GE Passport
The General Electric Passport is a turbofan developed by GE Aviation for large business jets. It was selected in 2010 to power the Bombardier Global 7500/8000, first run on June 24, 2013, and first flown in 2015. It was certified in April 2016 and powered the Global 7500 first flight on November 4, 2016, before its 2018 introduction. It produces of thrust, a range previously covered by the General Electric CF34. A smaller scaled CFM LEAP, it is a twin-spool axial engine with a 5.6:1 bypass ratio and a 45:1 overall pressure ratio and is noted for its large one-piece fan 18-blade titanium blisk. Development GE's eCore research program developing a common architecture for business, narrowbody and regional jets resulted in the CFM LEAP succeeding the CFM56 aboard the Boeing 737 MAX and Airbus A320neo. After a market study, GE pursued the long-range, large business jet and selected a thrust to exploit technology acquired for its commercial and military engine programs. Prelim ...

Icing Conditions
In aviation, icing conditions are atmospheric conditions that can lead to the formation of water ice on an aircraft. Ice accretion and accumulation can affect the external surfaces of an aircraft – in which case it is referred to as ''airframe icing'' – or the engine, resulting in carburetor icing, air inlet icing or more generically ''engine icing''. These phenomena may possibly but do not necessarily occur together. Both airframe and engine icing have resulted in numerous fatal accidents in aviation history. Not all aircraft, especially general aviation aircraft, are certified for ''flight into known icing'' (FIKI) – that is flying into areas with icing conditions certain or likely to exist, based on pilot reports, observations, and forecasts. In order to be FIKI-certified, aircraft must be fitted with suitable ice protection systems to prevent accidents by icing. Definition Icing conditions exist when the air contains droplets of supercooled liquid water. They freeze ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Victorville, California
Victorville is a city in Victor Valley in San Bernardino County, California. Its population as of the 2020 census was 134,810. History In 1858, Aaron G. Lane came to what is now known as Victorville and founded a waystation called "Lane's Crossing." For many years it provided shelter and supplies for people journeying across the desert from the east to San Bernardino. Lane's Crossing was on the Mojave River on today's Turner Road, two miles north of where Interstate 15 crosses the river. Lane was a veteran of the Mexican–American War who had had malaria during that war. Originally he migrated west to join the California gold rush, but he learned that he could make a better living selling supplies to the miners. Lane settled in Ione, near Sutter's Mill in northern California, during those years, but migrated to San Bernardino in 1857. He settled on the Mojave River in 1858, where he established his waystation. He later sold out to Texan John Fry Miller, who changed the name ...

Boeing 747
The Boeing 747 is a large, long-range wide-body airliner designed and manufactured by Boeing Commercial Airplanes in the United States between 1968 and 2022. After introducing the 707 in October 1958, Pan Am wanted a jet times its size, to reduce its seat cost by 30%. In 1965, Joe Sutter left the 737 development program to design the 747, the first twin-aisle airliner. In April 1966, Pan Am ordered 25 Boeing 747-100 aircraft and in late 1966, Pratt & Whitney agreed to develop the JT9D engine, a high-bypass turbofan. On September 30, 1968, the first 747 was rolled out of the custom-built Everett Plant, the world's largest building by volume. The first flight took place on February 9, 1969, and the 747 was certified in December of that year. It entered service with Pan Am on January 22, 1970. The 747 was the first airplane dubbed "Jumbo Jet", the first wide-body airliner. The 747 is a four-engined jet aircraft, initially powered by Pratt & Whitney JT9D turbofan engin ...

Bird Strike
A bird strike—sometimes called birdstrike, bird ingestion (for an engine), bird hit, or bird aircraft strike hazard (BASH)—is a collision between an airborne animal (usually a bird or bat) and a moving vehicle, usually an aircraft. The term is also used for bird deaths resulting from collisions with structures such as power lines, towers and wind turbines (see Bird–skyscraper collisions and Towerkill). A significant threat to flight safety, bird strikes have caused a number of accidents with human casualties. There are over 13,000 bird strikes annually in the US alone. However, the number of major accidents involving civil aircraft is quite low and it has been estimated that there is only about 1 accident resulting in human death in one billion (109) flying hours. The majority of bird strikes (65%) cause little damage to the aircraft; however, the collision is usually fatal to the bird(s) involved. The Canada goose has been ranked as the third most hazardous wildlife spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peebles, Ohio

Shroud
Shroud usually refers to an item, such as a cloth, that covers or protects some other object. The term is most often used in reference to ''burial sheets'', mound shroud, grave clothes, winding-cloths or winding-sheets, such as the famous Shroud of Turin, ''tachrichim'' (burial shrouds) that Jews are dressed in for burial, or the white cotton ''kaffan'' sheets Muslims are wrapped in for burial. A traditional Orthodox Jewish shroud consists of a tunic; a hood; pants that are extra-long and sewn shut at the bottom, so that separate foot coverings are not required; and a belt, which is tied in a knot shaped like the Hebrew letter ''shin'', mnemonic of one of God's names, Shaddai. Traditionally, mound shrouds are made of white cotton, wool or linen, though any material can be used so long as it is made of natural fibre. Intermixture of two or more such fibres is forbidden, a proscription that ultimately derives from the Torah, ''viz.'', Deut. 22:11. An especially pious Jewish ma ...

Turbine
A turbine ( or ) (from the Greek , ''tyrbē'', or Latin ''turbo'', meaning vortex) is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. The work produced by a turbine can be used for generating electrical power when combined with a generator.Munson, Bruce Roy, T. H. Okiishi, and Wade W. Huebsch. "Turbomachines." Fundamentals of Fluid Mechanics. 6th ed. Hoboken, NJ: J. Wiley & Sons, 2009. Print. A turbine is a turbomachine with at least one moving part called a rotor assembly, which is a shaft or drum with blades attached. Moving fluid acts on the blades so that they move and impart rotational energy to the rotor. Early turbine examples are windmills and waterwheels. Gas, steam, and water turbines have a casing around the blades that contains and controls the working fluid. Credit for invention of the steam turbine is given both to Anglo-Irish engineer Sir Charles Parsons (1854–1931) for invention of the reaction turbine, and to ...

Combustor
A combustor is a component or area of a gas turbine, ramjet, or scramjet engine where combustion takes place. It is also known as a burner, combustion chamber or flame holder. In a gas turbine engine, the ''combustor'' or combustion chamber is fed high-pressure air by the compression system. The combustor then heats this air at constant pressure as the fuel/air mix burns. As it burns the fuel/air mix heats and rapidly expands. The burned mix is exhausted from the combustor through the nozzle guide vanes to the turbine. In the case of a ramjet or scramjet engines, the exhaust is directly fed out through the nozzle. A combustor must contain and maintain stable combustion despite very high air flow rates. To do so combustors are carefully designed to first mix and ignite the air and fuel, and then mix in more air to complete the combustion process. Early gas turbine engines used a single chamber known as a can-type combustor. Today three main configurations exist: can, annular, and c ...
