I think I told you that camo would grow on you! I just love that whole bird, she is so gorgeous, and that paint brings out her finer points, kinda like the right dress on the prom queen!

I wonder what did the twitter post mean by "launch". Is it the first ground test on a rig? Or a take-off of a test aircraft (flanker, PAKFA etc.) mounted with the new engine? Another possibility is engine in the air by mounting on a test-bed aircraft, though that is essentially in the same league as a ground test.
Good question, although flying the engine on a test bed aircraft is far more helpful than any ground test could be, by replicating actual airflows within a "cowling", cooling and airflows and pressures are far more accurate.
I was thinking of the development stage of this engine. So far what I know of engine development test goes such:
firing and running core on rig -> whole engine (with fan and afterburner) on rig -> high altitude test bed aircraft -> target aircraft or similar jets.
My intension is to compare with the progress of WS-15, in a broader sense to get a feeling of where the two countries jet industries are.
good post b787, and from a fairly "substantive source", with very specific details, and a much higher quality translation, so a lighter, simpler, more robust hot section, where we will see 15-20% improved thrust and efficiencies over the 117 for the article 30 engine. NOW THIS is a much more believable source than we normally see, and this will give the -2 much improved performance and fuel economy!
