XFLR5 is probably not the right tool to analyze any blended configuration. It focuses on traditional airframes, and the fuselage modeling is limited.

XFoil historically has its own discussion group on the Yahoo! platform, at https://groups.yahoo.com/neo/groups/xfoil/info Sent from my iPad On Nov 9, 2019, at 10:46 AM, Karim Sayed Abdelwahed Ahmed karimsayed12@users.sourceforge.net wrote:  I couldn't find a discussion group on this webste for the original XFOIL, and since XFLR5 depends on Xfoil for solving the flow over the airfoil, I thought it would be the place for such a question.

You do realize this is not the XFoil discussion group, right?

After some iterations, the results become unrealistic for some airfoils, although when I solve those airfoils on XFOIL separately from MATLAB, it gives the correct results.

Not necessarily. An airfoil can be pitch-unstable. A flying aircraft will likely be stable to fly.

It’s because you have “Fin” checked in your plane definition window, but you actually have no fin as the Blade has a V-tail.

I think most users of this forum only use English. Anyway, TE is “trailing edge”, and LE is “leading edge”.

Direct analysis = 1 operating point at a time Batch analysis = multiple OpPs in a batch, sequentially Multithreaded batch analysis = same as above, but on multiple threads.
