The Mil Mi-8 ( Russian Миль Ми-8 , NATO code name : Hip ) is a multi-purpose and transport helicopter with two turbine engines and large rear loading doors developed and manufactured by Mil in the Soviet Union . The models with the designations Mi-17 , Mi-18 , Mi-19 , Mi-171 and Mi-172 are considered variants of the Mi-8 . A close relative is the naval version Mi-14 , which is carried as an independent model .

history

The Mi-8 was developed and introduced as a replacement for the older, piston-engine equipped Mil Mi-4 . In 1957 the OKB-329 began specifying the characteristics for the new helicopter. Since Nikita Khrushchev gave priority to the development of missiles at this time, little money was available for the aircraft industry. Then served Mikhail Mil a white lie and presented the draft as "massive modification" of the Mi-4 turbine powered and new nose and fuselage section, which in all-metal semi-monocoque construction made of duralumin were manufactured. The tail boom, the drive train with the rotors, the flight control system and more should be taken over by the Mi-4. Since the civil Soviet aviation authority and the top of the Soviet military were interested in a new VIP helicopter in addition to the transport version, the design was accepted on February 20, 1958 and Mil started developing the W-8 (W for the Russian name for helicopter [Wertoljot / вертолёт]) commissioned. The helicopter should have a payload of 1.5 to 2.0 tons. To Mil's annoyance, a single turbine of the Ivchenko AI-24W type was planned as the drive , which is normally used in the An-24 and throttled from 2400 to 1900 hp for use in the W-8 to power transmission and the rotors of the Mi-4 to be able to use. The first prototype of the single-engine W-8 was completed in June 1961 and first flown on June 24, 1961 by Boris W. Semskow. Just two weeks after the first take-off, the helicopter, which can be easily recognized by its single air inlet, was presented on July 9, 1961 at the annual air show in Moscow-Tuschino . In December 1961 the helicopter was handed in for acceptance tests, and from 1963 it served as a test platform on the ground. A second single-engine prototype began flight tests in November 1961.

Mil saw the single-engine solution as inadequate in terms of safety and performance and pushed the development of a twin-engine variant W-8A. Since no suitable engine was available, the OKB-478 Isotow developed the TW2-117 . The first engines and the WR-8 reduction gear were delivered in the summer of 1962. The first flight tests with this helicopter were carried out on August 2, 1962 by N. W. Leschin, the first real flight followed on September 17, 1962, and just a few days later the helicopter was demonstrated to Nikita Khrushchev and high-ranking officials of the Warsaw Treaty Organization . Flight tests continued until early 1963, before the helicopter was handed over to Aeroflot for initial tests in March 1963 . In the course of the tests, various modifications were made, for example the four-blade rotor was replaced by a five-blade rotor with identical structure to reduce vibrations. The tail rotor, the de-icing system and the engine control system were also changed.

The third prototype W-8AT, completed in the summer of 1963, contained some changes that had resulted from the flight tests, and represented the actual test model for the civil and military transport variant Mi-8T. Among other things, the previous separate side doors for the pilots were made replaced by sliding windows, enlarged the rear doors and installed a kerosene-powered cabin heater in an extension of the external starboard fuel tank. The fourth prototype W-8AP, completed in May 1964, served from the beginning as a test sample for the later VIP version and for the later passenger version Mi-8P.

After the four prototypes, approval for series production was recommended in November 1964, granted in March 1965, and at the end of 1965 the first series helicopters Mi-8P and Mi-8T rolled off the assembly line in Kazan . The test pilot of the first W-8A, Leschin, was killed in a test flight with a Mi-8 in January 1966 when his helicopter became uncontrollable due to a failure of the tail rotor and crashed.

Since then, more than 12,000 Mi-8 helicopters in more than 120 versions have been built; the helicopter is constantly being developed and is still in series production. The Mi-8 versions were manufactured in the State Aircraft Plant No. 387 in Kazan (more than 7,300 pieces) and in the State Aircraft Plant No. 99 in Ulan-Ude (more than 3,800 pieces), USSR.

The drive and airframe were incorporated into the design of the Mi-24 attack helicopter . The Mi-14 is a marine version developed from the Mi-8, which can be recognized by the boat-like floating hull (which has a separate weapon bay for torpedoes and depth charges). However, due to the complete redesign of the fuselage, it is practically a new development and thus an independent model. The Mi-38 is also based on the Mi-8, but is equipped with western engines and modern avionics .

Mil Mi-8T of Interflug, cockpit

The Mil Mi-8, originally developed as a transport helicopter, quickly demonstrated its suitability for a wide variety of uses, such as ground support with rockets and cannons, also in combination as an attack helicopter. It has a load suspension so that it can lift up to three tons under favorable conditions. There is also a personal rescue winch for loads up to 250 kilograms. Basically, the Mi-8 was divided into three versions: the transport version Mi-8T, the armed transport version Mi-8TW and the variant with special equipment Mi-8S.

hull

The conventionally constructed fuselage consists of four sections (fore and middle fuselage, tail boom and tail rotor boom) and is made of duralumin as an all-metal half-shell construction. The tail boom can be removed for maintenance purposes and transport. The cockpit section originally had five windows in the upper row and four in the lower, although the design of the lower row later varied as a result of the installation of a PKT machine gun, weather radar or armor. The three middle windows in the top row consisted of optically flat glass and contained an electrical de-icing system. The two side windows of the upper row were designed as outwardly curved sliding windows made of Plexiglas. The cockpit was equipped with three instrument panels and a double mechanical flight control for the two pilots. The panels were arranged in such a way that the windows offered the best possible all-round view. The transport / passenger area was separated by a door opening to the cockpit, with the flight engineer having his place in the corridor to the door. On the outside of the fuselage between the cockpit and the door or the first window, there were two flaps on each side for access to the helicopter's battery compartments.

In addition to the cabin, the engine system is also located in the central fuselage. In the case of the transport versions, a car can also be driven into the 5.34 m × 2.25 m × 1.8 m fuselage, which is designed for a load of up to four tons, on tracked tracks. A load bearing for up to 2.5 to 3.0 t load (depending on the version) is located in the interior at four points on the ceiling frames. This has the advantage that the load engages approximately at the center of gravity of the helicopter and so the tendency to pendulum is reduced around the point of load introduction. The load rope is led down through a hatch in the cabin floor. There is also a winch on the door for a load between 150 and 250 kg. The cabin of the Mi-8P / Mi-8PS / Mi-172 versions is 6.36 m long, 2.05 m wide and 1.7 m high, that of the Mi-8MTW-5 is 6.36 m × 2.34 m × 1.80 m. Access to the cabin is a sliding door that can be thrown off in an emergency and opens to the rear and is 1.4 m × 0.62 m in size on the left-hand side. In addition to military use, many Mi-8s are still used for civilian transport or as VIP helicopters. For the latter, a door that hinged down and also served as an entry staircase was sometimes used. In some later versions, a sliding door was installed on the right side. Depending on the version, there were five to seven windows on each side, with the passenger versions mostly having rectangular windows and the transport versions having round windows. At the stern there were two-part, side-opening and removable rear doors. When closed, the hull had a length of 7.28 m. One of the two rear doors was again equipped with a smaller door for evacuation in an emergency. On the fuselage side there were suspension points for the fuel tanks (initially 745 liters on the left and 680 liters on the right, later 1140 liters on the left and 1030 liters on the right), the cabin heater and / or air conditioning. With the military variants, different external load carriers were added depending on the version.

The conical tail boom made of metal with a circular cross-section ends at the tail rotor boom running upwards at a 45 ° angle with the gearbox for the three-bladed tail rotor with 3.9 m diameter, 260 mm blade depth and NACA-230M profile. The tail boom carries metal stabilizing surfaces with a 2.7 m span with a symmetrical NACA-0012 profile, which can be adjusted up or down by 9 ° on the ground. A decoy launcher can be attached to the tail boom for military use.

landing gear

The three-legged, hydropneumatically sprung chassis is not retractable, has a wheelbase of 4.26 m and a track width of 4.5 m. The main landing gear is equipped with individual 86.5 cm × 28.0 cm pneumatic braked wheels. The nose wheel landing gear has two tires with two 53.5 × 18.5 cm wheels and has neither brakes nor controls (it locks in the direction of flight without load). The helicopter is controlled on the ground by braking the main landing gear differently. The tail boom (and thus the tail rotor) is protected from contact with the ground by a small springy tail spur.

Main rotor and drive

The main rotor is five-bladed and is located directly above the two drive turbines lying parallel to each other above the cabin . When viewed from above, it rotates to the right (clockwise) and has flapping and swivel joints with hydraulic dampers. The replaceable blades made of aluminum with steel leading edges and a de-icing system have a constant blade depth of 520 mm and a NACA -23012 profile. The two drive turbines, which are identical except for the arrangement of the exhaust pipe, are designed in such a way that a flight can be continued with restrictions even if one turbine fails, since the other can provide the additional power. Different versions of the Isotow / Klimow TW2-117 or TW3-117 engines are used, which provide between 1500 and 2200 HP take-off power and use kerosene of the type T-1, TS-1 or T-7P ( Use JP-1 or JP-4 ). The three-stage main gearbox is attached behind the engines, behind this in turn the power take-off for the hydraulic system and the hydraulic block itself. The main gearbox reduces the maximum input speed of the engines from 12,000 / min to a maximum of 192 / min for the main rotor, 2,589 / min for the tail rotor shaft and about 6,000 rpm for the fan of the oil cooler for engines and transmissions. The tail rotor end gear has a reduction ratio of 2.3: 1; the tail rotor speed is around 1,124 / min.

On-board systems

The hydraulic system consists of a main system with 45 kg / cm² pressure and a reserve system with 65 kg / cm², which automatically takes over the control of the flight control systems in an emergency. The electrical system works with 12/48 volts and is supplied by two 48 kW starter generators GS-18TP and six 12 V / 55 Ah lead-acid batteries . The helicopter's electronic equipment consisted of a four-channel autopilot and various flight control and communication systems such as a radio altimeter, Doppler speed sensor, radio compass, UHF radio, IFF transponder, S-3M Sirena radar warning system and flight data recorder.

A total of more than 120 different versions were produced, each of which can be divided into two generations according to the engines used (TW2-117 or TW3-117). In addition to this large number of versions, which results from a large number of machines built for special purposes and as test samples, some exported models (for example those supplied to India and Finland) were retrofitted with special equipment such as a weather radar and then with their own version designation Mistake.

Prototypes

• W-8 "Hip-A": Prototype with an AI-24W engine, 2 tons payload, 18 seats and a range of 450 km. It had two additional doors for the pilots.
• W-8A "Hip-B": Prototype with two TW2-117 engines and 20 seats.
• W-8AT  : Prototype for the Mi-8T, but with rectangular windows
• W-8AP  : Prototype for the Mi-8P

Serial helicopter

• Mi-8T "Hip-C": The civilian version was first publicly exhibited in 1969 at the 27th Paris Air Show. The transport version is equipped with Isotow TW2-117 engines and round windows that open inwards and upwards. This enabled the soldiers to use their submachine guns in the military versions. Compared to the prototype, the doors of the loading ramp now had triangular lower edges that could be folded inwards into the doors in order to facilitate loading and unloading. The DISS-2 Doppler speed sensor is clearly visible under the tail boom. The helicopter can transport up to 4 tons internally or 3 tons externally. Seats for 24 passengers or 12 stretchers are installed in the fuselage. The Mi-8AT produced from the 1980s onwards corresponded to the Mi-8T, but were equipped with improved TW2-117AG engines that delivered 1700 hp take-off power and also achieved a longer service life. These machines were mainly supplied to regions with “ hot and high ” requirements. Other versions of the Mi-8 (such as the Mi-8AP) were also equipped with these engines. Versions with a new engine and the option of converting between transport and passenger version were designated as Mi-8TP. The Mi-8TM produced from the 1990s onwards also had the new engines, but were equipped with further improvements such as a "contour" weather radar instead of the lower middle cockpit window. Production of the Mi-8T ended in Kazan in 1986, in the other plant in 1999.
• Mi-8P "Hip-C": Passenger version for 28 to 32 passengers. It differed from the prototype W-8AP mainly by the rear cabin windows designed as additional emergency exits and the lack of small side windows on the pilots' sliding windows. The basic version had 28 seats (seven rows of two double seats each), with more comfortable 20, 24 and 26-seat versions being built later. Internationally, the helicopter was first exhibited in Paris in June 1965. The Mi-8P was mainly built in Kazan until around 1993.
• Mi-8PS or Mi-8S "Hip-C": saloon version with rectangular windows and a KO-50 cabin heater on the starboard side, which, depending on the number of seats (7, 9 or 11) and the interior, can also be used as a mini 8PS-7, Mi-8PS-9 or Mi-8PS-11. Many were equipped with additional communication technology, which was continuously improved in the course of production. Some of the machines built from 1969 on differed from the previous version mainly in the lack of a window on the left-hand side and the replacement of the sliding door with a door that fell down and also served as a staircase. This created space for the installation of an air conditioning system. The machines also had improved noise insulation, vibration dampers between the rotor blades and in some cases also an interior with armchairs, tables and a toilet. A six-seat version was also built, specially designed for long flights. Some Mi-8S were also converted from a Mi-8T at the customer's request. The designation as Mi-8S or Mi-8PS varies partially incomprehensibly, whereby especially the machines built from 1974 were designated as Mi-8S. At the end of 1970, the machines were equipped with more powerful TW2-117F engines, which produced 1700 hp take-off power instead of the 1500 hp of the previous engines. Since the first machine equipped in this way was delivered to the Japanese company Aero Asahi in 1980 , this version was named Mi-8PA (A for Asahi).
• Mi-8MB : Special version developed in 1973 from the Mi-8T version for evacuating victims of nuclear weapons attacks .
• Mi-8AW / Mi-8WSM : Version developed in 1975 from the Mi-8T for laying anti-tank mines. The Mi-8AD was developed in 1978 and was used to lay anti-personnel mines.
• Mi-8R / Mi-8GR / Mi-8TARG : reconnaissance versions developed in the mid-1970s. For the artillery and battlefield surveillance version Mi-8TARG with TV system, the frequently used designation Mi-8TG was also used. She was equipped with cameras with a focal length of 1000 mm or 1300 mm in the second window on the starboard side and an on-board developing machine.
• Mi-8WKP and Mi-8WZPU "Hip-D": In the early 1970s, machines converted from the standard Mi-8T for tactical battlefield monitoring and command (tasks similar to the later Mi-9). They can be identified by two antennas mocked as "towel rails" on the front part of the tail boom and electronic pods that are firmly attached to the weapon carriers.
• Mi-8TW "Hip-E": First version intended as a support and attack helicopter, which was produced from 1968. It initially carried the external load carrier developed for the Mi-4AW with four pylons for four UB-16-57U rocket pods or bombs weighing up to 500 kg. In the middle window of the lower row of the cockpit glazing, a PKT machine gun with a 7.62 mm caliber was movably installed in some helicopters . A simple crosshair attached to the tube was used to aim. The corresponding mounting options for the external load carrier were also available on all Mi-8T, so that they could be converted in an emergency. This option was used by some exporting countries. These specimens were called "Hip-C" in the West. The 1974 manufactured specimens possessed modified pylon for up to six UB-32 - rocket containers and four attached to the top of the boom 2K8-Falanga - anti-tank missile , which were directed by the co-pilot over a gyro stabilized sight. The Mi-8TW is often confused with the Mi-8TB , which comes from the Cyrillic letter "В" (= "W"). The Mi-8TB was a Mi-8 with additional armor.
• Mi-8TWK "Hip-F": Export version of the Mi-8TW with six 9M14 Maljutka anti -tank guided missiles instead of the four 2K8 and movable 12.7 mm machine guns in the bow.
• Mi-8TZ : Version produced from 1977 for the supply of fuel.
• Mi-8TL : Fire fighting version produced from 1977.
• Mi-9 "Hip-G": also called Mi-8IW variant as a flying command post (air-moving command post) with round windows (like Mi-8T) and a small rear door of the Mi-8P. The electronics on the ground are supplied with power by an Ai-9 gas turbine with a 24 kW generator. The prototype was built in Ulan-Ude in 1977 and series production began in 1978.
• Mi-8TG : Version for operation with liquid gas for the appropriately modified engine with the designation TW2-117TG. The corresponding research program was decided on March 6, 1979 by the Soviet Council of Ministers and implemented in cooperation with various institutes. A Mi-8T was converted into the prototype in 1987, which had its maiden flight on September 7, 1987. For this purpose, four small metal tanks for liquid methane were attached to external load stations taken over by the Mi-8TW. Later these were replaced by two large tanks each.
• Mi-8SMW "Hip-H": In 1971, an ECM version (electronic countermeasures) was developed from the Mi-8T, which was the first of a series of ECM versions. She carried the Smalt -ECM complex, which can be recognized from the outside by an antenna that replaces the second and last cabin window on both sides. Series production in Ulan-Ude began in 1977. The version has been improved several times over the years.
• Mi-8PP / Mi-8PPA "Hip-K": ECM and signal reconnaissance version developed in 1974 with six cross-shaped antennas each on the sides of the fuselage instead of the last cabin window, one antenna instead of the first cabin window and six coolers arranged in parallel under the fuselage, facing the Polje -ECM complex. Series production began like that of the Mi-8SMW in 1977 in Ulan-Ude. The Mi-8PPA contained the further developed acacia -ECM complex.
• Mi-8MT / Mi-17 "Hip-H": The most obvious difference, in addition to the more powerful new Klimow TW3-117 engines and many technical improvements, is the position of the tail rotor. On the Mi-8MT / Mi-17 it was placed on the port side (left in the direction of flight) and therefore no longer blows against the tail boom, which greatly increases its effectiveness. As early as 1964, the development of a version called the Mi-8M with increased take-off mass and a payload of more than 4 tons began. By extending the fuselage in front of and behind the main rotor, the seating capacity was also increased to 40. To compensate, the more powerful TW3-117 engines of the Mi-14 and Mi-24 under development should be used, which should also improve the poor hot-and-high performance, as those of the previous Mi-8 even behind the Mi-4 and lagged behind many western models. In November 1967 the Central Committee directed the development of the machine, but it was slow because the need for improvement did not appear urgent. The final development phase began in 1971, but was not completed. Only when the Mi-4 was taken out of service did the need for a machine with comparable hot-and-high capabilities increase. An intermediate step was then inserted, which only included the engines, the Ivchenko AI-9W APU installed behind the main gearbox and installed transversely to the flight direction, and the main gearbox of the Mi-14, which was recognizable by the now oval engine outlets. In the summer of 1975 this design was renamed the Mi-8MT, which then had its maiden flight in the form of a conversion from a Mi-8TW Mk.2 on August 17, 1976. Series production of the new version started in 1977 at the Kazan plant. The older Mi-8 models were also produced in Kazan for a long time. Only with the invasion of Soviet troops in Afghanistan and the necessary hot-and-high capabilities of the helicopters used was the number of Mi-8MTs manufactured significantly increased. The helicopter was improved several times in the course of production, so from 1978 the improved TW3-117MT engine was used. The experiences of the Afghan war were also incorporated. The door in the rear gates has been enlarged so that machine guns can also be used for self-defense, dust separators for the engines have been developed and additional internal and external armor for the cockpit has been scaffolded in some versions. In addition, a 7.62 mm PKT machine gun could be installed in the nose and two or four more on the external load stations. On some machines, 12.7 mm NSW machine guns or the 30 mm AGS-17 Plamja grenade launcher were also installed in the side or rear door. In addition, 23 mm UPK-23-250 cannon pods, bombs, rockets and other armament could also be carried at the external load stations. To defend against shoulder-supported anti-aircraft missiles, from 1984 exhaust air mixers could also be installed on the engines and instead of the individual chaff / flare launcher under the tail boom, six pieces on the sides of the fuselage near the engine outlets. An active optoelectronic infrared jammer L-166V-11E was also installed on the sides behind the main rotor. There were also various other changes to improve survivability and reliability and maintainability. From 1986, only versions of the new Mi-8 generation were manufactured in Kazan, with civil machines also being produced from 1983. The designation Mi-17 applies to the export variant of the Mi-8MT, which was first shown at the Paris Air Show in 1981. This designation was only chosen for unarmed export variants.
• Mi-17P / Mi-17S: Passenger version of the Mi-17 for export with a similar layout to the Mi-8P, but with round windows and a large rear door. As Mi-17S, Mi-8S-2, Mi-8MD, Mi-8MS, Mi-8MO and others, a number of VIP versions were also built by the Mi-8MT.
• Mi-8MTW-1 : First version with the repeatedly used designation Mi-8MTW. This was a Mi-8MT as a fire fighting helicopter with attached 2 m³ water tank and space for 20 fire fighters. The Mi-8MTL, presented in 1983, was also used for fire fighting.
• Mi-8MTI / Mi-13 : ECM version of the Mi-8MT with large rectangular antenna housings similar to the Mi-8PP on the sides of the fuselage. The Mi-8MTP , Mi-8MTPB ( HIP-K ) and Mi-8MTSch are also ECM versions, which differ in the attachment of the antennas and the equipment. The similar export versions were called Mi-8PGE for example; Mi-17PG, Mi-17PP and Mi-17TB.
• Mi-18 : Prototype for the second stage of development for the actual Mi-8M. Work on this version began in 1977, and in April 1978 the specifications were officially confirmed and the development contract approved. In the first prototype - converted from a Mi-8MT - the cabin in front of and behind the center of gravity was extended by 25 cm and in section 13 of the fuselage by a further 68 cm, which greatly changed the appearance of the helicopter. The number of seats could be increased to up to 36. In addition, the avionics were completely revised, but the drive (WT3-117MT with 1900 HP take-off power) was taken over unchanged from the Mi-8MT. The prototype started its first test flights in 1979 and was presented to a government commission in 1980. However, it became apparent that the elongated hull could lead to structural problems. Since this would be exacerbated by the additional armor on the cockpit and the additional armament on the rear gate, which was necessary in the Afghan war, this draft was not approved. Instead, a second draft with a modified structure was requested in May 1981. In this case, the insert at the center of gravity was dispensed with, but the insert on section 13 was enlarged to 102 cm, so that the cabin was now 6.34 m × 2.34 m × 1.80 m in size. The resulting change in the center of gravity was compensated for with the additional armor on the cockpit. At the same time, the fuselage structure was completely redesigned, which made it stiffer and less vibrated. A retractable landing gear, other rear doors and a larger tail rotor were also installed and the installation location of the cabin heater was relocated under the fuselage. The maximum take-off weight increased to 13.5 t and the maximum payload to 5 t. The prototype called Mi-18 Mk II (also a conversion from a Mi-8MT) had its maiden flight on April 26, 1984 with test pilots NA Zhen and WT Dworjankin on board. The start of series production was recommended for 1985, but changed goals due to the beginning perestroika led to a delay, so it was not until 1987 that the construction plans (first created with CAD) were handed over to the manufacturing plants. In the meantime, however, the situation in the Soviet Union had changed in such a way that the leadership of the country now demanded helicopters that could also be successful on the world market. This led the manufacturing plant in Kazan to reject the series production of another Mi-8 version and to wait for the introduction of the planned Mi-38 version, which ironically was developed by the development office of the manufacturing plant in Kazan itself on the basis of many construction details of the Mi-18 . Only the two prototypes of the Mi-18 were built, but acceptance tests were never carried out and series production was never started. The second prototype was later heavily modified for special missions.
• Mi-19 : Version as a flying command post, which combines the equipment of the Mi-9 with the drive technology of the Mi-8MT. Mi-19 was produced from 1987. The version Mi-19R is a version of the Mi-19 for the strategic missile forces.
• Mi-8MTKO : Night-flying version of the Mi-8MT, which was shown for the first time on August 15, 1999.
• Mi-8MTW : Version of the Mi-8MT with more powerful TW3-117MT engines for better "hot and high" capabilities and improvements based on the findings of the Afghan war such as cockpit armor, internally foamed tanks, six instead of four chaff / flare launchers, PKT- Machine gun in the nose of the fuselage and other changes for better survivability in combat. The Mi-8MTW-1 was the civilian version of this version with weather radar in the nose. Both versions were built in Kazan from 1998. The Mi-8MTW-2 is an even more heavily armored military version of the MI-8MTW, which also has a weather radar under the nose and modified defense equipment. The Mi-8MTW-3 received the stronger armor and the weather radar of the Mi-8MTW-2, but no PKT machine gun in the nose and only four external load stations. Various derivatives of these versions were also built as VIP transporters, flying cranes (Mi-8MTW-K) and rescue helicopters (e.g. Mi-8MPS = Mi-8MTWMPS for the search for returning space travelers from the Soyuz missions). The Mi-17-1W was an export variant of the Mi-8MTW produced from 1982. The versions of the Mi-8MTW built in Ulan-Ude were given the designation Mi-8AMT , the export versions of which were slightly modified in electronics and equipped with weather radar and marketed as Mi-171 . The machines labeled Mi-171Sch are equipped with TW3-117WM engines.
• Mi-8MTW-5 / Mi-17MD : Version built from 1995 based on the Mi-8MTW-3 with new electronics including new navigation systems, an additional sliding door on the starboard side, a redesigned streamlined bow without a lower cockpit window and a modified stern with a hydraulic one retractable loading ramp. The helicopter had 36 to 40 seats and installation options for four additional tanks with a total of 1660 l in the cabin. From 1997 a version with a modified rear ramp was offered. Export began in 1999, with machines also being built for the Russian army. The variant Mi-8MTW-5-1 also received new radio equipment (KSS-28N-2).
• Mi-172 : The current model designations vary according to the manufacturing plant, engine and others, so that designations such as Mi-171 (e.g. for machines delivered to the Czech Army ) and Mi-172 are used for some machines . The Mi-172 was offered from 1991 by the Kazan plant as a 26-seat passenger helicopter similar to the Mi-8P based on the Mi-8MTW. It received US FAR Pt29 approval in 1994. In 1999 a VIP version was built for the Rwandan President, and in 2003 one for the Russian President Putin. The Mi-172AG received the 2000 hp TW3-117WMA-SB3 engines.
• Mi-17KF Kittiwake: Version based on the Mi-8MTW with western avionics (e.g. Honeywell EDZ-756 glass cockpit). The contract with the Canadian company Kelowna Flighcraft was signed in 1996 and the first prototype took off on its maiden flight in 1997.
• Mi-8MTW-6 , Mi-8MTW-7, Mi-8AMTSch-W: versions with WK-2500 engine (= TW3-117WMA-SB3). In the case of the -7, composite rotor blades were added. The Mi-8AMTSch-W was first spotted in Syria in early 2016 in a version that also carried the L-370E8 Vitebsk self-protection system. This works with four guided missile sensors in the UV range and three infrared jammers. The Mi-8AMTSch-WA was specially developed for use in the Arctic. In addition to improved heating for the cabin, it has heaters for the engine and gearbox, better thermal insulation for the cockpit and cabin, and Teflon hoses for hydraulics and fuel. The avionics have also been revised, which now includes an autopilot, night vision devices and improved navigation devices with redundant GPS receivers.

The following parts of this section seem since 2017 is out of date to be : The year 2017 is over. Has approval been given in the meantime?
Please help to research and insert the missing information .

• Mi-171M / Mi-171A2 / Mi-8AMTSch-2 : Version based on new developments for the Mi-28N and Mi-38. In addition to the avionics, the cargo space was also slightly enlarged and new rotor blades made of composite materials were installed. The Mi-171A2 is the civil version of the helicopter. The prototype OP-1 had its maiden flight in November 2014. The prototype is primarily intended for tests with the new KBO-17 avionics system, which was developed by the instrument development and manufacturing company in Ulyanovsk (part of KRET). It also includes large color screens and allows for a two-man crew instead of the previous three-man crew. The KBO-17 can be supplemented by an enhanced vision system (TV and infrared camera). The engines used are the WK-2500PS-03 from Klimow and a new main rotor with blades made of composite materials and an X-shaped tail rotor (which has already been tested in flight in the test vehicle Mi-171LL). Type certification is expected to be achieved in 2017. The innovations made it possible to improve maneuverability and reduce the overall weight of the rotor system. In addition, travel and top speeds have increased by 20% while increasing the range.
• Mi-8AMTSch-WA : An armed version specially developed for the Russian Navy, based on the Mi-8AMTSch variant, for regions in the Arctic. The helicopter version was developed for particularly low temperatures down to -60 degrees Celsius, with an auxiliary unit, TA-14 from Russian production for the first time, responsible for starting the engines under the low temperatures (before these auxiliary units were imported from Ukrainian production). The helicopter has, among other things, reinforced thermal insulation.
• Mi-17 IFR upgrade version for older and new Mi8 / Mi17 helicopters from the South African company Advanced Technologies and Engineering (ATE) in which, among other things, weight reductions and avionics improvements are carried out. The titanium rotors are being replaced by in-house developments made from composite materials. To this end, the company had signed extensive contracts with Mil, Rosvertol and Kazan Helicopters in 2006, which also include the Mi-2, Mi-24, Mi-26 and Mi-34 model series.
• Mi-8MTPR-1 version for electronic warfare based on a Mi-8MTW-5-1 for electronic tracking of the enemy command post and the use of electronic countermeasures .
• MI-8AMT Arctic version for arctic use. One of the main features of the rotary wing aircraft is a system for heating propulsion components, which is unique according to Russian Helicopters and which was developed by the National Helicopter Center "Mil & Kamow". This system should enable the two Klimow WK-2500PS-03 engines to be started quickly even at extremely low temperatures - even if the helicopter was left outside for a long time. In addition to this, the Mi-8AMT Arctic offers improved thermal protection for the charging cabin and special insulation for the sliding and cockpit doors. To protect against frost damage while standing, Teflon hoses replace the usual rubber counterparts. A special cover protects the helicopter from low temperatures, high humidity and strong winds when it is used for long periods without a hangar. In addition, an extensive navigation system including modern weather radar and digital autopilot was retrofitted. This lets the helicopter "automatically hover, fly a planned hover route and land" if necessary.
