I had to see the videos to actually comprehend what was being reported.
Unbelievable. NO UNTHINKABLE! The 'shaking/flapping' appears to be linked with wings weapons loads. The flapping appears persistent thru most of the low speed range, so releasing free-flight ordnance must be a 'crap-shoot'.
Russia’s Ka-52 Attack Helicopters Have A Serious Vibration Problem
Videos show significant vibration on heavily laden Ka-52 Hokum attack helicopters and experts don’t like what they see.
Russian Ka-52 Hokum attack helicopters fighting in the war in Ukraine are suffering from a major vibration issue that could, according to at least one expert The War Zone consulted, decrease reliability and, potentially, be unsafe. At best, according to assessments we’ve received, the vibration is likely to reduce the efficiency of the weapons these helicopters carry, and may also restrict weapon life. In turn, this could have an effect on the capability of the Ka-52, one of the most widely used Russian helicopters of the conflict so far.
Video clips showing Ka-52s operating with their stub wings rapidly bouncing up and down began to appear on social media in recent weeks and there has already been speculation that the issue could lead to “mechanical failures and vibration-induced fatigue.”
