Everything about Mi-17 totally explained
The
Mil Mi-17 (also known as the
Mi-8M series in Russian service), is a Russian-designed
helicopter currently in production at two factories in
Kazan and
Ulan-Ude.
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 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; 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 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.
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.
A licensed production of the Mi-17 will start in China with production being led by Mil Moscow Helicopter Plant JSC and the Sichuan Lantian Helicopter Co. Ltd. in Chengdu, Sichuan province.
