The Mil Mi-8 (NATO reporting name "Hip") is a large twin-turbine transport helicopter that can also act as a gunship. The first single-engine (AI-24W) prototype, W-8, flew in 9 July 1961. A second one with two AI-24W engines made its first flight on 17 September 1962. After few changes it was introduced into the Soviet Air Force by 1967 as Mi-8. There are numerous variants, including the Mi-8T which in addition to carrying twenty four soldiers is also armed with rockets and anti-tank guided missiles. The navalized Mil Mi-14, and attack Mi-24 are derived from the Mi-8.

The Mi-8 is used by over 50 countries, including India, China and Iran; the latest variant, known as the Mi-8MT/Mi-17 is more heavily armed and was introduced in 1981. The Mi-17 is less widely used, employed by around 20 countries.

[edit] Mi-17

The Mil Mi-17 (Also known as the Mi-8MT, NATO reporting name Hip-H) was developed from the basic Mi-8 airframe it was fitted with the larger TV3-117MT engines, rotors, and transmission developed for the Mi-14, along with fuselage improvements for heavier loads. Optional engines for 'hot and high' conditions are the 1545kW (2070 shp) Isotov TV3-117VM. Recent exports to China and Venezuela for use in high mountains have the new VK-2500 version of the engine with FADEC control.

The designation Mi-17 is for export; the USSR armed forces call it Mi-8MT. The Mi-17 can be recognized because it has the tail rotor on the port side instead of the starboard side, and dust shields in front of the engine intakes. Engine cowls are shorter than on the TV2 powered Mi-8, not extending as far over the cockpit, and an opening for bleed-valve outlet is present forward of the exhaust.

Actual model numbers vary by builder, engine type, and other options. As an example, the sixteen new Ulan Ude built machines delivered to the Czech air force in 2005 with –VM model engines were designated as Mi-171Sh, a development of the Mi-8AMTSh. Modifications include a new large door on the right side, improved Czech-built APU, Kevlar plates around the cockpit area and engines. Eight have a loading ramp in place of the usual clamshell doors, and will load a vehicle up to the size of an SUV.

The Mi-17 is also used for search and rescue team like Malaysian Fire and Rescue Department in Malaysia.

[edit] Prototypes/experimental/low production variants

  • V-8 (NATO: Hip-A) - The original single-engined prototype.
  • Mi-8 (NATO: Hip-B) - Twin-engined prototype.
  • Mi-8TG - Conversion to operate on LPG gas.
  • Mi-18 - Prototype helicopter design, a modification of the existing Mil Mi-8. Two Mi-8s were extended by 0.9 meters (3 ft), the landing gear made retractable, and a sliding door added to the starboard side of the fuselage. The Mi-18s were trialed in the Soviet invasion of Afghanistan, and later used as static training airframes for pilots of the Mi-8/17.

[edit] Basic military transport / airframe variants

  • Mi-8T (NATO: Hip-C) - First mass production utility transport version, can carry unguided rocked pods (with S-5 rockets) and side mounted PK machine gun.
  • Mi-8TVK (NATO: Hip-E) - used as a gunship or direct air support platform. Airframe modifications add 2x external hard points for a total of 6, and mount a flexible 12.7 mm machine gun in the nose. Armament of 57 mm S-5 rockets, bombs, or AT-2/SWATTER ATGMs.
  • Mi-8AMTSh (for export: Mi-171Sh) - Variant with new large door on the right side, Kevlar plates around the cockpit area and engines. Some of them (but not all) have a loading ramp in place of the usual clamshell doors, and will load a vehicle up to the size of an SUV.

[edit] Command and electronic warfare variants
