Information: - The turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft propulsion. The word "turbofan" is a portmanteau of "turbine" and "fan": the "turbo" portion refers to a gas turbine engine which achieves mechanical energy from combustion, and the "fan", a ducted fan that uses the mechanical energy from the gas turbine to accelerate air rearwards. Thus, whereas all the air taken in by a turbojet passes through the turbine (through the combustion chamber), in a turbofan some of that air bypasses the turbine. A turbofan thus can be thought of as a turbojet being used to drive a ducted fan, with both of those contributing to the thrust. The ratio of the mass-flow of air bypassing the engine core compared 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 in concert; engines that use more jet thrust relative to fan thrust are known as "low-bypass turbofans", conversely those that have considerably more fan thrust than jet thrust are known as "high-bypass". Most commercial aviation jet engines in use today are of the high-bypass type, and most modern military fighter engines are low-bypass. Afterburners are not used on high-bypass turbofan engines but may be used on either low-bypass turbofan or turbojet engines. - The Soloviev D - 30 is a Soviet two - shaft low - bypass turbofan engine , officially referred to as a '' bypass turbojet . '' A supersonic afterburner version , the D - 30F6 , is used in the Mikoyan - Gurevich MiG - 31 interceptor , while the non-afterburning civilian versions , the D - 30Kp and D - 30KU are used in the Ilyushin Il - 62M and Tupolev Tu - 154M airliners , and in the Ilyushin Il - 76MD , TD heavy cargo aircraft . - Aviation is the practical aspect or art of aeronautics, being the design, development, production, operation and use of aircraft, especially heavier than air aircraft. The word "aviation" was coined by French writer and former naval officer Gabriel La Landelle in 1863, from the verb "avier" (synonymous flying), itself derived from the Latin word "avis" ("bird") and the suffix "-ation". - TurboJET is the brand name for the operations of the Hong Kong-headquartered Shun Tak-China Travel Ship Management Limited, which was established from the joint venture between Shun Tak Holdings Limited and China Travel International Investment Hong Kong Limited in July 1999. It operates hydrofoil ferry services in southern China. - The Ilyushin Il-76 (NATO reporting name: Candid) is a multi-purpose four-engine turbofan strategic airlifter designed by the Soviet Union's Ilyushin design bureau. It was first planned as a commercial freighter in 1967, as a replacement for the Antonov An-12. It was designed to deliver heavy machinery to remote, poorly served areas. Military versions of the Il-76 have been widely used in Europe, Asia and Africa, including use as an aerial refueling tanker or command center.
