The Mil Mi-17 (also known as the Mi-8M series in Russian service, NATO reporting name "Hip") is a Russian-designed helicopter currently in production at two factories in Kazan and Ulan-Ude. Mil Mi-8/17 is a medium twin-turbine transport helicopter that can also act as a gunship.

[edit] Development

Developed from the basic Mi-8 airframe, the Mi-17 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 1545 kW (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; Russian 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 armor 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.

In October 2007 defense-aerospace.com reported the government of Saudi Arabia had signed a contract for up to 150 Mi-35 and Mi-17 helicopters worth $2.2billion.^[2]

In May 2008, licensed production of the Mi-17 started in China with production being led by Mil Moscow Helicopter Plant JSC and the Sichuan Lantian Helicopter Company Limited in Chengdu, Sichuan province. The plant had built 20 helicopters in 2008, using Russian Ulan-Ude-supplied kits. The production is expected to reach 80 helicopters per year eventually. The variants to be built by Lantian will include Mi-171, Mi-17V5, and Mi-17V7^[3].

On 28 October 2008, the Royal Thai Army announced a deal to buy 6 Mi-17 to meet its requirement of a medium-lift helicopter, marking the first time the Thai military will acquire Russian aircraft instead of American.^[4] Flight International quotes the Thai army’s rationale: “We are buying three Mi-17 helicopters for the price of one Black Hawk. The Mi-17 can also carry more than 30 troops, while the Black Hawk could carry only 13 soldiers. These were the key factors behind the decision.” ^[5]

On 15 December 2008, Defense News reported that India will purchase 80 Mi-17IV helicopters which will be delivered to Indian Air Force between 2010 and 2014. These will replace aging Mi-8s.

On June 11, 2009, it was announced that the United States handed over four MI-17 cargo helicopters to the Pakistan Army to facilitate its counter-terrorism operation.

On July 10, 2009. It was announced that Chile will push talks with Russia to purchase five Mi-17 multirole helicopters for the Chilean Air Force despite pressure from the United States.^[6]
