V-8, M.L.Mil
 |
V-8 was intended as a 25-seat passenger helicopter for over 300km stage lengths. Development of the piston-engine Mi-4 helicopter into free-turbine powered aircraft was an obvious move after success of the Mi-6. Development was done in parallel with similar transformation of the Mi-1 into Mi-2, but was more radical. The tailboom, rotor blades and hub originally retained, but the rest was new. V-8 was powered with single 2700hp Soloviev free-turbine.
First public flight took place on July 9, 1961 at Tushino. On 17 September 1962 the second prototype with two 1200/1500hp Izotov engines was flown still with the hub and 4-bladed Mi-4 rotor. Finally in 1964 five-blade rotor with Mi-6-style rotorhead were installed and aircraft was accepted for production as a Mi-8.
It became the most built medium helicopter, still in service all over the World.
