Russian state-owned company, United Engine Corporation (part of Rostec State Corporation), is bringing its latest civil turboshaft helicopter engine, the VK-2500PS-03, to Vietnam, Cambodia, Thailand and Malaysia, the company said in a press statement.
Two engines of this type are part of the Mi-171A2 helicopter's power unit and are being touted to potential customers during a demonstration tour of several countries of Southeast Asia.
The 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 engine failure and to make Mi-17 helicopters more functional when operating in highlands and hot climate.
The demonstration tour stretches over almost 5,000 kilometres and includes demonstration flights, as well as events for partners and potential operators 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 the company’s Aleksander Vatagin. “The presence of the FADEC-type digital control system is the main structural difference of the VK-2500PS-03. The time between overhauls is twice as long as that of its predecessors. To date, the engine has been certified by aviation authorities of Russia and the work on its validation in China is under way.”
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 the VK-2500PS-03. Technical solutions used in the VK-2500PS-03 by UEC-Klimov's engineers allow users 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 per cent, and carrying capacity by 25 per cent.
