SAAB 2000
The Saab 2000 is a twin-engined high-speed turboprop airliner built by Swedish aircraft manufacturer Saab. It is designed to carry 50–58 passengers and cruise at a speed of . Production took place in Linköping in southern Sweden. The Saab 2000 first flew in March 1992 and was certified in 1994. The last aircraft was delivered in April 1999, a total of 63 aircraft being built. By October 2022, 27 Saab 2000s were in airline and military service. Development and design In December 1988, Saab decided to build a stretched derivative of its successful Saab 340 twin-turboprop regional airliner. The new aircraft was planned to meet a perceived demand for a high-speed 50-seat turboprop with good climb performance which could operate over short- and medium-range routes with similar block times to jet aircraft while retaining the efficiency provided by turboprop engines. The new airliner, called the Saab 2000, was formally launched in May 1989, with Saab already having firm orders ... [...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".

Option (aircraft Purchasing)
An ''option'', when purchasing aircraft, allows an airline An airline is a company that provides civil aviation, air transport services for traveling passengers and freight. Airlines use aircraft to supply these services and may form partnerships or Airline alliance, alliances with other airlines for ... to purchase additional aircraft in the future at an agreed price and date. When placing orders for new aircraft, airlines commonly obtain ''options'' from the aircraft manufacturer. These options allow the airline to delay the purchase of additional aircraft until market conditions become clearer and the purchase can be justified. It also reserves the airline a place in the manufacturing queue, for a guaranteed delivery slot. When the airline finally exercises its options, it can place its order without having to join the end of the queue which otherwise may delay the delivery of the aircraft for years. If future conditions do not justify expansion of the airline's fleet, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dowty Rotol
Dowty Propellers is a British engineering company based in Brockworth, Gloucestershire that specialises in the manufacture, repair and overhaul of propellers and propeller components for customers around the world. It is owned by General Electric, forming part of its GE Aviation Systems division. History The company was formed as Rotol Airscrews in 1937 by Rolls-Royce and Bristol Engines to take over both companies' propeller development, the market being too small to support more than one company. The name is a contraction of "ROlls-Royce" and "BrisTOL". Rotol's propellers were always considered leading edge, its models equipping the Hawker Hurricane, Supermarine Spitfire, and many other Second World War-era aircraft. By the end of the war it had introduced the first five-bladed propeller to see widespread use, used on late-model Spitfires. In 1943 the company changed its name from Rotol Airscrews Limited to Rotol Limited, and in 1952 it acquired British Messier Limited, a ...

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 Geo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Institute Of Aeronautics And Astronautics
The American Institute of Aeronautics and Astronautics (AIAA) is a professional society for the field of aerospace engineering. The AIAA is the U.S. representative on the International Astronautical Federation and the International Council of the Aeronautical Sciences. In 2015, it had more than 30,000 members among aerospace professionals worldwide (a majority are American and/or live in the United States). History The AIAA was founded in 1963 from the merger of two earlier societies: the American Rocket Society (ARS), founded in 1930 as the American Interplanetary Society (AIS), and the Institute of the Aerospace Sciences (IAS), founded in 1932 as the Institute of the Aeronautical Sciences. Paul Johnston was the first executive director of the organization. Jim Harford took his seat after 18 months. The newly-formed structure gathered 47 technical committees and one broad technical publication, the ''AIAA Journal''. The ''AIAA Student Journal'' was also launched in 1963. T ...

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 anima ...

Joint Aviation Authorities
The Joint Aviation Authorities (JAA) was an associated body of the European Civil Aviation Conference representing the civil aviation regulatory authorities of a number of European States who had agreed to co-operate in developing and implementing common safety regulatory standards and procedures. It was not a regulatory body, regulation being achieved through the member authorities. It was in existence from 1970 until disbanded in 2009. Its headquarters were located in Hoofddorp near Schiphol airport in Netherlands. JAA issued the Joint Aviation Requirements (JAR), intended to establish minimum requirements for air safety. In implementing the so-called FUJA Report, the JAA had entered into a new phase as of 1 January 2007. In this new phase the former "JAA" had become "JAA T" (Transition). JAA T consisted of a Liaison Office (JAA LO) and a Training Office (JAA TO). The offices of JAA LO were located in the premises of European Aviation Safety Agency (E ...
