MI28 vs Ka50

[Russian Texan]

Couple of weeks ago there was a topic somewhere on this message board about these two helicopters. I just found some videos of them, take a look

My all time favorite - Mi35 (Mi24 evolution)

And as a bonus Mi8

There were some good videos of KA-50's firing S-8 rockets at terrorist camp somewhere in Chechnya, a couple of months ago, too bad I can't find them anymore..

hmm....thats weird i noticed the Ka-50 does not have a rotor in the back like most choppers have, does this have something to do with the fact that it has a 2 sets of rotors?

Yeah, most helos need the back rotor to compensate for the torque produced by a single main rotor. On the Ka-50 and other twin-main-rotor heols, they counter-rotate (one goes clockwise, the other counterclock) thus balancing out or negating the torque produced by the other.

wow I'm very impressed. Thosse were easily the best videos I have seen on this site

Tail rotor is one of the most vulnerable spots in a helicopter, if it gets hit then crash is inevitable. Twin rotors eliminate that problem.
Ka50 also has an ejection seat and I'm looking for the pics or a video of it in action, if someone has it please post.

Using a tail rotor means loss of power (more than 15% of power is used to power the tail rotor), plus tail rotors are the greatest killers of ground crew on the decks of ships operating helos and in small LZs.

The ceiling and ceiling out of hover for coaxial designs is much greater than for other helo designs as all power is going to lift the aircraft.
Also the main rotor blades can be shorter, which makes them more compact. There is also less inflght vibration and the rudder pedals can be used to turn the nose of the aircraft at any speed in any direction... this has led the designers of the Hokum to mount the cannon near the centre of gravity rather than under the nose in a turret... this greatly increases its accuracy and reduces the effect of recoil on the airframe.
