Williams EJ22
The Williams EJ22 was a small turbofan engine that was being developed by Williams International for very light jet (VLJ) aircraft applications. Development Williams International had been building small turbofan engines for cruise missile applications since the 1960s, and had successfully entered the general aviation market in 1992 with the FJ44 engine. That same year, NASA initiated a program, Advanced General Aviation Transport Experiments (AGATE), to partner with manufacturers and help develop technologies that would revitalize the sagging general aviation industry. In 1996, Williams joined AGATE's General Aviation Propulsion (GAP) program to develop a clean-sheet fuel-efficient turbofan engine that would be even smaller than the FJ44 and designated the FJX-2 engine. This provided $100 million in research and development funding for the new engine. Initially, Williams contracted with Burt Rutan's Scaled Composites to design and build the Williams V-Jet II, a Very Light ...

Burt Rutan
Elbert Leander "Burt" Rutan (; born June 17, 1943) is a retired American aerospace engineer and entrepreneur noted for his originality in designing light, strong, unusual-looking, and energy-efficient air and space craft. He designed the record-breaking Voyager, which in 1986 was the first plane to fly around the world without stopping or refueling, and the Virgin Atlantic GlobalFlyer, which in 2006 set the world record for the fastest (342 mph/551 km/h in 67 hours) and longest (25,766 miles/41,466 km) nonstop non-refueled circumnavigation flight in history. In 2004, Rutan's sub-orbital spaceplane design SpaceShipOne became the first privately funded spacecraft to enter the realm of space, winning the Ansari X-Prize that year for achieving the feat twice within a two-week period. With his VariEze and Long-EZ designs, which first flew in 1975 and 1979 respectively, Rutan is responsible for helping popularize both the canard configuration and the use of moldless c ...

2000s Turbofan Engines
S, or s, is the nineteenth letter in the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''ess'' (pronounced ), plural ''esses''. History Origin Northwest Semitic šîn represented a voiceless postalveolar fricative (as in 'ip'). It originated most likely as a pictogram of a tooth () and represented the phoneme via the acrophonic principle. Ancient Greek did not have a phoneme, so the derived Greek letter sigma () came to represent the voiceless alveolar sibilant . While the letter shape Σ continues Phoenician ''šîn'', its name ''sigma'' is taken from the letter ''samekh'', while the shape and position of ''samekh'' but name of ''šîn'' is continued in the '' xi''. Within Greek, the name of ''sigma'' was influenced by its association with the Greek word (earlier ) "to hiss". The original name of the letter "sigma" may have been ''san'', but due to the complica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thrust-specific Fuel Consumption
Thrust-specific fuel consumption (TSFC) is the fuel efficiency of an engine design with respect to thrust output. TSFC may also be thought of as fuel consumption (grams/second) per unit of thrust (newtons, or N), hence ''thrust-specific''. This figure is inversely proportional to specific impulse, which is the amount of thrust produced per unit fuel consumed. TSFC or SFC for thrust engines (e.g. turbojets, turbofans, ramjets, rockets, etc.) is the mass of fuel needed to provide the net thrust for a given period e.g. lb/(h·lbf) (pounds of fuel per hour-pound of thrust) or g/(s·kN) (grams of fuel per second-kilonewton). Mass of fuel is used, rather than volume (gallons or litres) for the fuel measure, since it is independent of temperature. Specific fuel consumption of air-breathing jet engines at their maximum efficiency is more or less proportional to exhaust speed. The fuel consumption ''per mile'' or ''per kilometre'' is a more appropriate comparison for aircraft that travel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pratt & Whitney Canada PW600
The Pratt & Whitney Canada PW600 series is a family of small turbofan engines developed by Pratt & Whitney Canada producing between of thrust and powering the Eclipse 500/550, the Cessna Citation Mustang and the Embraer Phenom 100. Development The thrust PW625F demonstrator engine was first run on 31 October 2001. It flew in late 2002. In 2002, the PW610F was selected for the Eclipse 500 twinjet, replacing the EJ22 as Williams was unable to reach sufficient reliability. The thrust engine was certified by Transport Canada on 27 July 2006. The aircraft received a preliminary certification on 27 July 2006 and was forst delivered on 31 December 2006. The Eclipse 500 production was halted in October 2008 after 260 were delivered, and 33 of the updated Eclipse 550 were delivered between 2014 and 2017. The larger PW615F was selected to power the Cessna Citation Mustang in January 2003. The thrust engine was certified on June 26, 2006. The aircraft was certified on 8 September 2 ...

Very Light Jet
A very light jet (VLJ), entry-level jet or personal jet, previously known as a microjet, is a category of small business jets seating four to eight people. VLJs are considered the lightest business jets and are approved for single-pilot operation. History The first small jet-powered civil aircraft, the 1950s Morane-Saulnier MS.760 Paris, has been retroactively suggested as being the first VLJ, as it seats four with a single pilot and is smaller than modern VLJs. The production of MS.760 differs from modern business jets in having a sliding canopy for cabin access rather than a door; a six-seat version with an enclosed cabin and a conventional door was canceled after a single prototype was built. Two unbuilt Cessna aircraft of the 1950s and 1960s would have met the definition of a VLJ. The first was the 407, a four-seat civil version of the T-37 jet trainer proposed in 1959; however, the 407 never progressed past the mockup stage due to insufficient customer interest. The seco ...

Advanced General Aviation Transport Experiments
The Advanced General Aviation Transport Experiments (AGATE) project was a consortium of NASA, the FAA, the general aviation industry and a number of universities. Its goal was to create a Small Aviation Transportation System (SATS) as an alternative to short-range automotive trips for both private and business transportation needs. The Small Aviation Transportation System will make many time-sensitive short-haul trips more affordable for business, medical, public safety and recreational pursuits. Consortium creation The AGATE Alliance was launched in 1994 and born out of an effort to stem the gradual decline of general aviation innovation in the United States. It played an instrumental role in the forging of joint technology development and testing partnerships between Government, industry and vital non-profit contributors. The AGATE Alliance was organized as an operating partnership between government, industry, and academia established to develop new ways of reviving the troubl ...
