MD-90
The McDonnell Douglas (later Boeing) MD-90 is an American five-abreast single-aisle airliner developed by McDonnell Douglas from its successful model MD-80. The airliner was produced by the developer company until 1997 and then by Boeing Commercial Airplanes. It was a stretched derivative of the MD-80 and thus the third generation of the DC-9 family. After the more fuel-efficient IAE V2500 high-bypass turbofan was selected, Delta Air Lines became the launch customer on November 14, 1989. The MD-90 first flew on February 22, 1993, and the first delivery was in February 1995 to Delta. The MD-90 competed with the Airbus A320ceo family and the Boeing 737 Next Generation. Its 5 ft (1.4 m) longer fuselage seats 153 passengers in a mixed configuration over up to 2,455 nmi (4,547 km), making it the largest member of the DC-9 family. It kept the MD-88's electronic flight instrument system (EFIS). The shrunken derivative of MD-80 or shorter variant of MD-90, originally mar ...

Boeing 717
The Boeing 717 is an American five-abreast single-aisle airliner produced by Boeing Commercial Airplanes. The twin-engine airliner was developed for the 100-seat market and originally marketed by McDonnell Douglas as the MD-95. It was a shortened derivative of the company's successful airliner, the MD-80, and thus the third generation of the DC-9 family. Capable of seating up to 134 passengers, the 717 has a design range of . It is powered by two Rolls-Royce BR715 turbofan engines mounted at the rear of the fuselage. The first order for the airliner was placed with McDonnell Douglas in October 1995 by ValuJet Airlines (later AirTran Airways).

IAE V2500
The IAE V2500 is a two-shaft high-bypass turbofan engine built by International Aero Engines (IAE) which powers the Airbus A320 family, the McDonnell Douglas MD-90, and the Embraer C-390 Millennium. The engine's name is a combination of the Roman numeral V, symbolizing the five original members of the International Aero Engines consortium, which was formed in 1983 to produce the V2500 engine. The 2500 represents the produced by the original engine model, the V2500-A1. FAA type certification for the V2500 was granted in 1988. The maintenance, repair, and operations market for V2500 is close to as of 2015. Development Rolls-Royce based the 10-stage HP compressor on a scale-up of the RC34B eight-stage research unit used in the RB401-06 Demonstrator Engine, but with two additional stages added to the front and rear of the compressor spool. Pratt & Whitney developed the combustor and the 2-stage air-cooled HP turbine, while the Japanese Aero Engine Corporation provided ...

MD-94X
The McDonnell Douglas MD-94X was a planned propfan-powered airliner, intended to begin production in 1994. Announced in January 1986, the aircraft was to seat between 160 and 180 passengers, possibly using a twin-aisle configuration. An all-new design that was investigated internally since at least 1984, the MD-94X was developed in the mid-1980s to compete with the similar Boeing 7J7. The price of oil would have to be at least US$1.40 per gallon for McDonnell Douglas to build the plane, though. Configuration was similar to the MD-80, but advanced technologies such as canard noseplanes, laminar and turbulent boundary layer control, side-stick flight control (via fiber optics), and aluminum-lithium alloy construction were under consideration. Airline interest in the brand-new propfan technology was weak despite claims of up to a 60% reduction in fuel use, and both aircraft were canceled. Under development at the same time were two propfan-powered commercial variants of the MD-8 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glass Cockpit
A glass cockpit is an aircraft cockpit that features electronic (digital) flight instrument displays, typically large LCD screens, rather than the traditional style of analog dials and gauges. While a traditional cockpit relies on numerous mechanical gauges (nicknamed "steam gauges") to display information, a glass cockpit uses several multi-function displays driven by flight management systems, that can be adjusted to display flight information as needed. This simplifies aircraft operation and navigation and allows pilots to focus only on the most pertinent information. They are also popular with airline companies as they usually eliminate the need for a flight engineer, saving costs. In recent years the technology has also become widely available in small aircraft. As aircraft displays have modernized, the sensors that feed them have modernized as well. Traditional gyroscopic flight instruments have been replaced by electronic attitude and heading reference systems (AHRS ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Los Angeles Times
The ''Los Angeles Times'' (abbreviated as ''LA Times'') is a daily newspaper that started publishing in Los Angeles in 1881. Based in the LA-adjacent suburb of El Segundo since 2018, it is the sixth-largest newspaper by circulation in the United States. The publication has won more than 40 Pulitzer Prizes. It is owned by Patrick Soon-Shiong and published by the Times Mirror Company. The newspaper’s coverage emphasizes California and especially Southern California stories. In the 19th century, the paper developed a reputation for civic boosterism and opposition to labor unions, the latter of which led to the bombing of its headquarters in 1910. The paper's profile grew substantially in the 1960s under publisher Otis Chandler, who adopted a more national focus. In recent decades the paper's readership has declined, and it has been beset by a series of ownership changes, staff reductions, and other controversies. In January 2018, the paper's staff voted to unionize ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maximum Take-off Weight
The maximum takeoff weight (MTOW) or maximum gross takeoff weight (MGTOW) or maximum takeoff mass (MTOM) of an aircraft is the maximum weight at which the pilot is allowed to attempt to take off, due to structural or other limits. The analogous term for rockets is gross lift-off mass, or GLOW. MTOW is usually specified in units of kilograms or pounds. MTOW is the heaviest weight at which the aircraft has been shown to meet all the airworthiness requirements applicable to it. MTOW of an aircraft is fixed and does not vary with altitude, air temperature, or the length of the runway to be used for takeoff or landing. Maximum permissible takeoff weight or "regulated takeoff weight", varies according to flap setting, altitude, air temperature, length of runway and other factors. It is different from one takeoff to the next, but can never be higher than the MTOW. Certification standards Certification standards applicable to the airworthiness of an aircraft contain many requirement ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NASA
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station.
