Mil V-12
The Mil V-12 (also known as the Mi-12) is a heavy transport helicopter created in the USSR in the late 1960s. The V-12 is the largest rotorcraft ever built and flown. The V-12 – the brainchild of the Mil design bureau, was created as a heavy transport for lifting heavy and large equipment in a pair with military transport airplanes. The result of this concept was a truly amazing helicopter in terms of size, weight and carrying capacity. In terms of dimensions, it is comparable to large airplane, and in terms of mass, it is many times greater than any other helicopter, including modern ones. Its distinctive feature is the transverse arrangement of the twin rotor power plant – two pairs of engines and propellers are installed on the tips of a large reverse narrowing wing. The V-12 has a large fuselage, a double-deck cockpit and a cargo compartment, dimensions of which are close to the cockpit of that time’s giant An-22 Antey.
