The language written in the article in the above link is in Russian...can't understand anything.......but what actually happened?...the heli in the second image seems to be on fire I believe...was it an accident as the topic itself tells ''Shooting rotor blades''?...

In the first pic you can see the pilot escaping the heli, so that someone (presumably on the ground) shoots the rotor blades, apparently destroying the aircraft, as seen in the second pic.

I think it's a test for the heli's use in combat, but I'm not sure. :P

I contacted Ucon about this one as well. The 1957 (or 1958? There's conflicting sources!) trial was exactly as described, and it was done for an emergency escape vehicle crew to see how the helicopter would survive without all of the rotor blades.

Um... i made an error. While looking up the Ka-50/52 ejection system for the helicopter escape system thread I came across the site below also talking about this Mi-4 test... "shooting" blades refers to the blades "shooting" off of the hub. Mistake in translation i guess. :P  (but why would Konstantin confirm the misunderstanding as fact??)

basically it was a test for jettisoning blades from the hub to evaluate future escape systems such as the K-37-800 on the Ka-50/52 series. This Mi-4 was mentioned in the other thread too but for some reason i didn't connect the two until now.

Translated text: The pilot tests for the shooting of the blades were carried out on a Mi-4 helicopter with a depleted flight resource. The test pilot took the helicopter to a predetermined height, turned on the autopilot, then got out of the co.ckpit and left the helicopter with a parachute. As soon as the test helicopter moved away from the pilot to a safe distance, on the command from the accompanying helicopter on the Mi-4, the rotor blades were fired, after which the machine went into a random fall and crashed. Nevertheless, the researchers were able to observe how the blades behave after separation from the sleeve, at what speed they move away from the helicopter. These data made it possible to calculate the moment of the beginning of the bailout, which was very useful in further work. As a result, the first ejection seat for helicopters, the K-37-800, was created in the USSR. For the first time, a seat was installed on an active helicopter in the late eighties - on the Ka-50 experimental vehicle with number 05, which became the standard for mass production. It is worth noting here that the Ka-50 helicopter became the world's first serial combat helicopter with an ejection rescue pilot system.

Holy crap, thanks for the research effort! Nice to get more material on this one. That video especially made my day.

I'm also wondering why Kostya went with this mistake. Details lost in translation from the language barrier? He usually is pretty accurate with his info. Probably an honest mistake. Or maybe he was being sarcastic, who knows, LOL.
