Mi-8 multi-mission helicopter
Mi-8 multi-mission helicopter(NATO code HIP) is manufactured by the Mil Moscow Helicopter Plant JSC in Moscow and the Kazan Helicopter Plant JSC in Kazan and are available in civil and military versions. . More than 12,000 Mi-8 (NATO codename Hip) multi-purpose helicopters have been produced, as well as more than 2,800 exported to over 50 air forces. Mi-8 family is the world's most produced helicopter design including high level development project Mi-14 and Mi-17.
The Mi-8 is a roomy twin-turbine helicopter, with a five-bladed main rotor. The production began in 1964 for both military and civil variations. The Mi-8 military variants include the Mi-8T transport, VIP transport, electronic warfare, reconnaissance, Mi-8TV armed version and the search and rescue Mi-8MPS.
April 2011, MOSCOW — Moscow and Washington have agreed the terms of a contract to supply Afghanistan with 21 MI-17 helicopters, Kommersant daily said on Wednesday, adding Russia would pocket $367.5 million as a result of the deal. Citing Germany's special representative on Afghanistan and Pakistan Michael Steiner and Afghanistan's Air Force Chief of Staff Abdul Wahab Wardak, the business daily said the countries had agreed the deal which had been the subject of talks between NATO and Moscow for over a year. "As the Americans told me, the contract is about to be signed," the Afghan general told Kommersant. "We expect the aircraft will begin being delivered already at the end of the year -- we very much need it," he said, adding that the price of one helicopter stood at $17.5 million. Washington has decided to pick up the tab after months of talks between NATO and Russian officials ground to a halt. Some NATO states pressed Russia to deliver some of the helicopters for free as they were unable to pay Russia for the aircraft. Citing sources close to the Russian defence ministry, Kommersant said the firm deal had not yet been signed but its price tag would include cost of repair, spare parts and pilot training.
The Mi-8T transport helicopter for the USSR military forces is configured with a conventional pod and non-retractable tricycle nosewheel landing gear. The five-bladed rotor is made from aluminium alloy. The 3 person crew are commander, navigator and flight mechanic. The cockpit and the main cabin are heated and air conditioning is optional, with an oxygen system in the ambulance and rescue variants.
For surviving in battle field, the Mi-8s are equiped with crew cabin armour plating, explosive resistant foam filling in the fuel tanks, a fire-fighting system and duplicated and stand-by hydraulic and power systems and main control circuits. And de-icing systems are added.
The Mi-8's landing-transport equipment can be used to load light towed combat material and armament via winches. It can also rescue people from the ground or from the sea by an electrically operated hoist with 200 kg capacity.
On the cabin floor there are cargo tiedown points. Ramps are provided for loading vehicles in the big back door. The cabin can accommodate 12 stretchers. And the external cargo sling is rated to carry 3,000 kg.
The Mi-8T helicopter is powered by two Klimov TV2-117 turboshafts engines. Deflectors are installed on the engine air intakes to prevent ingestion of dust so that Mi-8 is suitable for unprepared pads. And an auxiliary power unit (APU) is designed for self-contained operations.
The Mi-8 can carry 1,870 litres of fuel in two flexible internal tanks and two external tanks. Adding two ferry tanks in the cabin, the total fuel capacity can be increased to 3,700 litres. But the space for cargo is limited in this way.
The MI-8TV armed variant is designated from Mi-8T, fitted with 7.62mm built-in machine guns and six external weapons racks with S-5 rockets. The helicopter can also deploy AT-2 Swatter 9M-17P Skorpion anti-tank missiles. The helicopter's weapon sighting system is the PKV collimating sight. Mi-8TV can also be used to make minefields.
The Mi-8TV helicopters are fitted with more powerful TV3-117VMA engines which gives an improved hovering ceiling (3,950 m compared to the 1,760 m of the Mi-8MT). The maximum slung payload of the armed helicopter is increased to 4,000 kg. A Hot Brick infrared jammer can be fitted and six ASO-2V flare dispensers are installed, three to the port and three to the starboard side of the fuselage.
The Mi-8MPS search and rescue helicopter was developed from the military transport variation. In rescue missions, the helicopter crew drop radio-beacons to mark the distress area and deliver rescue teams to aid and recover the casualties. The helicopter can lift ten people at a time on a sling via a PSN-10 life raft and is provided with an emergency landing device that ensures buoyancy for up to 30 minutes.
Mi-8AMTSh is an army, modernized, transport and assoult chopper. It is euiped with automatic cannon, aerial rockets, 8 anti-tank missiles "Ataka" ("Shturm" complex).
The Mi-8MPS incorporates specific modifications, including a larger entrance door, two starboard hatches, a raft container and external additional fuel tanks. Other equipment includes PNKV-8PS pilot/navigation system, YuR-40.1 radar system, TAPAS thermal search and rescue equipment, an airborne jib with LPG-300 winch and scoop. For spacecraft recovery, the Mi-28MPS helicopter delivers operational and technical groups with rescue equipment to the landing zone. Instrument and visual search methods are used to locate spacecraft returning the landing zones. The MPS will recover the cosmonaut and return him to base. Up to 3,000 kg cargo can be transported by sling.

Mi-8 Salon - VIP version
Mi-14(Photo) is a navalized floating version, it contains several sub-variations:
Mi-14BT - base combat version.
Mi-17, entered service in 1975, is the highly improved Mi-8, with more powerful engines for 'hot and high' conditions. NATO calls it "HIP H". The USSR armed forces called it Mi-8MT. It first showed off in Paris Airshow in 1981, and exported to Cuba in 1983. In fact many Mi-8MT in USSR forces are not brand new but converted from fommer Mi-8s. Such as the Mi-8 eletronic countermine version is developed into Mi-17P.
The Mi-17 can be recognized because it has the tail rotor at the starboard side, instead of the port side. Two 2250hp Isotov TV3-117VM engines. Sub-variations of Mi-17 are:
Mi-17 Airbone Medical Variation
In 1990`s, Kazan Plant began to turned to build the advanced products of Mil, such as Mi-38. The production of Mi-17 was handed to those company in far-east. And Mil upgraded the design of the power plant, eletronic equipments and reliability of the Mi-17. the new Mi-17 is called Mi-171, which begun to be built in 1991. Some Mi-171 is also called Mi-8AMT.Mar 2002, the Malasiya army imported 10 Mi-171 for US$ 50 million.
China imported Mi-8s since 1970`s, Mi-17s and Mi-171s later for military forces and civlian cargo transportation. The following photos presents Mi-17s in China.
The Mi-17MD (Russian market designation ¨C Mi-8MTV5) multipurpose helicopter is a further development of the Mi-17 helicopter well-known throughout the world. Flight and technical characteristics and power-to-weight ratio of the helicopter are considerably enhanced due to employment of the new TV3-117VM engines that enable it to fly at altitudes up to 6,000 m, achieve a level flight speed of 270 km/h and acquire a climb rate of up to 20 m/s. The Mi-17MD is intended for airlifting of troop units to areas of combat action. While performing the shuttle flights, several Mi-17MDs can carry out heliborne operations to deliver several hundred airlanding troopers or infantrymen to an assigned area in the enemy's deep rear, providing them with air cover by means of onboard armament. A loading/unloading ramp and two sliding doors of the cargo cabin make it possible to perform embarkation/debarkation of 35 troopers in just 15 to 20 s.The crew cabin lighting equipment allows the pilots to use night vision goggles that considerably extend the flight capabilities during dark conditions, improve search conditions of ground objects and victims, and enable the crew to fly special missions at night and perform low-altitude flights. Upgraded armor for the crew cabin and vital systems protects the helicopter against small arms, while onboard chaff dispensers defend it against ground-to-air heat-homing missiles. The modernized fuel system enables the helicopter to fly a ferry range of up to 1,600 km and perform patrolling of the assigned area or searches for people in distress lasting 10 to 12 hours. The Mi-17MD can be used in several versions. Troop-carrying version. The helicopter is capable of airlifting up to 35 fully armed troopers in the cargo cabin. An enlarged port-side sliding door, as well as a starboard sliding door and a remotely extended loading ramp outfitted with a hydraulic drive enable the heli-borne troopers to embark/debark in a matter of seconds after landing. A training airlanding heliborne system provides for leaving the helicopter in air through two doors and opening of the removed loading ramp. The helicopter's design enables the trooper parties (up to four troopers at a time) to leave the helicopter by means of SU-R cable-type landing facilities while the helicopter hovering at a height of up to 30 m above the ground.
