The Ulan-Ude Aviation Plant of the Russian Helicopters holding (part of the Rostec State Corporation) has delivered Mi-171 helicopter with VK-2500-03 engines to a Chinese civil aviation company, said the Holding's press service.
In 2019, the PRC Civil Aviation Administration issued a national type certificate for the Mi-171 helicopter with this power plant. The decision of the PRC aviation authorities expanded the capabilities of the Russian Helicopters holding to meet the needs of the market of this country.
"The key advantages of the helicopter - high thrust-to-weight ratio and operational safety in the mountains - interested potential buyers of helicopter equipment at the end of 2018 during demonstration flights of the Mi-171 in China," said Leonid Belykh, Managing Director of U-UAZ. PRC Civil Aviation Administration and the leadership of the Ministry of Emergency Situations then highly appreciated the capabilities of the helicopter for the transportation of goods on an external sling, emergency response, as well as for the operational loading and unloading of rescuers and firefighters. "
The VK-2500-03 engine, developed and supplied by the UEC-Klimov enterprise, is more powerful that the older TV3-117VM engine series 02, especially when used in high altitude due to its heat-resistant materials and improved design. The introduction of the BARK-78 digital automatic control system gives more detailed control over the engines and their different modes, and generally simplifies their operation. The use of VK-2500-03 engines in Mi-171 helicopters ensures higher load capacity and increases the operational and hovering ceiling. Besides, greater available engine power in an emergency mode ensures greater safety during the flight with one running engine.
This was already a second Chinese civilian airline to buy helicopters of this configuration. China currently operates a total of about 200 Mi-171 helicopters.
