Crews of the light Mi-34M1 helicopter now interact with the new-generation powerplant directly through a digital interface in the cockpit. The VK-650V turboshaft engine, developed by the United Engine Corporation (part of the Rostec State Corporation), represents one of the most advanced "digital" platforms in the domestic aircraft industry.
According to Rostec representatives, the VK-650V was initially designed as a unified cyber-physical system, in which mechanical components and control software were developed in parallel rather than sequentially. Unlike traditional approaches, where electronics are added to an already finished "hardware" platform, the new engine has been fully modeled in a digital environment: calculations cover loads, thermal conditions, component wear, and the unit's behavior under all operating conditions.
This approach significantly reduces the pilot's cognitive load: the electronic system automatically regulates fuel supply, optimizes fuel consumption, and provides multi-level protection against overloads and critical modes. In addition, the engine is equipped with an integrated monitoring system that continuously collects telemetry on the unit's condition. This makes it possible to shift from scheduled maintenance to predictive maintenance — repairs and replacements are carried out based on the actual condition of components, which improves flight safety and reduces equipment downtime.
The VK-650V became the first domestic turboshaft engine intended for light helicopters with a takeoff weight of up to 4 tons. The unit demonstrates increased takeoff power, improved specific characteristics, and is capable of developing up to 750 hp in emergency mode.
