Izdeliye 30
The Saturn ''izdeliye'' 30The Russian term , translit. ''izdeliye'' literally means "manufactured article" or "product". is the designation for a turbofan engine being developed by NPO Saturn to succeed the Lyulka-Saturn AL-41F1 for improved variants of the Sukhoi Su-57, as well as new potential tactical fighters such as the Sukhoi Su-75 Checkmate. Development In the 1990s, the collapse of the Soviet Union resulted in the disruption of funding and lengthy delays of the Mikoyan Project 1.44 for the MFI fifth-generation fighter program along with its engines, the variable cycle 18–tonne (177 kN, 40,000 lbf) class NPO Lyulka-Saturn AL-41F, internally designated ''izdeliye'' 20. In 1999, as the MFI and LFI programs were gradually being abandoned, the Russian Defence Ministry initiated the more affordable PAK FA next-generation fighter program to replace the MiG-29 and Su-27. The competition was announced in April 2001, and Sukhoi submitted its T-50 proposal with a pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Lyulka AL-31
Lyulka was a USSR aero engine design bureau and manufacturer from 1938 to the 1990s, when manufacturing and design elements were integrated as NPO Saturn based at Rybinsk. The Lyulka design bureau had its roots in the "Kharkiv Aviation Institute" ( Ukrainian SSR ) where Arkhip Mikhailovich Lyulka was working with a team designing the ''ATsN'' (Agregat Tsentralnovo Nadduva - Centralised supercharger) installation on the Petlyakov Pe-8 The Petlyakov Pe-8 (russian: Петляков Пе-8) was a Soviet heavy bomber designed before World War II, and the only four-engine bomber the USSR built during the war. Produced in limited numbers, it was used to bomb Berlin in August 1941. ... bomber. Lyul'ka was responsible for designing the first Soviet gas turbine engines. Preferring to steer away from copying captured German equipment, it succeeded in producing home grown engines.

Xian WS-15
The WS-15 (), codename Emei, is a Chinese afterburning turbofan engine designed by the Shenyang Aeroengine Research Institute and manufactured by the Xi'an Aero-Engine Corporation. The WS-15 is intended to power and enable supercruising on the Chengdu J-20. 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 the 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 engine and experienced significantly improved performance.

Pratt & Whitney F119
The Pratt & Whitney F119, company designation PW5000, is an afterburning turbofan engine developed by Pratt & Whitney for the Advanced Tactical Fighter (ATF) program, which resulted in the Lockheed Martin F-22 Raptor. The engine delivers thrust in the class and was designed for sustained supersonic flight without afterburners, or supercruise. Delivering almost 22% more thrust with 40% fewer parts than its F100 predecessor, the F119 allows the F-22 to achieve supercruise speeds of up to Mach 1.8.F-22 Flight Test Data . accessed August 8, 2007.

Full Authority Digital Engine Control
A full authority digital engine (or electronics) control (FADEC) is a system consisting of a digital computer, called an "electronic engine controller" (EEC) or "engine control unit" (ECU), and its related accessories that control all aspects of aircraft engine performance. FADECs have been produced for both piston engines and jet engines. History The goal of any engine control system is to allow the engine to perform at maximum efficiency for a given condition. Originally, engine control systems consisted of simple mechanical linkages connected physically to the engine. By moving these levers the pilot or the flight engineer could control fuel flow, power output, and many other engine parameters. The mechanical/hydraulic engine control unit for Germany's BMW 801 piston aviation radial engine of World War II was just one notable example of this in its later stages of development. This mechanical engine control was progressively replaced first by analog electronic engine control ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rossiyskaya Gazeta
' (russian: Российская газета, lit. Russian Gazette) is a Russian newspaper published by the Government of Russia. The daily newspaper serves as the official government gazette of the Government of the Russian Federation, publishing government-related affairs such as official decrees, statements and documents of state bodies, the promulgation of newly approved laws, Presidential decrees, and government announcements. History ''Rossiyskaya Gazeta'' was founded in 1990 by the Supreme Soviet of the Russian SFSR during the '' glasnost'' reforms in Soviet Union, shortly before the country dissolved in 1991. ''Rossiyskaya Gazeta'' became official government newspaper of the Russian Federation, replacing ''Izvestia'' and '' Sovetskaya Rossiya'' newspapers, which were both privatized after the Soviet Union's dissolution.

Specific Weight
The specific weight, also known as the unit weight, is the weight per unit volume of a material. A commonly used value is the specific weight of water on Earth at , which is .National Council of Examiners for Engineering and Surveying (2005). ''Fundamentals of Engineering Supplied-Reference Handbook'' (7th ed.). . Often a source of confusion is that the terms ''specific gravity'', and less often ''specific weight'', are also used for relative density. A common symbol for specific weight is , the Greek letter Gamma. Definition The specific weight, , of a material is defined as the product of its density, , and the standard gravity, : \gamma = \rho \, g The density of the material is defined as mass per unit volume, typically measured in kg/m3. The standard gravity is acceleration due to gravity, usually given in m/s2, and on Earth usually taken as . Unlike density, specific weight is not a fixed property of a material. It depends on the value of the gravitational acceleration, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuel Efficiency
Fuel efficiency is a form of thermal efficiency, meaning the ratio of effort to result of a process that converts chemical potential energy contained in a carrier (fuel) into kinetic energy or work. Overall fuel efficiency may vary per device, which in turn may vary per application, and this spectrum of variance is often illustrated as a continuous energy profile. Non-transportation applications, such as industry, benefit from increased fuel efficiency, especially fossil fuel power plants or industries dealing with combustion, such as ammonia production during the Haber process. In the context of transport, fuel economy is the energy efficiency of a particular vehicle, given as a ratio of distance traveled per unit of fuel consumed. It is dependent on several factors including engine efficiency, transmission design, and tire design. In most countries, using the metric system, fuel economy is stated as "fuel consumption" in liters per 100 kilometers (L/100 km) or kilometer ...
