Mil Mi-28

The Klimov VK-2500 is a Russian turboshaft aero engine, a high power derivative of the TV3-117VMA engine, also for hot and high.[1]

Design

[edit]

It differs from the older versions in having an extended overhaul period of the engine hot components, extra gas-dynamic stability at varying duties, engine parameters accuracy and engine control quality, enhanced monitoring depth providing operation of the engine according to its technical condition and better weight characteristics and overall dimensions.
