The Russians appearently don't much care for using aligned serrations on the edge of plates and panels to reduce X-band signature from most directions.   Wonder what effect that has on its signature.

hmmm... based on the discussion in paralay

the choice of using ejector nozzles seem to reflect a sustained cruise of M>1.5 requirement but the gain from such a design is best at M>2 though it suffers from subsonic performance

Looks like T-50-2 is going to test the OLS optical systems.

Cropped photos to just the T-50-2 for ease of viewing.

Comparison to T-50-1 - a few differences in panels and probes, plus the canopy and OLS, overall the rest looks identical.

Here's a nice picture (from Paralay's board) with the "news" marked.

Nice to notice that they are so quick with additional testing ... another proof in the confidence to that design.

Besides that - since I lost a bit the current overview - is there a source/link where the current status of the flight testing is summarized (how many flights, flying hours, reached test objectives and so on) ??

Thanks in advance,

no, I think that preparing something like quarterly "JSF facts" is out of business for Sukhoi PR Dept.

 :-[ Hmm ... sad, but understandable !
However is the an unofficial overview of how many flights, flying hours and so on made by some "Spotters" or "Enthusiasts" ? ???
