It does seem like a press blurb, but if true then it represents a pretty quick turnaround from the detection of cracking, to a fix, to a continuation of the test program. Do we have any idea of how serious an issue this was in the first place?popcorn wrote:johnwill wrote:popcorn wrote:http://www.defencetalk.com/sukhoi-t-50-stealth-fighter-completes-tanker-plug-trial-44288/
Apparently, they've managed to fix the structural problems that plagued PAK-FA #1.
Quite possibly they have, but the tests described in the link do not require high g maneuvering. Until we know what the maneuver limits are, we don't really know if the problems have been solved or not.
From the linked article :
...The first prototype, T-50-1, is undertaking preparation for a flight test program involving flight at super-critical angles of attack and super-maneuverability...
Presumably this aspect of testing will stress,the aircraft significantly . Any significant differences in the way the Russians approach development and testing vs. the West?
