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.
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.
