F-7 Skybolt
The Chengdu J-7 ( Chinese: 歼-7; third generation export version F-7; NATO reporting name: Fishcan) is a Chinese fighter aircraft. It is a license-built version of the Soviet Mikoyan-Gurevich MiG-21, and thus shares many similarities with that aircraft. The aircraft is armed with short-range, infrared homing air-to-air missiles and is mainly designed for short range air-to-air combat. The aircraft is also used for close air support. On 30 March 1962, the Soviet Union and China signed a technology transference arrangement pertaining to the MiG-21. Allegedly, while various kits, components, completed aircraft and associated documents were delivered to the Shenyang Aircraft Factory, the design documentation was incomplete, and Chinese designers made efforts to reverse engineer the aircraft. While the two aircraft are greatly similar, areas of difference include the hydraulic systems and internal fuel arrangements. During March 1964, domestic production of the J-7 reportedly com ...

Aircraft
An aircraft ( aircraft) is a vehicle that is able to flight, fly by gaining support from the Atmosphere of Earth, air. It counters the force of gravity by using either Buoyancy, static lift or the Lift (force), dynamic lift of an airfoil, or, in a few cases, direct Powered lift, downward thrust from its engines. Common examples of aircraft include airplanes, rotorcraft (including helicopters), airships (including blimps), Glider (aircraft), gliders, Powered paragliding, paramotors, and hot air balloons. Part 1 (Definitions and Abbreviations) of Subchapter A of Chapter I of Title 14 of the U. S. Code of Federal Regulations states that aircraft "means a device that is used or intended to be used for flight in the air." The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Aircrew, Crewed aircraft are flown by an onboard Aircraft pilot, pilot, whereas unmanned aerial vehicles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shenyang J-8
The Shenyang J-8 (Simplified Chinese characters, Chinese: 歼-8; NATO reporting name: Finback) is a family of interceptor aircraft developed by the Shenyang Aircraft Design Institute, 601 Institute (Shenyang) in the People's Republic of China (PRC). It was conceived in the early 1960s as a low-risk program based on enlarging the Mikoyan-Gurevich MiG-21F, a version of which the PRC was producing as the Chengdu J-7. The original J-8 experienced protracted development due to disruption from the Cultural Revolution; the prototypes first flew in 1969 but the design was not finalized until 1979 with the aircraft entering service in 1980. The J-8II/J-8B (NATO reporting name: Finback-B) was a major development of the J-8 and was essentially a new aircraft. The J-8II replaced the distinctive nose air intake with a conventional radome and side air intakes to create room for a modern fire-control radar, and used more powerful engines. The aircraft started development in 1982, and was clear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avionics
Avionics (a portmanteau of ''aviation'' and ''electronics'') are the Electronics, electronic systems used on aircraft. Avionic systems include communications, Air navigation, navigation, the display and management of multiple systems, and the hundreds of systems that are fitted to aircraft to perform individual functions. These can be as simple as a searchlight for a police helicopter or as complicated as the tactical system for an airborne early warning platform. History The term "avionics" was coined in 1949 by Philip J. Klass, senior editor at ''Aviation Week & Space Technology'' magazine as a portmanteau of "aviation electronics". Radio communication was first used in aircraft just prior to World War I. The first Airborne radio relay, airborne radios were in zeppelins, but the military sparked development of light radio sets that could be carried by heavier-than-air craft, so that aerial reconnaissance biplanes could report their observations immediately in case they we ...

The Cultural Revolution
The Cultural Revolution, formally known as the Great Proletarian Cultural Revolution, was a Social movement, sociopolitical movement in the China, People's Republic of China (PRC). It was launched by Mao Zedong in 1966 and lasted until his death in 1976. Its stated goal was to preserve Ideology of the Chinese Communist Party, Chinese socialism by purging remnants of Capitalism, capitalist and Four Olds, traditional elements from Chinese culture, Chinese society. In May 1966, with the help of the Cultural Revolution Group, Mao launched the Revolution and said that Bourgeoisie, bourgeois elements had infiltrated the government and society with the aim of restoring capitalism. Mao called on young people to Bombard the Headquarters, bombard the headquarters, and proclaimed that "to rebel is justified". Mass upheaval began in Beijing with Red August in 1966. Many young people, mainly students, responded by forming Cadre system of the Chinese Communist Party, cadres of Red Guards th ...

Hydraulic
Hydraulics () is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids. At a very basic level, hydraulics is the liquid counterpart of pneumatics, which concerns gases. Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on applied engineering using the properties of fluids. In its fluid power applications, hydraulics is used for the generation, control, and transmission of Power (physics), power by the use of pressure, pressurized liquids. Hydraulic topics range through some parts of science and most of engineering modules, and they cover concepts such as pipe Volumetric flow rate, flow, dam design, fluidics, and fluid control circuitry. The principles of hydraulics are in use naturally in the human body within the vascular system and erectile tissue. ''Free surface hydraulics'' is the branch of hydraulics dealing with free surface flow, such as occurring in rivers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reverse Engineering
Reverse engineering (also known as backwards engineering or back engineering) is a process or method through which one attempts to understand through deductive reasoning how a previously made device, process, system, or piece of software accomplishes a task with very little (if any) insight into exactly how it does so. Depending on the system under consideration and the technologies employed, the knowledge gained during reverse engineering can help with repurposing obsolete objects, doing security analysis, or learning how something works. Although the process is specific to the object on which it is being performed, all reverse engineering processes consist of three basic steps: information extraction, modeling, and review. Information extraction is the practice of gathering all relevant information for performing the operation. Modeling is the practice of combining the gathered information into an abstract model, which can be used as a guide for designing the new object or syst ...

Documentation
Documentation is any communicable material that is used to describe, explain or instruct regarding some attributes of an object, system or procedure, such as its parts, assembly, installation, maintenance, and use. As a form of knowledge management and knowledge organization, documentation can be provided on paper, online, or on digital or analog media, such as audio tape or CDs. Examples are user guides, white papers, online help, and quick-reference guides. Paper or hard-copy documentation has become less common. Documentation is often distributed via websites, software products, and other online applications. Documentation as a set of instructional materials shouldn't be confused with documentation science, the study of the recording and retrieval of information. Principles for producing documentation While associated International Organization for Standardization (ISO) standards are not easily available publicly, a guide from other sources for this topic may serve ...

Technology Transfer
Technology transfer (TT), also called transfer of technology (TOT), is the process of transferring (disseminating) technology from the person or organization that owns or holds it to another person or organization, in an attempt to transform inventions and scientific outcomes into new products and services that benefit society. Technology transfer is closely related to (and may arguably be considered a subset of) knowledge transfer. A comprehensive definition of technology transfer today includes the notion of collaborative process as it became clear that global challenges could be resolved only through the development of global solutions. Knowledge and technology transfer plays a crucial role in connecting innovation stakeholders and moving inventions from creators to public and private users. Intellectual property (IP) is an important instrument of technology transfer, as it establishes an environment conducive to sharing research results and technologies. Analysis in 2003 showe ...
