HANOI,
VIETNAM - EQS�-
November 26, 2018 -�Customers from Southeast Asia
will have the opportunity to learn about capabilities of the latest Russian
civil turboshaft engine VK-2500PS-03 developed and manufactured by United
Engine Corporation (part of Rostec State Corporation). Two engines of this type
are part of the Mi-171A2 helicopter's power unit. The helicopter participates
in Russian Helicopters Holding Company's demonstration tour of several
countries of Southeast Asia -- Vietnam, Cambodia, Thailand, and Malaysia.

VK-2500PS-03 is the latest
modification of the VK-2500 engine with improved performance characteristics. It uses the most advanced FADEC-type digital electronic
management and control system. The anti-surge control is implemented to
eliminate the possibility of the engine failure and to make Mi-17 helicopters
more functional when operating in highlands and hot climate.

The demonstration tour of
the countries of Southeast Asia, in which the Mi-171A2 takes part, has the
route of almost 5 thousand km long, and it passes through Vietnam, Cambodia,
Thailand, and Malaysia. It includes demonstration
flights, as well as events for partners and potential operators organized to
present key benefits of Russian helicopters and after-sales service.

"This engine continues the well-known
series of TV3-117 engines and is its in-depth modernization, -- said Aleksander
Vatagin. -- The presence of the FADEC-type
digital control system is the main structural difference of VK-2500PS-03. The time between overhauls is twice as long as that of
its predecessors. To date, the engine is certified by aviation authorities of
Russia and the work on its validation in China is under way."

During overhaul TV3-117
and VK-2500 engines can be refitted into the latest VK-2500PS-03.

The opportunity to control engine
life depending on specific operating conditions instead of the previous
approach to the life service estimation is of crucial importance for operators
of VK-2500PS-03. Technical solutions used in VK-2500PS-03 by UEC-Klimov's
engineers allow to accurately determine the real state of the engine, which in
turn eliminates the human factor.

Mi-171A2 is the latest
modification of Mi-8/17/171 helicopters. Indicators of cruising and maximum
speed of Mi-171A2 in relation to serially produced Mi-8/17 helicopters are increased
by 10%, and carrying capacity -- by 25%.
