Moon engine completes inter-agency testing

Samara. April 25, 2012  Last Friday the NK-33A engine completed the cycle of inter-agency testing (IAT).

On April 20 at the No. 1 stand of the separate subdivision Vintai, the NK-33A engine completed the fourth and final hot-fire test under the IAT program. The engine worked for 157.5 seconds unconditionally. The total working time over four launches was 600 seconds.

Further the NK-33A engine will undergo a cycle of cleaning; it will be disassembled, reinspected, and presented tomembers of the inter-agency committee to make a final decision on the results of the tests. Passing the April launches of the NK-33A is an important step in fulfilling the Soyuz-2-1v work using the capacity of the NK-33 engine and expanding production of the new NK-33A for the Russian space program, as well as for potential foreign clients.

Within one and a half months the inter-agency committee will make its decision about whether to allow production of the NK-33A, as well as for flight tests. But already today we can speak of positive results: the engine has demonstrated itself very well in tests in different conditions and with its designed capacity, said the chief designer of Kuznetsov, Valery Danilchenko.

The NK-33A engine is a version of the NK-33, which was developed at the Nikolai Kuznetsov design bureau 40 years ago for the Soviet Lunar Program. State testing of new technology at Kuznetsov has not taken place within the last 25 years.

Kuznetsov is one of the largest companies in aviation and space engine building. The companys engines are used to launch the manned space vessels Vostok, Voskhod, and Soyuz, and the unmanned freight transport space vessel Progress. The company is one of the main producers of engines for domestic strategic aviation, gas transportation stations, and steam power plants. It is part of the United Engine Corporation.

United Engine Corporation is a wholly-owned subsidiary of OBORONPROM specializing in engine-building assets.

OBORONPROM is a multi-faceted machine-building group of companies, founded in 2002. It is part of the Russian Technologies group of companies. Its primary activities are helicopter building (Russian Helicopters), engine-building (UEC), and other assets.
