People's Liberation Army Naval Air Force
The People's Liberation Army Naval Air Force (PLANAF; ) is the naval aviation branch of the People's Liberation Army Navy. Overview Historically, the PLANAF's main role has been to provide the navy's warships with air defense coverage. Part of the coastal defense doctrine was to have naval aircraft protecting the ships, hence the reason why many PLA ships of the 1960s–70s lacked long range anti-aircraft missiles or artillery. During the Sino-Vietnamese War, the PLANAF carried out many successful bombing and airstrike missions against Vietnamese territories, such as in the Spratly Islands. The 1960s saw a series of air combat sorties flown against the Republic of China Air Force. PLANAF pilots have been credited with many major victories over the Taiwanese in these small incidents. Historical aircraft operated by the PLANAF include the J-5, the J-6, and H-5. These aircraft have been retired by the late 1990s. Today, the PLANAF has a strength of around 26,000 personnel and ...

People's Liberation Army Air Force
The People's Liberation Army Air Force (PLAAF; ), also known as the Chinese Air Force (中国空军) or the People's Air Force (人民空军), is an aerial service branch of the People's Liberation Army, the regular armed forces of the People's Republic of China. The PLAAF was officially established on 11 November 1949 and it is composed of 5 branches which are aviation, anti-aircraft artillery, surface-to-air missiles (SAM), radar, and Airborne Corps. The PLAAF first faced combat in the Korean War against the United States using primarily the Mikoyan-Gurevich MiG-15 fighter aircraft, aircraft provided by the Soviet Union, which also assisted with the expansion of the Chinese aerospace industry. Changes in the organization of the PLAAF followed by modernization programs in the 1990s and increased technology development in the 21st century has created the J-20 stealth multirole fighter, the first of its kind for China.

Rolls-Royce Spey
The Rolls-Royce Spey (company designations RB.163 and RB.168 and RB.183) is a low-bypass turbofan engine originally designed and manufactured by Rolls-Royce that has been in widespread service for over 40 years. A co-development version of the Spey between Rolls-Royce and Allison in the 1960s is the Allison TF41. Intended for the civilian jet airliner market when it was being designed in the late 1950s, the Spey concept was also used in various military engines, and later as a turboshaft engine for ships known as the Marine Spey, and even as the basis for a new civilian line, the Rolls-Royce RB.183 Tay. Aviation versions of the base model Spey have accumulated over 50 million hours of flight time. In keeping with Rolls-Royce naming practices, the engine is named after the River Spey. Design and development In 1954 Rolls-Royce introduced the first commercial bypass engine, the Rolls-Royce Conway, with 17,500 lbf (78 kN) of thrust aimed at what was then the "large end" o ...

People's Liberation Army Navy
The People's Liberation Army Navy (PLAN; ), also known as the People's Navy, Chinese Navy, or PLA Navy, is the maritime service branch of the People's Liberation Army. The PLAN traces its lineage to naval units fighting during the Chinese Civil War and was established on 23 April 1949. Throughout the 1950s and early 1960s, the Soviet Union provided assistance to the PLAN in the form of naval advisers and export of equipment and technology. Until the late 1980s, the PLAN was largely a riverine and littoral force (brown-water navy). In the 1990s, following the fall of the Soviet Union and a shift towards a more forward-oriented foreign and security policy, the leaders of the Chinese military were freed from worrying overland border disputes. Traditionally subordinated to the PLA Ground Force, PLAN leaders were now able to advocate for a renewed attention towards the seas. Chinese military officials have outlined plans to operate in the first and second island chains, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nanchang Q-5
The Nanchang Q-5 (; NATO reporting name: Fantan), also known as the A-5 in its export versions, is a Chinese-built single-seat, twin jet engine ground-attack aircraft based on the Shenyang J-6. The aircraft is primarily used for close air support. Design and development The PRC was an enthusiastic user of the MiG-19, which it manufactured locally as the Shenyang J-6 from 1958. In August 1958, the People's Liberation Army requested development of a jet attack aircraft for the air support role. Lu Xiaopeng was appointed chief designer of this project. Lu also designed the J-12 fighter jet. Although based on the MiG-19, the new design, designated Qiangjiji-5 (fifth attack aircraft design), had a longer fuselage, area ruled to reduce transonic drag and accommodate a 4 m (13-ft) long internal weapons bay. The air intakes were moved to the fuselage sides to make space in the nose for a planned target radar (which was never actually fitted). New wings with greater area and reduc ...

China Aviation Industry Corporation I
China Aviation Industry Corporation I (AVIC I) was a Chinese consortium of aircraft manufacturers. The consortium was created on 1 July 1999 by splitting the state-owned consortium Aviation Industry Corporation of China (AVIC) into AVIC I and AVIC II. AVIC I was historically focused on large planes such as bombers (Xian H-6, Xian JH-7), medium commercial planes (ARJ21), or fighter planes ( J-7, J-8, J-10, J-11 and JF-17), while AVIC II was focused on smaller planes and helicopters. On 28 October 2008, the companies officially consolidated back into one organization to more efficiently manage resources and avoid redundant projects.

Terrain-following Radar
Terrain-following radar (TFR) is a military aerospace technology that allows a very-low-flying aircraft to automatically maintain a relatively constant altitude above ground level and therefore make detection by enemy radar more difficult. It is sometimes referred to as ''ground hugging'' or ''terrain hugging'' flight. The term ''nap-of-the-earth'' flight may also apply but is more commonly used in relation to low-flying military helicopters, which typically do not use terrain-following radar. TFR systems work by scanning a radar beam vertically in front of the aircraft and comparing the range and angle of the radar reflections to a pre-computed ideal manoeuvring curve. By comparing the distance between the terrain and the ideal curve, the system calculates a manoeuvre that will make the aircraft clear the terrain by a pre-selected distance, often on the order of . Using TFR allows an aircraft to automatically follow terrain at very low levels and high speeds. Terrain-following r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Dynamics F-111
The General Dynamics F-111 Aardvark is a retired supersonic, medium-range, multirole combat aircraft. Production variants of the F-111 had roles that included ground attack (e.g. interdiction), strategic bombing (including nuclear weapons capabilities), reconnaissance and electronic warfare. Developed in the 1960s by General Dynamics, the F-111 entered service in 1967 with the United States Air Force (USAF). The Royal Australian Air Force (RAAF) also ordered the type and began operating the F-111C variant in 1973. The F-111 pioneered several technologies for production aircraft, including variable-sweep wings, afterburning turbofan engines, and automated terrain-following radar for low-level, high-speed flight. Its design influenced later variable-sweep wing aircraft, and some of its advanced features have since become commonplace. The F-111 suffered a variety of problems during initial development. A fighter variant, the F-111B, was not accepted for production. The F-1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prototype
A prototype is an early sample, model, or release of a product built to test a concept or process. It is a term used in a variety of contexts, including semantics, design, electronics, and Software prototyping, software programming. A prototype is generally used to evaluate a new design to enhance precision by system analysts and users. Prototyping serves to provide specifications for a real, working system rather than a theoretical one. In some design workflow models, creating a prototype (a process sometimes called materialization) is the step between the Formal specification, formalization and the evaluation of an idea. A prototype can also mean a typical example of something such as in the use of the derivation 'prototypical'. This is a useful term in identifying objects, behaviours and concepts which are considered the accepted norm and is analogous with terms such as stereotypes and archetypes. The word ''wikt:prototype, prototype'' derives from the Greek language, Greek ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
