Aerostructures
An aerostructure is a component of an aircraft's airframe. This may include all or part of the fuselage, wings, or flight control surfaces. Companies that specialize in constructing these components are referred to as "aerostructures manufacturers", though many larger aerospace firms with a more diversified product portfolio also build aerostructures. Mechanical testing of the individual components or complete structure is carried out on a Universal Testing Machine. Test carried out include tensile, compression, flexure, fatigue, impact, compression after impact. Before testing the componentaerospace engineersbuild finite element models to simulate the reality. Civilian Airplanes designed for civilian use are often cheaper than military aircraft. Smaller passenger airplanes are used for short distance, transcontinental transport. It is more cost efficient for airlines and there is less demand for aircraft transportation at these distances as people can, while inconvenient, dri ...

Boeing Defense, Space & Security retained its military business in Wichita, which lay on neighboring land, until Boeing sold most of those properties to Air Capital Flight Line. The Wichita division was responsible for construction of many important aircraft in Boeing's history, includi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aero Vodochody
Aero Vodochody (commonly referred to as Aero) is a Czech aircraft company. Its main production facilities are located at Vodochody Airport in the Prague-East District, on the municipal territories of Vodochody and Odolena Voda. During the Cold War era, the firm was well known for its range of jet-powered trainer aircraft, the L-29 Delfin and L-39 Albatros. It also developed derivatives of the L-39, the L-59 Super Albatros and the L-159 Alca military light combat jet. Aero Vodochody is believed to have handled the biggest aircraft industrial programme to take place across any of the Council for Mutual Economic Assistance (COMECON) countries except for the Soviet Union itself. Following the fall of the communist government in Czechoslovakia during 1989, Aero Vodochody experienced a disruptive period of business, having lost a major portion of the market for its jet trainers. Sales noticeably declined during the 1990s in Eastern Europe as well as in NATO countries as a resul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stelia Aerospace
Stelia Aerospace (stylized STELIA Aerospace) is an aerospace company headquartered in Toulouse, France. It specializes in the design and manufacture of aerostructures, pilot seats and premium class passenger seats, mainly for the commercial aviation sector. Stelia Aerospace was created on 1 January 2015 by the merger of two Airbus business units: ''Aerolia'' and ''SOGERMA''. The company is a wholly owned subsidiary of Airbus.

Vought
Vought was the name of several related American aerospace firms. These have included, in the past, Lewis and Vought Corporation, Chance Vought, Vought-Sikorsky, LTV Aerospace (part of Ling-Temco-Vought), Vought Aircraft Companies, and Vought Aircraft Industries. The first incarnation of Vought was established by Chance M. Vought and Birdseye Lewis in 1917. In 1928, it was acquired by United Aircraft and Transport Corporation, which a few years later became United Aircraft Corporation; this was the first of many reorganizations and buyouts. During the 1920s and 1930s, Vought Aircraft and Chance Vought specialized in carrier-based aircraft for the United States Navy, by far its biggest customer. Chance Vought produced thousands of planes during World War II, including the F4U Corsair. Vought became independent again in 1954, and was purchased by Ling-Temco-Vought (LTV) in 1961. The company designed and produced a variety of planes and missiles throughout the Cold War. Vought wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Design
A design is a plan or specification for the construction of an object or system or for the implementation of an activity or process or the result of that plan or specification in the form of a prototype, product, or process. The verb ''to design'' expresses the process of developing a design. In some cases, the direct construction of an object without an explicit prior plan (such as in craftwork, some engineering, coding, and graphic design) may also be considered to be a design activity. The design usually has to satisfy certain goals and constraints; may take into account aesthetic, functional, economic, or socio-political considerations; and is expected to interact with a certain Environment (systems), environment. Typical examples of designs include architectural drawing, architectural and engineering drawing, engineering drawings, circuit diagrams, Pattern (sewing), sewing patterns and less tangible artefacts such as business process models. Designing People who produce designs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wing
A wing is a type of fin that produces lift while moving through air or some other fluid. Accordingly, wings have streamlined cross-sections that are subject to aerodynamic forces and act as airfoils. A wing's aerodynamic efficiency is expressed as its lift-to-drag ratio. The lift a wing generates at a given speed and angle of attack can be one to two orders of magnitude greater than the total drag on the wing. A high lift-to-drag ratio requires a significantly smaller thrust to propel the wings through the air at sufficient lift. Lifting structures used in water include various foils, such as hydrofoils. Hydrodynamics is the governing science, rather than aerodynamics. Applications of underwater foils occur in hydroplanes, sailboats and submarines. Etymology and usage For many centuries, the word "wing", from the Old Norse ''vængr'', referred mainly to the foremost limbs of birds (in addition to the architectural aisle). But in recent centuries the word's meaning has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Universal Testing Machine
A universal testing machine (UTM), also known as a universal tester, materials testing machine or materials test frame, is used to test the tensile strength and compressive strength of materials. An earlier name for a tensile testing machine is a tensometer. The "universal" part of the name reflects that it can perform many standard tensile and compression tests on materials, components, and structures (in other words, that it is versatile). Components Several variations are in use. Common components include: * Load frame - Usually consisting of two strong supports for the machine. Some small machines have a single support. * Load cell - A force transducer or other means of measuring the load is required. Periodic calibration is usually required by governing regulations or quality system. * Cross head - A movable cross head (crosshead) is controlled to move up or down. Usually this is at a constant speed: sometimes called a ''constant rate of extension'' (CRE) machine. So ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Civilian
Civilians under international humanitarian law are "persons who are not members of the armed forces" and they are not "combatants if they carry arms openly and respect the laws and customs of war". It is slightly different from a non-combatant, because some non-combatants are not civilians (for example, military chaplains who are attached to the belligerent party or military personnel who are serving with a neutral country). Civilians in the territories of a party to an armed conflict are entitled to certain privileges under the customary laws of war and international treaties such as the Fourth Geneva Convention. The privileges that they enjoy under international law depends on whether the conflict is an internal one (a civil war) or an international one. In some nations, uniformed members of civilian police or fire departments colloquially refer to members of the public as civilians. Etymology The word "civilian" goes back to the late 14th century and is from Old French '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
