar to turbulent. The camera is effectively acting like a minature airbrake (see also 6:20 for comparison), taking all (and more) of the drag that the surface of the wing behind it would normally bear. In terms of the pressure distribution (and lift), the reason for the...

Check out this master's thesis on the same topic. The student determined that data gathered through flight testing provided the gold standard, and identified significant gaps with the various analytical and CFD methods attempted. (The drag turned out to be much higher than predicted by a rudimentary CFD flat-plate-based model.) The camera/instrument was large even relative to the aircraft in that study. For the GoPro, you might try one or more of these techniques. https://trace.tennessee.edu/cgi...

Thank you for candidly sharing your perspective and plans. I take it from your last point that your involvement with other commitments and projects may preclude the release of a refactored version 7? It seems like an impressive and even important project, but I recognize that there are only so many decades of one's life that one can contribute to even the most impressive of projects.

Thank you for responding quickly. Yes, I can see that resolves the problem. Many thanks. There is a YouTube video out there with 5,000 views that does not help matters, because it is clearly working with a file in the Lednicer format. https://youtu.be/Wl95co7KVg4 Moreover, the major academic database does not offer individual files in dual formats, but rather in whatever format the item was originally contributed/acquired. https://m-selig.ae.illinois.edu/ads/coord_database.html I suppose at some...
