The word that seems to be missing from this thread: oscillations
So when I'm constantly making micro adjustments to the cyclic, it would soon get hard to manage as without dampening, nothing would be prevent my input corrections and over-corrections from adding up (e.g., I pull back, but went too far, so push forward, when actually I should have waited a second or two for helo to respond to initial back pull, instead, end result was that I was pushing forward when helo was also pitched forward, etc., ad infinitum, until someone in a village below you calls the local radio station and reports some "porpoise-like" object flying through the sky. It's much easier when the inputs are dampened and the oscillations cancel each other out, or are lessened in some way. Not sure how it actually works mechanically or electrically or pneumatically, or hydraulically, however it may be in the Ka-50.
From an article about tight-rope walkers:
He designed a means of safely anchoring both ends of the cable both at Niagara Falls and the Grand Canyon where no suitable infrastructure existed. Perhaps most notable, he designed an innovative means to stabilize the cable and dampen oscillations. Highwires in a circus tent or at an amusement park are only 30-50 feet above the ground, and are stabilized with a system of guy wires attached from the main wire to the ground below. This is clearly impractical at the heights of Nik Wallenda’s stunts. “Michael designed a solution wherein the cable is stabilized with a system of pendulums made of weights suspended by smaller cables attached to the main cable. The engineering problem was to determine the number, spacing, length and weight of these pendulums needed to counter the effects of wind and the vertical oscillations created by Nik’s steady cadence as he crossed the wire.”
