Kuznetsov Design Bureau


The Kuznetsov Design Bureau was a Russian design bureau for aircraft engines, administrated in Soviet times by Nikolai Dmitriyevich Kuznetsov. It was also known as GNPO Trud and Kuybyshev Engine Design Bureau.
NPO Trud was replaced in 1994 by a Joint Stock Company, Kuznetsov R & E C.
By the early 2000s the lack of funding caused by the poor economic situation in Russia had brought Kuznetsov on the verge of bankruptcy. In 2009 the Russian government decided to consolidate a number of engine-making companies in the Samara region under a new legal entity. This was named JSC Kuznetsov, after the design bureau.

Products

The Kuznetzov Bureau first became notable for producing the monstrous Kuznetsov NK-12 turboprop engine that powered the Tupolev Tu-95 bomber beginning in 1952 as a development of the Junkers 0022 engine. The new engine eventually generated about 15,000 horsepower and it was also used in the large Antonov An-22 Soviet Air Force transport.
Kuznetsov also produced the Kuznetsov NK-8 turbofan engine in the class that powered the Ilyushin Il-62 and Tupolev Tu-154 airliners. This engine was next upgraded to become the about Kuznetsov NK-86 engine that powered the Ilyushin Il-86 aircraft. This Bureau also produced the Kuznetsov NK-144 afterburning turbofan engine. This engine powered the early models of the Tupolev Tu-144 SST.
The Kuznetsov Design Bureau also produced the Kuznetsov NK-87 turbofan engine that was used on the Lun-class ekranoplan.
Kuznetsov's most powerful aviation engine is the Kuznetsov NK-321 that propels the Tupolev Tu-160 bomber and was formerly used in the later models of the Tu-144 supersonic transport. The NK-321 produced a maximum of about of thrust.

Kuznetsov also produced the Kuznetsov NK-8 turbofan engine in the 20,000-pound-thrust class that powered the Ilyushin Il-62 and Tupolev Tu-154 airliners. This engine was next upgraded to become the about 28,000-pound Kuznetsov NK-86 engine that powered the Ilyushin Il-86 aircraft. This Bureau also produced the Kuznetsov NK-144 afterburning turbofan engine. This engine powered the early models of the Tupolev Tu-144 SST.

Kuznetsov's most powerful aviation engine is the Kuznetsov NK-321 that propels the Tupolev Tu-160 bomber and was formerly used in the later models of the Tu-144 supersonic transport. The NK-321 produced a maximum of about 55,000-pounds of thrust.

In 1959, Sergey Korolev ordered a new design of rocket engine from the Kuznetzov Bureau for the Global Rocket 1 Fractional Orbital Bombardment System intercontinental ballistic missile, which was developed but never deployed. The result was the NK-9, one of the first staged-combustion cycle rocket engines. The design was developed by Kuznetsov into the NK-15 and NK-33 engines in the 1960s, and claimed them to be the highest-performance rocket engines ever built, which were to propel the N1 lunar rocket—one that was never successfully launched. As of 2011, the aging NK-33 remains the most efficient LOX/Kerosene rocket engine ever created.
The Orbital Sciences Antares light-to-medium-lift launcher has two modified NK-33 in its first stage, a solid second stage and a hypergolic orbit stage. The NK-33s are first imported from Russia to the United States and then modified into Aerojet AJ26s, which involves removing some harnessing, adding U.S. electronics, qualifying it for U.S. propellants, and modifying the steering system.
The Antares rocket was successfully launched from NASA's Wallops Flight Facility on April 21, 2013. This marked the first successful launch of the NK-33 heritage engines built in early 1970s.
