VK-2500

VK-2500
Basic information

The new VK-2500 turboshaft engine is designed for upgrading medium-load helicopters such as Mi-8MT/Mi-17, Mi-24, Mi-14, Ka32, Ka-50, Mi-28 and others.
The VK-2500 is based on the TV3-117 engine family. Compared to its predecessor, the basic TV3-117VMA engine, it features a 15-20% higher power, a new full authority digital control system (FADEC) and a longer service life. In 2001-2001 the engine passed certification by the Interstate Aviation Committee Aviation Register (certificate No. ST197-AMD) and government bench tests. The existing helicopter fleet may be easily upgraded with this engine due its full compatibility with the previous versions.

Principal specifications

PRODUCT QUALITY

Excellent capabilities

Thanks to the improved performance of the VK-2500 engine the helicopter ceiling increases by 30%, the rate of climb by 50% and the payload, depending on the helicopter model, by 1,000 – 2,000 kg. The engine also improves the speed and maneuverability of the helicopter. Accordingly, the aircraft gain fundamentally new qualities for operation in the mountains as well as in areas with a hot climate.

Improved Safety

Should one of he engines fail, the flight safety is greatly enhanced owing to the emergency power feature (2700 hp) of the VK-2500 engine.

Flexible power options and trouble-free maintenance

The engine can be adjusted to use any of the  three horsepower options available depending on the customer’s preference.    This choice helps take full advantage of the helicopter’s features as well as save fuel.

SERVICE AND SUPPORT

The Klimov Company provides a full range of support services including the overhaul of VK-2500 engines. In fact, TV3-117 engines delivered for repair or overhaul may be upgraded to VK-2500 for a drastic improvement in helicopter performance.
