Hip-H and K derivative


Prototype, known initially as Mi-18, completed 1975 with basic Mi-8 airframe, and power plant and dynamic components of Mi-14. Entered service with former Soviet forces in 1977 as Mi-8MT. First displayed at 1981 Paris Air Show as Mi-17 for civil use and export; exports began (to Cuba) 1983; production of improved versions continues at Kazan and Ulan-Ude plants, from where they are being developed and marketed (see these entries for addresses).


Basic designation of series, with suffix M for military versions. Mi-17P is basic civil version with 28 seats and rectangular cabin windows. All versions in Russian Federation and Associated States military service retain Mi-8 designations. Detailed description applies to basic versions, except where indicated.

  • Mi-17MD: Described under Kazan heading in this section.
  • Mi-17KF: Described under Kazan heading in this section.
  • Mi-19: See separate entry.
  • M-17 Z-II: Converted from `Hip-H' in former Czechoslovakia for

    electronic warfare role; local designation (Z-I is similarly tasked Antonov An-26). First seen in Czech Air Force service at Dobrany-Line air base, near Plzen, 1991; each of two examples had a tandem pair of large cylindrical containers mounted each side of cabin; assumed that containers made of dielectric material and contain receivers to locate, analyse and jam hostile electronic emissions; each of two operator's stations in main cabin has large screens, computer-type keyboards and oscilloscope; several blade antennae project from tailboom. Currently in service with Slovak Air Force. Long-range modification: AEFT (Auxiliary External Fuel Tanks) system by Aeroton adds a further 1,900 litres (502 US gallons; 418 Imp gallons) in two internal tanks, plus 2,850 litres (753 US gallons; 626 Imp gallons) in six tanks on the stores pylons of Mi-8MT, AMT, MTV-1, civil MTV and Mi-17 variants. Operational range with all eight auxiliary tanks is 701 n miles (1,300 km; 807 miles); ferry range 998 n miles (1,850 km; 1,149 miles). Users include Leningrad customs service.

    CUSTOMERS: Many operational side by side with Mi-8s in RFAS armed forces; also operated in Afghanistan, Angola, Bangladesh, Bulgaria, Burkina Faso, Cambodia, China, Costa Rica, Croatia, Cuba, Czech Republic, Ethiopia, Hungary, India, North Korea, Nicaragua, Pakistan, Papua New Guinea, Peru, Poland, Romania, Sierra Leone, Slovak Republic, Sri Lanka, Syria, Turkey, Venezuela, Vietnam, Yugoslavia. More than 810 exported by Aviaexport.

    DESIGN FEATURES: Distinguished from basic Mi-8 by port-side tail rotor; shorter engine nacelles, with air intakes extending forward only to mid-point of door on port side at front of cabin; small orifice each side forward of jetpipe; correct rotor speed maintained automatically by system that also synchronises output of the two engines.

    POWER PLANT (basic Mi-17): Two 1,397 kW (1,874 shp) Klimov TV3-117MT turboshafts; should one engine stop, output of the other increased automatically to contingency rating of 1,637 kW (2,195 shp), enabling flight to continue; deflectors on engine air intakes prevent ingestion of sand, dust and foreign objects.

    ACCOMMODATION: Configuration and payloads generally as Mi-8; but six additional centreline seats optional. Military Mi-17-1V carries up to 30 troops, up to 20 wounded in ambulance role, or weapons on six outrigger pylons; civilian Mi-17 promoted as essentially a cargo-carrying helicopter, with secondary passenger transport role.

    SYSTEMS (Mi-17-1V/171): AI-9V APU for pneumatic engine starting; AC electrical supply from two 40 kW three-phase 115/220 V 400 Hz GT40/P-48 V generators.
