JSC Klimov began work on creating engine VK-800V

The past year has been to St. Petersburg Engine Building Company "JSC" Klimov "", a subsidiary of the United Engine Corporation, a breakthrough in many ways: a full-scale work on a new long-term helicopter engine. On what conceptual and technical solutions will have this, like, a breakthrough product, as well as work on other helicopter powerplants Show Observer in an interview said chief designer of "Klimov" — Deputy General Designer of the United Engine Corporation for helicopter engines Alexei Grigoriev.

Alexey, like any industry exhibition, HeliRussia is an indicator of the state of the market. What would you have summed up the year with the conduct HeliRussia 2012, what was achieved and what plans will be implemented this year?
— The main achievement of the past year — is that of "Klimov" launched a full-scale efforts to establish long-term helicopter engine (LDPE). This was preceded by serious preparation stage, when our company together with sector institutions, in particular with The Central Institute of Aviation Motors, conducted a search of scientific-research work and defined the contours of a future program. Just note that the program we are going to follow the path of the use of breakthrough innovative solutions, including changing the cornerstone for a gas turbine engine — the Brayton cycle. I am convinced that the time has come to present to the market is really a breakthrough product that has not only technical but also conceptual differences from existing engines. At this year’s scheduled practical implementation of several elements of the future engine.

— How to prepare for certification moves TV7-117V? What are the stages already passed the test? When do you plan to complete the certification and what period of time laid on fine-tuning the engine?
— To date, completed the stage of life test bench engine. This year we plan to complete the preliminary tests, including flight design, and proceed with the certification of the engine. Currently, the testings involved more than 10 engines TV7-117V, including flight models.
According to test results we see no serious issues that could affect the schedule, so we expect certification of the power plant in 2014, As for finishing the engine, it is a continuous process that accompanies the engine throughout its entire life cycle, including during the period of actual operation.

— How is the program to improve engine VK-2500? Are the stated specifications VC-2500PS on the parameters that were identified during the test?
— As a small deviation would like to say that the operation of the base engine, the VK-2500, continuing successfully. Now on the wing more than 700 engines, and their total time exceeded 500 thousand hours Modernization of this model comes in two ways: VC-2500P for helicopters Mi-28 and Ka-52 and the civilian version of the powerplant VC-2500PS for Mi- 17A2. In fact it is the same engine, but at the same state tests will be conducted for the Ministry of Defence with the necessary amount of spetsispytany, while the second will be a full-sized certified civil norms. Currently, an important stage of life tests, the conclusion has already been received at the beginning of flight tests, to which we, together with JSC "Helicopters of Russia" will begin in the near future. The test results confirmed all the declared technical characteristics of the new engine modifications, and by the end of the year is planned for public presentation engine bench testing and the start of certification work.

— Promising engine VC-800B — the only project power plant is being developed now a "clean slate." How’s this project?
— Promote the project in Russia is hampered by lack of real helicopter on which the VC-800B engine could be installed. Traditionally in Russia are the objects in the class take-off weight of 10-12 tons Helicopters mass 4 — 5 m for which designed and VK-800V, and have remained on paper. In view of the characteristics of the engine competitive on the western and eastern markets, where the spread helicopters of this class, but these markets are fairly rigidly reserved. However, as we are confident in the prospects of the project, now VC-800B engine is used in the framework of the program of establishing the planned helicopter engine for developing key technologies in various fields, such as thermodynamics, gas dynamics, and materials science. A number of promising technologies will be implemented in the final version of the engine, which is scheduled for certification in 2016
