The engine's name is a combination of the Roman numeral V, symbolizing the five original members of the International Aero Engines consortium, formed in 1983 to produce the engine, and 2500, which represents the 25,000-pound-force (110 kN) thrust produced by the original engine model, the V2500-A1.
The Williams F107 (company designation WR19) is a small turbofan engine made by Williams International.The F107 was designed to propel cruise missiles.It has been used as the powerplant for the AGM-86 ALCM, and BGM-109 Tomahawk, as well as the experimental Kaman KSA-100 SAVER and Williams X-Jet flying platform.
The higher-thrust variants, GE90-110B1 and -115B, have a different architecture from that of the earlier GE90 versions. General Electric incorporated an advanced larger diameter fan made from composite materials which enhanced thrust at low flight speeds. However, GE also needed to increase core power to improve net thrust at high flight speeds.
For flight demonstration, YF120s were fitted with the larger fan, unlike the YF119 which used its original small fan. As a result, both demonstrator aircraft had higher performance with the YF120s than with the YF119s. [5] The YF120-powered the YF-22 and YF-23 to supercruise speeds of Mach 1.58 and Mach 1.72 respectively. [6] [7] [N 1]
The CF6-80E1 has the highest thrust power of CF6-80 Series family, with the fan tip diameters increased to 96.2 in (2.443m), and an overall pressure ratio of 32.6 and bypass ratio of 5.3. [8] The 68,000 to 72,000 lbf (300 to 320 kN) variant competes with the Rolls-Royce Trent 700 and the Pratt & Whitney PW4000 to power the Airbus A330 .
The high-bypass turbofan engines used on many modern airliners is an example of a very successful and popular use of ducted fan design. The duct increases thrust efficiency by up to 90% in most cases [citation needed], in comparison to a similar-sized propeller in free air. Ducted fans are quieter, and offer good opportunities for thrust vectoring.
The Honeywell/ITEC F124 is a low-bypass turbofan engine derived from the civilian Honeywell TFE731.The F125 is an afterburning version of the engine. The engine began development in the late 1970s for the Republic of China (Taiwan) Air Force AIDC F-CK Indigenous Defence Fighter (IDF), and it first ran in 1979.
The fan is housed in 134 in (340 cm) diameter case. [26] The GE9X has 16 blades, whereas the similarly sized GE90 has 22 and the smaller GEnx has 18. Having fewer fan blades reduces the engine weight, improves aerodynamic efficiency, and allows the low pressure (LP) fan and booster to spin faster to better match its speed with the LP turbine.
