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] |
Shenyang J-35
The Shenyang J-35 () is a series of Chinese single-seater, twin-engine, all-weather, stealth multirole combat aircraft manufactured by Shenyang Aircraft Corporation (SAC), designed for air superiority and surface strike missions. The aircraft reportedly has two variants, a land-based variant designed for the People's Liberation Army Air Force (PLAAF), and a carrier-based variant optimized for catapult- assisted takeoff (CATOBAR) for the People's Liberation Army Naval Air Force (PLANAF). The Shenyang J-35A will also be exported to Pakistan Air Force (PAF). The aircraft was developed from the FC-31 Gyrfalcon ( zh, s=鹘鹰, p=Gǔ yīng), a stealth aircraft prototype that served as a demonstrator aiming to secure potential export customers after SAC lost the J-XX bid to the Chengdu Aircraft Industry Group. The People's Liberation Army, particularly the PLA Navy, later took an interest in the FC-31 project, leading to the prototype being further developed with a catapult laun ...

Huangshan
Huangshan ( zh, s=黄山),Bernstein, pp. 125–127. literally meaning the Yellow Mountain(s), is a mountain range in southern Anhui province in eastern China. It was originally called "Yishan", and it was renamed because of a legend that Emperor Xuanyuan once made alchemy here. Vegetation on the range is thickest below , with trees growing up to the treeline at . The area is well known for its scenery, sunsets, peculiarly-shaped granite peaks, Huangshan pine trees, hot springs, winter snow and views of the clouds from above. Huangshan is a frequent subject of traditional Chinese paintings and literature, as well as modern photography. It is a UNESCO World Heritage Site and one of China's major tourist destinations. Physical description The Huangshan mountain range has many peaks, some more than 1,000 meters (3,250 feet) high. The three tallest and best-known peaks are ''Lotus Peak'' (Lianhua Feng, 1,864 m), ''Bright Peak'' (Guangming Ding, 1,860 m) and ''Celestial Pe ...

Afterburner
An afterburner (or reheat in British English) 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 ("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 wet is at ''maximum power,'' while an engi ...

The United States Air Force (USAF) is the Air force, air service branch of the United States Department of Defense. It is one of the six United States Armed Forces and one of the eight uniformed services of the United States. Tracing its origins to 1 August 1907, as a part of the United States Army Signal Corps, the USAF was established by transfer of personnel from the Army Air Forces with the enactment of the National Security Act of 1947. It is the second youngest branch of the United States Armed Forces and the fourth in United States order of precedence, order of precedence. The United States Air Force articulates its core missions as air supremacy, intelligence, surveillance, target acquisition, and reconnaissance, global integrated intelligence, surveillance and reconnaissance, airlift, rapid global mobility, Strategic bombing, global strike, and command and control.

Guizhou WS-13
The WS-13 ( zh, 涡扇-13), codename Taishan, is a turbofan engine designed and manufactured by Guizhou Aircraft Industry Corporation to power the CAC/PAC JF-17 Thunder lightweight multirole fighter jointly developed by China and Pakistan, and in the near future the Shenyang FC-31 fifth-generation stealth fighter currently under development. Design and development China began development of the Taishan in 2000 to create a domestic engine for replacing the Klimov RD-93 turbofan, which had been selected in the 1990s to power the JF-17 lightweight fighter. It is designed to produce 86 kN (19,000 lb) of thrust with afterburner and have a life span of 2,200 hours; an improved version providing up to 93 kN (21,000 lb) of thrust with afterburner was also developed. The WS-13 Taishan was certified in 2007 and serial production began in 2009. The 18 March 2010 edition of the ''HKB Report'' stated that a JF-17 equipped with the WS-13 completed its first successf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xian WS-15
The Shenyang WS-15 (), codename Emei, is a Chinese afterburning turbofan engine designed by the Shenyang Aeroengine Research Institute and manufactured by the Shenyang Liming Aircraft Engine Company. The WS-15 is intended to become the main engine of the Chengdu J-20 stealth aircraft, enabling it to supercruise, improve its range, manoeuvrability and upgrade potential for future weapon systems. It will eventually replace the Shenyang WS-10, which currently serves as the interim engine of J-20, while the WS-15 is being refined. Design and development Development of the WS-15 afterburning turbofan engine began in the early 1990s. In 2005, the engine performed successfully on the testbed. An image of the core appeared at 2006 China International Aviation & Aerospace Exhibition. In 2009, a prototype achieved and a thrust-to-weight ratio of 9. The thrust target was reported as in 2012. In March 2022, Chinese state media reported that the J-20 had performed trials with the eng ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

General Electric F414
The General Electric F414 is an American afterburning turbofan engine in the 22,000- pound (98 kN) thrust class produced by GE Aerospace (formerly GE Aviation). The F414 originated from GE's widely used F404 turbofan, enlarged and improved for use in the Boeing F/A-18E/F Super Hornet. The engine was developed from the F412 non-afterburning turbofan planned for the A-12 Avenger II, before it was canceled. Design and development Origins GE evolved the F404 into the F412-GE-400 non-afterburning turbofan for the McDonnell Douglas A-12 Avenger II. After the cancellation of the A-12 in 1991, the research was directed toward an engine for the F/A-18E/F Super Hornet. GE successfully pitched the F414 as a low-risk derivative of the F404, rather than a riskier new engine. The F414 engine was originally envisioned as not using any materials or processes not used in the F404, and was designed to fit in the same footprint as the F404."Confident GE heads to F414 CDR next month" (1994).

Eurojet EJ200
The Eurojet EJ200 is a military low-bypass turbofan used as the powerplant of the Eurofighter Typhoon. The engine is largely based on the Rolls-Royce XG-40 technology demonstrator, which was developed in the 1980s. The EJ200 is built by the EuroJet Turbo GmbH consortium. The EJ200 is also used in the Bloodhound LSR supersonic land speed record attempting car. Development Rolls-Royce XG-40 Rolls-Royce began development of the XG-40 technology demonstrator engine in 1984. Development costs were met by the British government (85%) and Rolls-Royce. On 2 August 1985, Italy, West Germany and the UK agreed to go ahead with the Eurofighter. The announcement of this agreement confirmed that France had chosen not to proceed as a member of the project. One issue was French insistence that the aircraft be powered by the Snecma M88, in development at the same time as the XG-40.
