Stewart Platform
A Stewart platform is a type of parallel manipulator that has six prismatic actuators, commonly hydraulic jacks or electric linear actuators, attached in pairs to three positions on the platform's baseplate, crossing over to three mounting points on a top plate. All 12 connections are made via universal joints. Devices placed on the top plate can be moved in the six degrees of freedom in which it is possible for a freely-suspended body to move: three linear movements x, y, z (lateral, longitudinal, and vertical), and the three rotations (pitch, roll, and yaw). Stewart platforms are known by various other names. In many applications, including in flight simulators, it is commonly referred to as a motion base. It is sometimes called a ''six-axis platform'' or ''6-DoF platform'' because of its possible motions and, because the motions are produced by a combination of movements of multiple actuators, it may be referred to as a ''synergistic motion platform'', due to the synergy (m ...

Animatronics
Animatronics refers to mechatronic puppets. They are a modern variant of the automaton and are often used for the portrayal of characters in films and in theme park attractions. It is a multidisciplinary field integrating puppetry, anatomy and mechatronics. Animatronic figures can be implemented with both computer and human control, including teleoperation. Motion actuators are often used to imitate muscle movements and create realistic motions. Figures are usually encased in body shells and flexible skins made of hard and soft plastic materials and finished with colors, hair, feathers and other components to make them more lifelike. Animatronics stem from a long tradition of mechanical automata powered by hydraulics, pneumatics and clockwork. Greek mythology and ancient Chinese writings mention early examples of automata. The oldest extant automaton is dated to the 16th century. Before the term "animatronics" became common, they were usually referred to as "robots". Since t ...

Lockheed C-130 Hercules
The Lockheed C-130 Hercules is an American four-engine turboprop military transport aircraft designed and built by Lockheed (now Lockheed Martin). Capable of using unprepared runways for takeoffs and landings, the C-130 was originally designed as a troop, medevac, and cargo transport aircraft. The versatile airframe has found uses in other roles, including as a gunship (AC-130), for airborne assault, search and rescue, scientific research support, weather reconnaissance, aerial refueling, maritime patrol, and aerial firefighting. It is now the main tactical airlifter for many military forces worldwide. More than 40 variants of the Hercules, including civilian versions marketed as the Lockheed L-100, operate in more than 60 nations. The C-130 entered service with the U.S. in 1956, followed by Australia and many other nations. During its years of service, the Hercules has participated in numerous military, civilian and humanitarian aid operations. In 2007, the C-130 became ...

Convair 990 Coronado
The Convair 990 Coronado is an American narrow-body four-engined jet airliner produced between 1961 and 1963 by the Convair division of American company General Dynamics. It was a stretched version of its earlier Convair 880 produced in response to a request from American Airlines: the 990 was lengthened by , which increased the number of passengers from between 88 and 110 in the 880 to between 96 and 121. This was still fewer passengers than the contemporary Boeing 707 (110 to 189) or Douglas DC-8 (105 to 173), although the 990 was faster than either in cruise. Design and development American Airlines asked Convair to design an aircraft for coast-to-coast flights, able to fly nonstop from New York City to Los Angeles against the wind. They wanted a larger passenger capacity than the 880, which was the smallest of the first-generation U.S. jet airliners. It was known as the Convair 600 and was redesignated the Convair 990 in the month of its first flight. The 990 began flight ...

Vickers Vanguard
The Vickers Vanguard was a short/medium-range turboprop airliner designed and produced by the British aircraft manufacturer Vickers-Armstrongs. The Vanguard was developed during the mid-to-late 1950s in response to a specification issued by British European Airways (BEA) for a 100 seat airliner; Vickers decided to design such an airliner as a follow-up to the existing Viscount series, the principal difference from which being an expanded airframe that provided considerably more internal volume. Another key innovation was the Tyne engine, which was roughly twice as powerful as the Viscount's Rolls-Royce Dart engine, and allowed for increases in both cruising speed and altitude. Throughout the design process, the needs of two airlines, BEA and Trans-Canada Air Lines (TCA), heavily shaped the Vanguard's specifics. The Vanguard was brought into revenue service on 17 December 1960, around the same time as the commercial availability of a new generation of jet-powered airliners; a ...

Vickers Viscount
The Vickers Viscount is a British medium-range turboprop airliner first flown in 1948 by Vickers-Armstrongs. A design requirement from the Brabazon Committee, it entered service in 1953 and was the first turboprop-powered airliner. The Viscount was well received by the public for its cabin conditions, which included pressurisation, reductions in vibration and noise, and panoramic windows. It became one of the most successful and profitable of the first post-war transport aircraft; 445 Viscounts were built for a range of international customers, including in North America. Development Origins The Viscount was a response to the 1943 Brabazon Committee's proposed Type II design for a post-war small medium-range pressurised aircraft to fly less-travelled routes, carrying 24 passengers up to 1,750 mi (2,816 km) at 200 mph (320 km/h).Cacutt 1989, pp. 323–333.

Boeing 727
The Boeing 727 is an American narrow-body airliner that was developed and produced by Boeing Commercial Airplanes. After the heavy 707 quad-jet was introduced in 1958, Boeing addressed the demand for shorter flight lengths from smaller airports. On December 5, 1960, the 727 was launched with 40 orders each from United Airlines and Eastern Air Lines. The first 727-100 rolled out November 27, 1962, first flew on February 9, 1963, and entered service with Eastern on February 1, 1964. The only trijet aircraft to be produced by Boeing, the 727 is powered by Pratt & Whitney JT8D low-bypass turbofans below a T-tail, one on each side of the rear fuselage and a center one fed through an S-duct. It shares its six-abreast upper fuselage cross-section and cockpit with the 707. The long 727-100 typically carries 106 passengers in two classes over , or 129 in a single class. Launched in 1965, the stretched 727-200 flew in July 1967 and entered service with Northeast Airlines that Decem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canadair CL-44
The Canadair CL-44 was a Canadian turboprop airliner and cargo aircraft based on the Bristol Britannia that was developed and produced by Canadair in the late 1950s and early 1960s. Although innovative, only a small number of the aircraft were produced for the Royal Canadian Air Force (RCAF) (as the CC-106 Yukon), and for commercial operators worldwide. The aircraft is named after the Canadian territory of Yukon. Design and development In the 1950s, Canadair acquired a licence to build the Bristol Britannia airliner. Their first use of it was to build the heavily modified Canadair CL-28 Argus patrol aircraft (RCAF designation CP-107) that combined the Britannia's wings and tail sections with a new fuselage and engines. The resulting aircraft had lower speed and service ceiling, but it had two bomb bays and greatly extended loiter times. The RCAF required a replacement for its C-54GM North Star, itself an extensive redesign of the Douglas C-54 Skymaster. Among many changes, t ...

Sud Aviation Caravelle
The Sud Aviation SE 210 Caravelle is a French jet airliner produced by Sud Aviation. It was developed by SNCASE in the early 1950s and made its maiden flight on 27 May 1955. It included some de Havilland designs and components developed for the de Havilland Comet. SNCASE merged into the larger Sud Aviation conglomerate before the aircraft entered revenue service on 26 April 1959 with Scandinavian Airlines System (SAS); 282 were built until production ended in 1972. It was ordered by airlines on every continent and operated until its retirement in 2005. The short-range, five-abreast airliner is powered by two aft-mounted Rolls-Royce Avon turbojet engines, allowing a clean low wing. The configuration was later retained in many narrow-body aircraft and regional jets. The initial I, III and VI variants could seat 90 to 99 passengers over . The later, slightly longer 10/11 variants could seat 99 to 118 passengers over and were powered by Pratt & Whitney JT8D low-bypass turbofan ...

Full Flight Simulator
Full flight simulator (FFS) is a term used by national (civil) aviation authorities (NAA) for a high technical level of flight simulator. Such authorities include the Federal Aviation Administration (FAA) in the United States and the European Aviation Safety Agency (EASA). There are currently four levels of full flight simulator, levels A through D, with level D being the highest standard and being eligible for zero flight time (ZFT) training of civil pilots when converting from one airliner type to another. In about 2012, these FFS levels will be changed as a result of work by an international working group chaired by the UK Royal Aeronautical Society Flight Simulation Group (RAeS FSG), which rationalised 27 previous categories of flight training device into 7 international ones. This work has been accepted by ICAO and is published under ICAO document 9625 Issue 3. The new Type 7 Full Flight Simulator will be the old Level D with enhancements in a number of areas including motio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flight Simulator
A flight simulator is a device that artificially re-creates aircraft flight and the environment in which it flies, for pilot training, design, or other purposes. It includes replicating the equations that govern how aircraft fly, how they react to applications of flight controls, the effects of other aircraft systems, and how the aircraft reacts to external factors such as air density, turbulence, wind shear, cloud, precipitation, etc. Flight simulation is used for a variety of reasons, including flight training (mainly of pilots), the design and development of the aircraft itself, and research into aircraft characteristics and control handling qualities. The term "flight simulator" may carry slightly different meaning in general language and technical documents. In past regulations it referred specifically to devices which can closely mimic the behavior of aircraft throughout various procedures and flight conditions. In more recent definitions, this has been named "full flig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
