Sub-assemblies of the VK-2500P / PS engines no longer need to be revised at UEC-Klimov.
Technical preparations by United Engine Corporation of the State Corporation Rostec for the manufacture of units and parts for the VK-2500P and VK-2500PS engines designed and manufactured by UEC-Klimov have been completed.
At the end of 2020, the manufacture of key engine units began within the various UEC enterprises - MMP im. V.V. Chernyshev, producing an axial compressor module, and ODK-UMPO, where free turbine modules are assembled. Previously, parts were supplied only for the base engines VK-2500, and for VK-2500P and VK-2500PS, their revision was carried out at UEC-Klimov.
“The use of units and sub-assembly units corresponding to the design of the VK-2500P / PS engines will allow us to reduce labor costs that were previously required for their revision, and to direct resources to solving other production problems, in particular to increase the total output of engines of the VK-family 2500," says the director of production of UEC-Klimov Alexei Rodionov.
In 2021, it is planned to produce more than 70 VK-2500P / PS engines with parts produced by MMP im. V.V. Chernyshev and ODK-UMPO.
The first engine assembled using parts produced in cooperation with the UEC was the VK-2500P engine, which successfully passed state bench tests (GSE) in the autumn of 2020. Then the compliance of the engine components with the established requirements and the possibility of their serial production was confirmed.
The VK-2500P and VK-2500PS engines differ from the basic version primarily by the use of a digital control system of the FADEC type (electronic engine control system with full responsibility). The VK-2500P helicopter engine is the latest modification of the VK-2500 engine, it is installed on many machines of the Mi and Ka families and has improved characteristics. The power plant has a modernised automatic control system and a protective system that restores the normal operation of the engine when it stops, when powder and exhaust gases get in and when surge occurs.
