The Kuznetsov NK-22 is an afterburning turbofan engine, designed by the Kuznetsov Design Bureau.
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. [2] The design of the NK-22 was based on the NK-144 engine used on the Tupolev Tu-144 SST. [2]
The first specimen of the engine was completed on April 10, 1968 [2] and the first factory tests where passed in the same month. [2] State tests took place in October 1970. [2] The engines where later installed on Tu-22M0, M1 and M2 bombers. [2] Serial production of the NK-22 started in 1969 and was terminated in 1984. [1]
A modernised version of the NK-22, the NK-23, first ran in July 1976 [1] and was tested in flight on a Tupolev Tu-22M2 bomber. [2] Despite having more thrust (220 kN) [3] than its predecessor, the NK-23 was not put into serial production. [3]

An afterburner is an additional combustion component used on some jet engines, mostly those on military supersonic aircraft. Its purpose is to increase thrust, usually for supersonic flight, takeoff, and combat. The afterburning process injects additional fuel into a combustor in the jet pipe behind the turbine, "reheating" the exhaust gas. Afterburning significantly increases thrust as an alternative to using a bigger engine with its attendant weight penalty, but at the cost of increased fuel consumption 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.
The General Electric F101 is an afterburning turbofan jet engine. It powers the Rockwell B-1 Lancer strategic bomber fleet of the USAF. In full afterburner it produces a thrust of more than 30,000 pounds-force (130 kN). The F101 was GE's first turbofan with an afterburner.
The Soloviev D-30 is a Soviet two-shaft low-bypass turbofan engine, officially referred to as a "bypass turbojet". It is probably the single most important turbofan engine developed in the Soviet Union. Development of the turbofan spurred numerous growth versions with increased fan diameter and modified component arrangements. Developed within an amazingly 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 SNECMA M53 is an afterburning turbofan engine developed for the Dassault Mirage 2000 fighter by Snecma. The engine is in service with different air forces, including the latest Mirage 2000-5 and 2000-9 multirole fighters.
The Lyulka AL-7 was a turbojet designed by Arkhip Mikhailovich Lyulka and produced by his Lyulka design bureau. The engine was produced between 1954 and 1970.
The Tumansky R-15 is an axial flow, single shaft turbojet with an afterburner. Its best known use is on the Mikoyan-Gurevich MiG-25.
The Saturn AL-31 is a family of axial flow turbofan engines, developed by the Lyulka design bureau in the Soviet Union, now NPO Saturn in Russia, originally as a 12.5-tonne powerplant for the Sukhoi Su-27 long range air superiority fighter. The AL-31 currently powers the Su-27 family of combat aircraft and some variants of the Chengdu J-10 multirole jet fighter. Assembly of the engine is also performed under license in India. Improved variants power the fifth-generation Sukhoi Su-57 and Chengdu J-20.
The Kuznetsov NK-32 is an afterburning three-spool low bypass turbofan jet engine which powers the Tupolev Tu-160 supersonic bomber, and was fitted to the later model Tupolev Tu-144LL supersonic transport. It produces 245 kN (55,000 lbf) of thrust in afterburner.
The NK-8 was a low-bypass turbofan engine built by the Kuznetsov Design Bureau, in the 90 kN (20,000 lbf) thrust class. It powered production models of the Ilyushin Il-62 and the Tupolev Tu-154A and B models.
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.
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 turbojet engine.

The Kuznetsov NK-87 is a low-bypass turbofan engine rated at 127.5 kN thrust. It powers the Lun-class ekranoplan. It is made by the soviet Kuznetsov Design Bureau.
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 Kuznetsov NK-93 was a civilian aircraft engine, a hybrid between a turbofan and a turboprop known as a propfan. The engine was also unique in having a separate duct around the contra-rotating propellers, as most other propfans are unducted. Once described in a respected aviation encyclopedia as "potentially the most fuel-efficient aircraft jet engine ever to be tested", the NK-93 was targeted for derivatives of Soviet/Russian airliners such as the Ilyushin Il-96, Tupolev Tu-204, and Tupolev Tu-330. Five in-flight engine tests were conducted on the NK-93 from December 2006 to December 2008.
The Kuznetsov NK-88 was an experimental alternative fuel turbofan engine, designed by the Kuznetsov Design Bureau.
