Design and development
Development came about as a need for a heavy lift helicopter capable of carrying major missile components. Production began on the V-12 prototype
in 1965 with the goal of lifting no less than 30,000 kg.
The first prototype made its first lift-off on 27 June 1967. After a few oscillations in close proximity to the ground the V-12 made a rough touchdown on one wheel resulting in a burst tire and a bent wheel disk. Even though the damage was insignificant, it was reported in the Western press that the prototype had suffered severe damage, and even to this day the rumor persists that the prototype had crashed fatally.
The V-12 features the only two-rotor transverse scheme ever built by Mil, eliminating the need for a tail rotor
. The twin engines were taken together with the rotors from the Mil Mi-6
and duplicated on the V-12. Being the first time used by Mil, the twin rotor transverse scheme... Read More
