Kuznetsov NK-144
The Kuznetsov NK-144 is an afterburning turbofan engine made by the Soviet Kuznetsov Design Bureau. Used on the early models of the Tupolev Tu-144 supersonic aircraft, it was very inefficient and was replaced with the Kolesov RD-36-51 The Kolesov RD-36 was a supersonic turbojet engine used on various Soviet aircraft projects. Design and development Developed at OKB-36 (P. A. Kolesov) and produced at the Rybinsk Motor-Building Plant, the RD-36-51A engine was developed fo ... turbojet engine.

Turbofan
A turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft engine, aircraft propulsion. The word "turbofan" is a combination of references to the preceding generation engine technology of the turbojet and the additional fan stage. It consists of a gas turbine engine which achieves mechanical energy from combustion, and a ducted fan that uses the mechanical energy from the gas turbine to force air rearwards. Thus, whereas all the air taken in by a turbojet passes through the combustion chamber and turbines, in a turbofan some of that air bypasses these components. A turbofan thus can be thought of as a turbojet being used to drive a ducted fan, with both of these contributing to the thrust. The ratio of the mass-flow of air bypassing the engine core to the mass-flow of air passing through the core is referred to as the bypass ratio. The engine produces thrust through a combination of these two portions working together. Engines that use more Propel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soviet Union
The Union of Soviet Socialist Republics. (USSR), commonly known as the Soviet Union, was a List of former transcontinental countries#Since 1700, transcontinental country that spanned much of Eurasia from 1922 until Dissolution of the Soviet Union, it dissolved in 1991. During its existence, it was the list of countries and dependencies by area, largest country by area, extending across Time in Russia, eleven time zones and sharing Geography of the Soviet Union#Borders and neighbors, borders with twelve countries, and the List of countries and dependencies by population, third-most populous country. An overall successor to the Russian Empire, it was nominally organized as a federal union of Republics of the Soviet Union, national republics, the largest and most populous of which was the Russian SFSR. In practice, Government of the Soviet Union, its government and Economy of the Soviet Union, economy were Soviet-type economic planning, highly centralized. As a one-party state go ...

Kuznetsov Design Bureau
The Kuznetsov Design Bureau (, also known as OKB-276) was a Russian design bureau for aircraft engines, administrated in Soviet times by Nikolai Dmitriyevich Kuznetsov. It was also known as (G)NPO Trud (or NPO Kuznetsov) and Kuybyshev Engine Design Bureau (KKBM). NPO Trud was replaced in 1994 by a Joint Stock Company (JSC), Kuznetsov R & E C. By the early 2000s the lack of funding caused by the poor economic situation in Russia had brought Kuznetsov to 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 Aircraft engines The Kuznetsov 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 (11.2 megawatts) and it wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tupolev Tu-144
The Tupolev Tu-144 (; NATO reporting name: Charger) is a Soviet supersonic airliner, supersonic passenger airliner designed by Tupolev in operation from 1968 to 1999. The Tu-144 was the world's first commercial supersonic transport aircraft with its prototype's maiden flight from Zhukovsky International Airport, Zhukovsky Airport on 31 December 1968, two months before the British-French Concorde. The Tu-144 was a product of the Tupolev Design Bureau, an OKB headed by aeronautics pioneer Aleksey Tupolev, and 16 aircraft were manufactured by the Voronezh Aircraft Production Association in Voronezh. The Tu-144 conducted 102 commercial flights, of which only 55 carried passengers, at an average service altitude of and cruised at a speed of around (Mach number, Mach 2). The Tu-144 first went supersonic on 5 June 1969, four months before Concorde, and on 26 May 1970 became the world's first commercial transport to exceed Mach 2. Reliability and developmental issues restricted the vi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kuznetsov NK-22
The Kuznetsov NK-22 is an afterburning turbofan engine, designed by the Kuznetsov Design Bureau. Development In April 1967, the Kuznetsov Design Bureau accepted an official request to create a new engine that would later be designated as the NK-22. The design of the NK-22 was based on the NK-144 engine used on the Tupolev Tu-144 The Tupolev Tu-144 (; NATO reporting name: Charger) is a Soviet supersonic airliner, supersonic passenger airliner designed by Tupolev in operation from 1968 to 1999. The Tu-144 was the world's first commercial supersonic transport aircraft wit ... SST. The first specimen of the engine was completed on April 10, 1968 and the first factory tests where passed in the same month. State tests took place in October 1970. The engines where later installed on Tu-22M0, M1, and M2 bombers. Serial production of the NK-22 started in 1969 and was terminated in 1984. A modernised version of the NK-22, the NK-23, first ran in July 1976 and was tested in flight ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Afterburning
An afterburner (or reheat in British English) is an additional combustion component used on some jet engines, mostly those on military aircraft, military supersonic aircraft. Its purpose is to increase thrust, usually for supersonic flight, takeoff, and aerial combat, combat. The afterburning process injects additional Jet fuel, fuel into a combustor ("burner") in the jet pipe behind (i.e., "after") the turbine, "reheating" the exhaust gas. Afterburning significantly increases thrust as an alternative to using a bigger engine with its added weight penalty, but at the cost of increased fuel consumption (decreased fuel efficiency) which limits its use to short periods. This aircraft application of "reheat" contrasts with the meaning and implementation of "reheat" applicable to gas turbines driving electrical generators and which reduces fuel consumption. Jet engines are referred to as operating ''wet'' when afterburning and ''dry'' when not. An engine producing maximum thrust w ...

Kolesov RD-36-51
The Kolesov RD-36 was a supersonic turbojet engine used on various Soviet aircraft projects. Design and development Developed at OKB-36 (P. A. Kolesov) and produced at the Rybinsk Motor-Building Plant, the RD-36-51A engine was developed for the Tu-144D supersonic passenger aircraft. A simplified version with a fixed nozzle for the high-altitude Myasishchev M-17 was designated RD-36-51B. The engine developed a thrust of . The RD36-51A engine passed all state bench and flight tests in 1973–75 (with flight testing on the Tu-144D). The engine's specifications were: * Maximum thrust at take-off = * Maximum thrust during supersonic cruise = altitude = , speed = * Maximum thrust during subsonic cruise= altitude = , speed = * Temperature = * Diameter = * Length = * Weight = For the high-altitude M-17 "Stratosphera" aircraft (NATO reporting name Mystic-A) a single-shaft TRD RD36-51B was created.
