Boeing 747-8
The Boeing 747-8 is a wide-body airliner formerly developed by Boeing Commercial Airplanes, and the largest variant of the 747. After introducing the 747-400, Boeing considered larger 747 versions as alternatives to the proposed double-deck Airbus A3XX, later developed as the A380. The stretched 747 Advanced was launched as the on November 14, 2005, for a market forecast of 300 aircraft. The first 747-8F Freighter performed its maiden flight on February 8, 2010, and the passenger 747-8I Intercontinental followed suit on March 20, 2011. The cargo version was first delivered in October 2011 and the airliner began commercial service in June 2012. Its fuselage is stretched by to , making it the longest airliner until the 777X, which first flew in 2020. While keeping its basic structure and sweep, the wing is thicker and deeper, holding more fuel, and wider with raked wingtips. Powered more efficiently than preceding 747s by a smaller version of the General Electric GEnx tur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. Fo ...

Fuselage
The fuselage (; from the French ''fuselé'' "spindle-shaped") is an aircraft's main body section. It holds crew, passengers, or cargo. In single-engine aircraft, it will usually contain an engine as well, although in some amphibious aircraft the single engine is mounted on a pylon attached to the fuselage, which in turn is used as a floating hull. The fuselage also serves to position the control and stabilization surfaces in specific relationships to lifting surfaces, which is required for aircraft stability and maneuverability. Types of structures Truss structure This type of structure is still in use in many lightweight aircraft using welded steel tube trusses. A box truss fuselage structure can also be built out of wood—often covered with plywood. Simple box structures may be rounded by the addition of supported lightweight stringers, allowing the fabric covering to form a more aerodynamic shape, or one more pleasing to the eye. Geodesic construction Geod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft Noise
Aircraft noise pollution refers to noise produced by aircraft in flight that has been associated with several negative stress-mediated health effects, from sleep disorders to cardiovascular ones. Governments have enacted extensive controls that apply to aircraft designers, manufacturers, and operators, resulting in improved procedures and cuts in pollution. Sound production is divided into three categories: * Mechanical noise—rotation of the engine parts, most noticeable when fan blades reach supersonic speeds. * Aerodynamic noise—from the airflow around the surfaces of the aircraft, especially when flying low at high speeds. * Noise from aircraft systems—cockpit and cabin pressurization and conditioning systems, and Auxiliary Power units. Mechanisms of sound production Aircraft noise is noise pollution produced by an aircraft or its components, whether on the ground while parked such as auxiliary power units, while taxiing, on run-up from propeller and jet exhaust, duri ...

Fuel Efficiency
Fuel efficiency is a form of thermal efficiency, meaning the ratio of effort to result of a process that converts chemical potential energy contained in a carrier (fuel) into kinetic energy or work. Overall fuel efficiency may vary per device, which in turn may vary per application, and this spectrum of variance is often illustrated as a continuous energy profile. Non-transportation applications, such as industry, benefit from increased fuel efficiency, especially fossil fuel power plants or industries dealing with combustion, such as ammonia production during the Haber process. In the context of transport, fuel economy is the energy efficiency of a particular vehicle, given as a ratio of distance traveled per unit of fuel consumed. It is dependent on several factors including engine efficiency, transmission design, and tire design. In most countries, using the metric system, fuel economy is stated as "fuel consumption" in liters per 100 kilometers (L/100 km) ...

Wingspan
The wingspan (or just span) of a bird or an airplane is the distance from one wingtip to the other wingtip. For example, the Boeing 777–200 has a wingspan of , and a wandering albatross (''Diomedea exulans'') caught in 1965 had a wingspan of , the official record for a living bird. The term wingspan, more technically extent, is also used for other winged animals such as pterosaurs, bats, insects, etc., and other aircraft such as ornithopters. In humans, the term wingspan also refers to the arm span, which is distance between the length from one end of an individual's arms (measured at the fingertips) to the other when raised parallel to the ground at shoulder height at a 90º angle. Former professional basketball player Manute Bol stood at and owned one of the largest wingspans at . Wingspan of aircraft The wingspan of an aircraft is always measured in a straight line, from wingtip to wingtip, independently of wing shape or sweep. Implications for aircraft design and a ...

Farnborough Airshow
The Farnborough Airshow, officially the Farnborough International Airshow, is a trade exhibition for the aerospace and defence industries, where civilian and military aircraft are demonstrated to potential customers and investors. Since its first show in 1948, Farnborough has seen the debut of many famous planes, including the Vickers VC10, Concorde, the Eurofighter, the Airbus A380, and the Lockheed Martin F-35 Lightning II. At the 1958 show, the RAF's Black Arrows executed a 22-plane formation loop, setting a world record. The international trade show is put together every two years by FIL Farnborough International Ltd. and runs for five days. Until 2020, the show ran for a full week with trade visitors attending on the first five days and the weekend reserved for the general public. Programming takes place at the Farnborough Airport, which lies roughly 50 kilometres south-west of London. Status The Farnborough International Airshow is the second-largest show of its kind a ...

Boeing New Large Airplane
The Boeing NLA, or New Large Airplane, was a 1990s concept for an all-new quadjet airliner in the 500+ seat market. Somewhat larger than the 747, this aircraft was similar in concept to the McDonnell Douglas MD-12 and later Airbus A380. In 1993, Boeing chose not to pursue development of this concept, focusing instead on the Boeing 747-500X and -600X, and then on the 747X and 747X Stretch, and subsequently on the Boeing 747-8. The project names for this aircraft were NLA and Boeing 763-246C. Specifications (NLA, as designed) Source: ''Seattle Post-Intelligencer'' History The Boeing New Large Airplane was one of several projects started by Boeing in the late 20th century as a way to compete with rival aircraft corporations like Airbus. The Airbus A380 project began to be publicized in 1990 in order to try and turn the commercial aviation market away from the then very prevalent Boeing 747. Boeing sought to combat this and began working up designs for the NLA at some point in the e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Comparison Of Boeing 747-400 And 747-500X
Comparison or comparing is the act of evaluating two or more things by determining the relevant, comparable characteristics of each thing, and then determining which characteristics of each are similar to the other, which are different, and to what degree. Where characteristics are different, the differences may then be evaluated to determine which thing is best suited for a particular purpose. The description of similarities and differences found between the two things is also called a comparison. Comparison can take many distinct forms, varying by field: To compare things, they must have characteristics that are similar enough in relevant ways to merit comparison. If two things are too different to compare in a useful way, an attempt to compare them is colloquially referred to in English as "comparing apples and oranges." Comparison is widely used in society, in science and in the arts. General usage Comparison is a natural activity, which even animals engage in when deci ...

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] |
