Mi-8 and Mi-17? The Mi-17 is an improved export version of the Mi-8
helicopter, fitted with more powerful engines and with some other
minor improvements. The Mi-17 is basically an export designation.
Russian military also uses the same helicopter, but it is known as the
Mi-8M. Its Western reporting name is Hip-H.
Mi-8 was phenomenally successful. However it had problems flying in mountainous terrain due to lack of
engine power. It was fitted with 1 400-shp engines. An improved
version was fitted with better Klimov
TV3-117MT engines, developing 1 874 shp each, to produce the Mi-17.
As a result the Mi-17 has better high altitude and overall performance. It was
an important feature for some of its export operators, such as
India. New engines dramatically reduced fuel consumption.
Furthermore the Mi-17 it can limp back home with one of the engines
destroyer or damaged. In the event of failure another engine
automatically increases its power to 2 195 shp. This allows to
continue the flight.
The major visible difference of the Mi-17 is a tail rotor. On
the Mi-17 it was repositioned and is located on the left side, while the original Mi-8
a tail rotor is on the right side. The Mi-17 also has several other
minor improvements, such as new rotor hub made of titanium alloy, different electric grid,
and so on.

During the same year a Russian Mi-8MT was introduced. The first
export Mi-17 was delivered in 1981. This transport helicopter widely exported
both for military and civil operators. The Mi-8/Mi-17 is in service
with more than 70 air arms around the world. It is one of the most
prolific utility helicopters ever built. The Mi-8MT and Mi-8MTV
continue to form the backbone of the Russian army aviation's combat
transport force. The Mi-17 is combat proven, rugged and dependable.

There are dedicated armed versions of this helicopter, that can
carry up to 1 500 kg of weapons externally. These include various anti-tank or air-to-air missiles, bombs, as well as
pods with 57 mm and 80 mm unguided rockets, or even a nose-mounted 20 mm

night vision goggles-compatible cockpit, forward-looking infra-red
