Mil Mi-8M / Mi-17 / Mi-19 / Mi-171 / Mi-172



First identified in 1980-81, the Mi-17 is virtually a revision of the Mi-8 design using a combination of the 'Hip' airframe but with the port-side tail rotor, and fitted with the more powerful powerplants of the Mi-14. A new rotor hub of titanium alloy was developed for the Mi-17. These result in an overall improvement in performance, particularly the hovering ceiling. The Mi-17 retains the codename 'Hip-H'.

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. For operation in 'hot and high' conditions, Kazan commercial versions can be supplied with TV3-117MT engines and tail rotor with wider-chord blades. 



Mil Mi-17

The basic Mi-17 is powered by two 1,434kW (1,923 shp) Klimov TV3-117MT turboshafts. Should one engine stop, output of the other increases automatically to contingency rating of 1,637kW (2,195 shp), enabling flight to continue. An APU for pneumatic engine starting is provided,and deflectors on engine air intakes prevent ingestion of sand, dust and foreign objects. Single flexible internal fuel tank, capacity 445 litres; two external tanks, each side of cabin, capacity 745 litres in port tank, 680 litres in starboard tank; total standard fuel capacity 1,870 litres. Provision for one or two ferry tanks in cabin, raising maximum total capacity to 3,700 litres.
Configuration and payloads generally as Mi-8 but six additional centreline seats optional. Military Mi-17-1V carries up to 30 troops or 20 wounded troops in ambulance configuration. Civilian Mi-17 promoted as essentially a cargo-carrying helicopter, with secondary passenger transport role.

Mi-17V/171 systems include AI-9V APU for pneumatic engine starting, and AC electrical supply from two 40kW three-phase 115/220V 400Hz GT40/P-48V generators. Avionics include Baklan-20 and Yadro-1G1 com radio and Type 8A-813 weather radar. Optional are ASO-2 chaff/flare dispenser under tailboom and IR jammer (NATO 'Hot Brick') at forward end of tailboom.

Equipment and armament options are as for the Mi-8, plus, on military versions, external cockpit armour; engine nozzle IR suppressors and a VMR-2 fit for air-dropping, 23mm GSh-23 gun packs, AAMs and newer ASMs on Mi-8AMTSh.

Revealed to the world at the 1981 Paris air show, the Mi-17 is known by the Russian military as the Mi-8M. Export customers and Russian civilian operators use the Mi-17 designation.

Entered service with Soviet forces in 1977 as Mi-8MT. The first export examples were delivered to Cuba in 1983, and Mi-17s were in service in Angola, Hungary, India, North Korea, Nicaragua, Papua New Guinea, Peru and Poland, as well as the CIS.


Mi-8 derivatives include Mi-17 (first flown August 1975) with change of engines and other modifications and Mi-171/Mi-172 export models, and lengthened Mi-173. Individual factories continue to develop new Mi-17 variants, like the Mi-171 produced by the Ulan Ude factory. Production of Mi-17M/V and Mi-172 for both civil and military use as a cargo-carrying helicopter, with secondary capability as a passenger transport capable of carrying up to 24 passengers, or 12 stretcher cases when used as an ambulace was at Kazan and Mi-171 at Ulan-Ude plants, from where they are marketed. More than 810 exported by Aviaexport. Production of both the Mi-8 and Mi-17 continued in 1987.

Long-range modification: AEFT (Auxiliary External Fuel Tanks) system by Aeroton adds a further 1,900 litres in two internal tanks, plus 2,850 litres 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 1,300km; ferry range 1,850km.
