The development of heavy troop-transport helicopter Mi-6, which began in 1953 year, defined for many years the leadership of the domestic helicopter industry in the development of heavy-lift helicopters. Mi-6 on its flight characteristics, established joint tactical and technical military and civilian requirements 1954 year, significantly superior to all foreign helicopters, It is a qualitative leap in the development of world helicopter.
MI-6 – video
Used for the Mi-6 layout scheme with two gas turbine engines and the fuselage with a large cargo cabin and a rear cargo door has become a classic, repeating in many domestic and foreign helicopters, and developed unique rotor diameter 35m, providing a helicopter taking off from the maximum takeoff weight 48T, and the main gearbox, transmitting power from two turbine engine 8090kVt, were the outstanding achievements of science and technology. Combined support system was used to ensure high flight speeds in the Mi-6 helicopter with a wing, unloads rotor.
The first of five experienced helicopter made its first flight 5 June 1957 of the year, a 30 October this year at the pilot of the Mi-6 helicopter was set international records lifting maximum load 12004kg a height of 2432m, It shows the enormous potential of the helicopter, and marked the beginning of an outstanding international absolute records, mounted on Ni-6.
In the course of joint research by the army and the State aviatsinnoy Technology Committee, conducted in 1959-1963 years, it was found 16 international records, including absolute records: load 5000kg lift to a height of 5584m and a maximum load 20117kg at a height of over 2000m; The speed 300.377km / h on a closed route of 1000km with 5000kg truck; The speed 315.657km / h to 500km route closed; speed of 320km / h on the basis of 15-25km and, finally, Speed 340.15km / h to 100km route closed, established 26 August 1964 year and remains unsurpassed to date. These records made Mi-6, not only the load-lifting, but also the fastest helicopter in the world. AT 1961 year for the absolute speed record of 320km / h, mounted on the helicopter Mi-6, American Helicopter Society ML Design Bureau. Mil was awarded the International Prize named I.I. Sikorski “as recognition of the outstanding achievements in the development of the helicopter art”.
At the end of 1959. It began mass production of the Mi-6 on the Rostov Helicopter Plant, continues in 1981., as well as to plant them. Khrunichev in Moscow; all were built 860 helicopters for military and civil variants, posed by the Soviet armed forces and civil aviation, as well as abroad: Vietnam, Egypt, India, Indonesia, Iraq, China, Peru, Poland, Syria and Ethiopia. A variant of the Mi-22 – air observation point with a big antenna on the tail boom.
Design
Single-rotor helicopter adapted scheme wing, two gas turbine engines and tricycle landing gear.
Fuselage
all-metal, frame structure. cabin located in the bow of the crew, Front for the navigator, average for the two pilots and back to the wireless operator and borttehnika. In the central part of the fuselage is located cargo cabin dimensions 12 x 2.65 x 2.5 m and a volume of about 80m3, cargo door dimensions - 2.65 x 2.7m with an opening in the side wings and the loading bridge, designed for the carriage of goods weighing up to 12t, or to 65 passengers on folding seats (in extreme situations in the cockpit was transported to 150 passengers), or 41 the wounded man on a stretcher with two nurses on folding seats; on the right side of the cockpit door and located nine windows, on the left - two doors and seven windows. The cargo compartment floor has a cargo door, closing flap.
The tail boom
semi-monocoque design, otdelyaemaya, is attached to the fuselage with bolts, end end beam. On the tail boom mounted control fins, but in the end the beam - fixed rudder.
Wing
split, It has a center-beam and console caisson spar type, nose and tail pieces and ending. The wing is designed for a maximum load, equal 25% flight weight, TSAGI P35 has a profile with a relative thickness at the root 15% and at the end 12%. The left bracket has an angle of 15 ° zaklineniya14′, and the right - 15 ° 45′.
Chassis
tricycle, fixed landing, a liquid-gas springs; front support with two caster sizes 720 x 310mm; main pillars shaped type have only one brake wheel sizes 1320 x 480mm and pressure 7 kg / cm2; on the tail boom has a tail wheel; chassis allows vertical takeoff and landing and the airplane type.
main rotor
five-blade, with hinged blades and hydraulic dampers tilted forward 5 °. The blades are all-metal construction, a rectangular shape in plan, with profiles NACA 230M and the relative thickness TSAGI 17.5% and at the end 11% at the end and an angle 6 ° zakrutki-. Horde Blades 1m. The blades have a steel spar made of solid steel tube cold 40HNMA 15.61m length with varying wall thickness and the cross sectional shape. By spar attached 20 sections, consisting of the bow with a counterweight and icing bag and a tail part with honeycomb, and an end cone. The blades have an electrical anti-icing system, the peripheral speed of blade tip of 220m / s.
The tail rotor
