Specialists at UEC-Saturn (part of the United Engine Corporation, Rostec Group) have developed and implemented innovative technologies to ensure the start of serial production of key components for the advanced VK-650V helicopter engine.
The VK-650V is a compact engine, so the small size of the parts presents a particular challenge in manufacturing, and even minimal deviations during machining can affect the accuracy of the geometry.
As part of the modernization of the machine park, advanced CNC machines were installed at the enterprise, which made it possible to bring most of the production operations to a new level. The developed exclusive control programs for this equipment have already passed rigorous certification and have proven their effectiveness, meeting the highest industry requirements. Specialized tooling designed for precision machining of small parts is used for the manufacture of VK-650V components.
One of the main components that UEC-Saturn manufactures and assembles is the gearbox. It transmits torque from the engine to the main rotor and auxiliary units. The unit consists of many high-tech parts, including gears, bearing housings, and elements of the engine oil system.
In addition, the company produces the first support housing for the VK-650V. It is made from a solid cast blank, the processing of which takes eight to nine weeks and includes several hundred operations. They are mainly performed on CNC vertical turning lathes and using five-axis machining centers. The quality of the first support housing directly affects the operation of the compressor, as it ensures uniform distribution of the incoming air flow.
