Nikolai Dmitriyevich Kuznetsov was a Chief Designer of the Soviet Design Bureau OKB-276 which deals with the development, manufacture and distribution of equipment, especially aircraft engines, turbines and gearboxes.
Kuznetsov started his career as a professional coppersmith and he began working as a mechanic. In 1930 graduated from the school and enrolled at the Moscow Aviation College where he studied part-time and worked as a mechanic. In 1933 he joined the Aircraft Faculty in the Zhukovsky Air Force Engineering Academy. There he studied under Prof. Nikolai Jegorowitsch Schukowski - then the head of the department for aircraft engines research. Kuznetsov received a degree with honors in November 1938. [1]
The topic of his diploma there was on motors: four-carburettor, 28-cylinder with a 4-star air-cooled power of 1500 hp at 3400 rpm and at an altitude of 6000 meters with two-high-speed driven centrifugal blowers. [2]
In April 1939, Kuznetsov became a member of Communist Party organization of the academy and was elected a faculty. On 4 April 1941 he successfully defended his thesis on the structural integrity of aircraft engines while under NKVD interrogation. In the period from July to September 1942 he trained under a senior engineer of 239 fighter division 6th air force who met George Malenkov and praised the ability of Kuznetsov and subsequently sent his deputy to become a Designer at the Ufa Aviation Plant.[ citation needed ]
Here Kuznetsov worked from 1943 to 1949 first under the leadership of Klimov then as chief designer. In 1949 he was transferred to Kuybyshev (currently the City of Samara) which was headed by the State union pilot plant number 2 on the development and manufacture of advanced jet engines now known as Kuznetsov Design Bureau. There he worked with Sergei Korolev, the famous Soviet rocket designer under NKVD supervision and control. [ citation needed ]
After World War II, captured German turbine specialists were brought along with some of the gas turbines to the Soviet Union by the NKVD. In addition to the already established Jumo 004 and BMW 003 engines they brought along the design documents and plans of Jumo 022 project.[ citation needed ]
In 1949, Kuznetsov was appointed as chief designer of jet engines at OKB-276 ("Experimental design bureau-276") and started developing turboprop designs further with the help of the German specialists being held in NKVD custody. [ citation needed ]
It proved to be a successful engine and was completed in 1955. The new turboprop engine, named Kuznetsov NK-12, displayed great performance and was developed up to 11,000 kW. It was used in the Antonov An-22 aircraft, A-90 Orlyonok Ekranoplane and the Tupolev Tu-95 strategic bomber among others. The later models produced around 15,000 kW. [3]
In 1954, he began work on a two-flow jet engine with afterburner, called the Kuznetsov NK-6, which was never completed.[ citation needed ]
In 1957, he received the Order of Hero of Socialist Labor for his contributions.[ citation needed ]
From 1959 onwards, he was also involved in the development of engines for the projected Soviet N1 Moon rocket. The primary engines for the development rockets were Kuznetsov NK-15 and Kuznetsov NK-15V (later developed into Kuznetsov NK-33 and Kuznetsov NK-43). Ultimately, these designs were successful but arrived too late. By the time the bugs in this very advanced design were rectified, the N1 rocket program had been cancelled. [4] [5] Several stockpiled NK-33 engines were refurbished and modified by Aerojet and used for the Orbital Sciences Antares. [6]
In the 1960s he developed aircraft engines specifically for the world's first supersonic transport aircraft to fly Tupolev Tu-144, the Kuznetsov NK-144 turbofan. This was however inefficient and replaced by the Kolesov RD-36.[ citation needed ]
Based on these design experiences, the engine Kuznetsov NK-321 (also known as NK-32-1) was developed later for the supersonic, variable-geometry heavy bomber Tupolev Tu-160, which is also in the more powerful version of the Tupolev Tu-144 (version Tu-144LL).[ citation needed ]
In the late 1980s OKB- 267 began the development of the fuel sipping Turbo Fan Engine Kuznetsov NK-93, which has a by-pass ratio of almost 17:1 and thus an engine of a unique design in the world.[ citation needed ]
Sharashkas were secret research and development laboratories operating from 1930 to the 1950s within the Soviet Gulag labor camp system, as well as in other facilies under the supervision of the Soviet secret service. Formally various secret R&D facilities were called "special design bureau" Russian: особое конструкторское бюро, ОКБ and similar terms. Etymologically, the word sharashka derives from a Russian slang expression sharashkina kontora,, an ironic, derogatory term to denote a poorly-organized, impromptu, or bluffing organization, which in its turn comes from the criminal argot term sharaga (шарага) for a band of thieves, hoodlums, etc.)
The Tupolev Tu-85 was a Soviet prototype strategic bomber based on the Tu-4, an unlicensed, reverse engineered copy of the Boeing B-29 Superfortress. It was the ultimate development of the B-29 family, being over 50% heavier than its progenitor and had nearly double the range. Only two prototypes were built before the program was cancelled in favor of the turboprop powered Tupolev Tu-95 bomber which could cover the same range at a far higher speed.
Tupolev, officially Public Joint Stock Company Tupolev, is a Russian aerospace and defence company headquartered in Basmanny District, Moscow.
The staged combustion cycle is a power cycle of a bipropellant rocket engine. In the staged combustion cycle, propellant flows through multiple combustion chambers, and is thus combusted in stages. The main advantage relative to other rocket engine power cycles is high fuel efficiency, measured through specific impulse, while its main disadvantage is engineering complexity.
Vladimir Nikolayevich Chelomey or Chelomei was a Soviet engineer and designer in the missile program of the former Soviet Union. He invented the first Soviet pulse jet engine and was responsible for the development of the world's first anti-ship cruise missiles and the ICBM program of the Soviet Union such as the UR-100, UR-200, UR-500 and UR-700.
OKB is a transliteration of the Russian initials of "опытно-конструкторское бюро" – opytno konstruktorskoye byuro, meaning 'experiment and design bureau'. During the Soviet era, OKBs were closed institutions working on design and prototyping of advanced technology, usually for military applications. The corresponding English language term for such a bureau's activity is "research and development".
The Soloviev D-30 is a Soviet two-shaft low-bypass turbofan engine, officially referred to as a "bypass turbojet". It is one of the most powerful turbofan engines developed in the Soviet Union. Development of the turbofan spurred numerous growth versions with increased fan diameter and modified component arrangements. Developed in a short period of time, the D-30 turned out to be one of the most reliable engines in the history of Soviet engine development, and it was recognized with the USSR State Prize.
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 (G)NPO Trud and Kuybyshev Engine Design Bureau (KKBM).
The Kuznetsov NK-12 is a Soviet turboprop engine of the 1950s, designed by the Kuznetsov design bureau. The NK-12 drives two large four-bladed contra-rotating propellers, 5.6 m (18 ft) diameter (NK-12MA), and 6.2 m (20 ft) diameter (NK-12MV). It is the most powerful turboprop engine to enter service.
The Tupolev Tu-95LAL experimental aircraft which flew from 1961 to 1965 was a modified Tupolev Tu-95 Soviet bomber aircraft, analogous to the United States' earlier Convair NB-36H. It was intended to see whether a nuclear reactor could be used to power an aircraft, primarily testing airborne operation of a reactor and shielding for components and crew. The reactor did not actually power the aircraft.
UEC-Aviadvigatel JSC is a Russian developer and builder of aircraft engines, most notably jet engines for commercial aircraft. Based at the Perm Engine Plant, its products power the Ilyushin Il-76MF, Ilyushin Il-96, Tupolev Tu-204, and Tupolev Tu-214. It also designs and builds high-efficiency gas turbine units for electric power stations and for gas pumping plants. The company has its background in the Experimental Design Bureau-19 plant, set up to manufacture aircraft engines.
The Kuznetsov NK-86 is a low bypass turbofan engine used on the Ilyushin Il-86 rated at 13,000 kgf or 28,600 lbf thrust. It is made by the Soviet Kuznetsov Design Bureau. It is an upgraded version of the Kuznetsov NK-8.
JSC Kuznetsov is one of the leading Russian producers of aircraft engines, liquid-propellant rocket engines as well as aeroderivative gas turbines and modular stations.
The Kuznetsov NK-14A was an onboard nuclear-powered engine which was made to be used on the Tupolev Tu-119 nuclear-powered aircraft, designed and built by the Soviet Kuznetsov Design Bureau. The design of the plane was based on a modified Tupolev Tu-95 and would be fitted with two Kuznetsov NK-14A nuclear-fuelled engines inboard fed with heat from a fuselage mounted reactor and two Kerosene-fed Kuznetsov NK-12 turboprops outboard.
Sergei Konstantinovich Tumansky was a designer of Soviet aircraft engines and the chief designer in the Tumansky Design Bureau, OKB-300. He worked in TsIAM, and at the aircraft-engine plant N 29, in Zaporozhye.
The Kuznetsov NK-25 is a turbofan aircraft engine used in the Tupolev Tu-22M strategic bomber. It can equal the NK-321 engine as one of the most powerful supersonic engines in service today. It is rated at 245 kN (55,000 lbf) thrust. The three shaft engine we call the NK-25 was designed in the years 1972–1974. It is made by the Soviet Kuznetsov Design Bureau.
The Dobrynin VD-4K was a Soviet six-bank, 24-cylinder, turbo-compound, inline engine developed after the end of World War II. It was superseded by turboprop engines before it could be widely used.
The Kuznetsov NK-6 was a low-bypass afterburning turbofan engine, designed by the Kuznetsov Design Bureau.
