           El proyecto del Mi-12 comenzó en 1965 con
        la meta de producir una aeronave de despegue vertical con capacidad de
        transportar misiles u otra carga compatible con los cuatro motores del
        An-22. La oficina de Mil eligió la configuración del rotor lado a
        lado, para utilizar el rotor y la transmisión de los helicópteros Mi-6/Mi-10,con
        las menores modificaciones posibles. Los motores fueron cuatro turbinas Soloviev
        D-25VF de 6500 SHP (otras fuentes indican 5500 HP) cada una, montadas de
        a dos en las punteras de cada ala. El helicóptero alcanzaba una
        velocidad de 260 Km/h, con 35400 Kg. de carga y un alcance de 500 Km. El
        área de carga medía 28,15 m de largo por 4,4 metros de ancho, pudiendo
        transportar diferentes tipos de cargas. El fuselaje era del tipo
        convencional, semi-monocoque, con una puerta trasera de carga que se abría
        en dos, para facilitar la carga. El cockpit se encontraba en el piso
        superior de la cabina y contaba con una tripulación de 6 personas. En
        tierra, el helicóptero estaba soportado por un tren de aterrizaje
        inmenso, del tipo triciclo fijo, con dos ruedas en cada soporte. En el
        cono de cola tenía un timón vertical y otro horizontal con superficies
        de control móviles.  Así como fue diseñado para uso militar, también estaba previsto que lo usase Aeroflot, especialmente en lugares como Siberia, la cual es rica en recursos pero con muy malas vías de comunicación. Los problemas técnicos fueron ciertamente los responsables de que el desarrollo de esta aeronave fueran suspendidos a favor del Mi-26. Se construyeron solo dos ejemplares.  |

       The Mil Mi-12, known as V-12 in the Soviet Union, and by the NATO reporting name Homer, is so far the only helicopter produced by the Mil bureau to depart from the single main rotor plus tail rotor formula. It is to date the world's largest helicopter and flew for the first time in 1968, but did not enter production. The second prototype, which was presented in the West at the 1971 Paris Air Show, set seven load-carrying records in 1969: in February, a 31030kg load was lifted to 2951m and the following August, 40204kg was taken to 2255m. The Mi-12 project was started in 1965 with the
      aim of producing a vertical take-off aircraft capable of carrying missiles
      or other loads compatible with those of the four-engine An-22. The
      bureau chose the side-by-side rotor formula in order to use the
      engine-transmission-rotor assembly of the helicopters of the Mi-6 /
      Mi-10 series with minimal modifications. Two of these assemblies
      were in fact mounted at the tips of the two short wings, which had an
      inverse taper from the root to the wingtips. The engines were 6500shp
      (5500 shp other sources) Soloviev D-25VF turbines giving the helicopter a
      maximum speed of 260km/h, with a 35400kg load and 500km range. The large
      cargo hold measuring 28.15m long by 4.4m wide could take various kinds of
      loads, including very bulky ones, as well as troops or handling crews. The
      fuselage had a conventional, semi-monocoque structure, with large
      clamshell loading doors at the rear to facilitate handling of bulky loads.
      The flight deck was on the upper floor of the cabin and there were six
      crewmembers. On the ground, the helicopter was supported by large, fixed
      tricycle landing gear with two wheels on each unit. A large end-plate fin
      tail unit was mounted at the rear of the fuselage, with moving vertical
      and horizontal surfaces. As well as being designed for military use, the Mi-12
      was probably intended for service with Aeroflot, especially for deployment
      in areas of Siberia which are rich in resources but which have very poor
      communications. Technical problems were almost certainly responsible for
      development of this aircraft being abandoned in favour of the Mi-26.
      Two prototypes were built. G.Apostolo
