Xian JH-7
The Xi'an JH-7 ( zh, s=歼轰-7, t=殲轟-7, hp=jiān hōng qī – fighter-bomber; NATO reporting name Flounder), also known as the FBC-1 (Fighter/Bomber China-1) Flying Leopard, is a Chinese tandem two-seat, twin-engine fighter-bomber in service with the People's Liberation Army Naval Air Force (PLANAF), and the People's Liberation Army Air Force (PLAAF). The main contractors are Xi'an Aircraft Industrial Corporation (XAC) and the 603rd Aircraft Design Institute (later named the First Aircraft Institute of AVIC-I). The first JH-7s were delivered to the PLANAF in the mid-1990s for evaluation, with the improved JH-7A entering service in 2004. Development history A new fighter bomber In the early 1970s, the PLAAF required a new fighter-bomber to replace the Harbin H-5 and Nanchang Q-5. A request was duly submitted to the Ministry of Aviation Industry (later renamed to the Aviation Industry Corporation of China), which organized a domestic development program when efforts ...

Fighter-bomber
A fighter-bomber is a fighter aircraft that has been modified, or used primarily, as a light bomber or attack aircraft. It differs from bomber and attack aircraft primarily in its origins, as a fighter that has been adapted into other roles, whereas bombers and attack aircraft are developed specifically for bombing and attack roles. Although still used, the term fighter-bomber has less significance since the introduction of rockets and guided missiles into aerial warfare. Modern aircraft with similar duties are now typically called multirole combat aircraft or strike fighters. Development Prior to World War II, general limitations in available Aircraft engine, engine and Aerospace engineering, aeronautical technology required that each proposed military aircraft have its design tailored to a specific prescribed role. Reciprocating engine, Engine power grew dramatically during the early period of the war, roughly doubling between 1939 and 1943. The Bristol Blenheim, a typical ...

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 smaller 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 ...

Liquid Crystal Display
A liquid-crystal display (LCD) is a flat-panel display or other Electro-optic modulator, electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers to display information. Liquid crystals do not emit light directly but instead use a backlight or Reflector (photography), reflector to produce images in color or Monochrome monitor, monochrome. LCDs are available to display arbitrary images (as in a general-purpose computer display) or fixed images with low information content, which can be displayed or hidden: preset words, digits, and seven-segment displays (as in a digital clock) are all examples of devices with these displays. They use the same basic technology, except that arbitrary images are made from a matrix of small pixels, while other displays have larger elements. LCDs are used in a wide range of applications, including LCD televisions, computer monitors, Dashboard, instrument panels, flight instrument ...

Helmet-mounted Display
A helmet-mounted display (HMD) is a headworn device that uses displays and optics to project imagery and/or symbology to the eyes. It provides visual information to the user where head protection is required – most notably in military aircraft. The display-optics assembly can be attached to a helmet or integrated into the design of the helmet. An HMD provides the pilot with situation awareness, an enhanced image of the scene, and in military applications cue weapons systems, to the direction their head is pointing. Applications which allow cuing of weapon systems are referred to as helmet-mounted sight and display (HMSD) or helmet-mounted sights (HMS). Requirement Aviation HMD designs serve these purposes: * using the head angle as a pointer to direct air-to-air and air-to-ground weapons seekers or other sensors (e.g., radar, FLIR) to a target by the pilot merely turning the helmet towards the target and operating a switch via HOTAS. In close combat, without HMDs, pilo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
YJ-8
The YJ-8 (; NATO reporting name: CSS-N-4 Sardine) is a Chinese air and surface-launched subsonic anti-ship cruise missile. It is manufactured by the China Aerospace Science and Industry Corporation (CASIC) Third Academy.Gromley et al.: page 101 The YJ-8 was developed into air-launched (YJ-81) and submarine-launched ( YJ-82) variants. Description The YJ-8 is either based on, or is a heavily modified copy of, the MM38 Exocet; the two missiles share virtually identical operational profiles. The replication of the MM38's "revolutionary flight profile" in less than ten years and with an immature industrial base strongly suggests that China had access to proven technology. The YJ-8 was a "radical departure" from China's first anti-ship missiles derived from the P-15 Termit. The YJ-8 carried a smaller warhead, but had the same range and speed while being significantly smaller and lighter. Development The development of the YJ-8 was approved in late-1976 following a few years of enco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Precision-guided Munition
A precision-guided munition (PGM), also called a smart weapon, smart munition, or smart bomb, is a type of weapon system that integrates advanced guidance and control systems, such as Global Positioning System, GPS, laser guidance, or Infrared search and track, infrared sensors, with various types of Ammunition, munitions, typically Missile, missiles or Shell (projectile), artillery shells, to allow for high-accuracy strikes against designated Targeting (warfare), targets. PGMs are designed to precisely hit a predetermined target, typically with a margin of error (or circular error probable, CEP) that is far smaller than conventional unguided munitions. Unlike unguided munitions, PGMs use active or passive Control system, control mechanisms capable of steering the weapon towards its intended target. PGMs are capable of mid-flight course corrections, allowing them to adjust and hit the intended target even if conditions change. PGMs can be deployed from various platforms, includi ...

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. Physical prototyping has a long history, and paper prototyping and virtual prototyping now extensively complement it. 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 ...
