TR Air-Force TF-X KAAN Fighter Jet

[Iskander]

I repeat for the people the information:

TUSAS has a serious problem with horizontal stabilizers on KAAN.

Two foreign companies were hired for assistance. In fact, both approached the problem and completed a report stating that the problem with these stabilizers, as they are, is technically unsolvable.

https://www.google.com/url?sa=t&source=web&rct=j&opi=89978449&url=https://www.youtube.com/watch%3Fv%3DZ5Z7sgZkYvA&ved=2ahUKEwiY0ePtxP-XAxXtJRAIHfYHJN4QwqsBegQIDhAB&usg=AOvVaw28zvfnb3-WFvcTjFkG2Ec1

In my view, this is precisely where the first suspicions arose—literally from the very first minute of the Kaan’s maiden flight. No one on the forum dwelled on it, as it was far from the most significant aspect.
It seems the concerns regarding the Kaan’s horizontal stabilizers stemmed from the fact that, early in the flight, they began to oscillate with a rather large amplitude. Given that this was the fighter’s first flight, such minor issues are entirely typical.
What actually happened? To put it simply—without diving into complex technical analysis—the Kaan’s onboard computers essentially "erred on the side of caution," building in a much larger safety margin than was strictly necessary. That’s all there was to it!
By the second flight, everything had been corrected, and no further noticeable oscillations occurred. In fact, this is precisely why numerous test flights are conducted—often over the course of several years—to identify and iron out such nuances.
This is a perfectly normal occurrence—so normal, in fact, that it cannot even be classified as a "problem."
