Xian Y-20
The Xi'an Y-20 Kunpeng () is a large military transport aircraft developed by the Xi'an Aircraft Industrial Corporation for the People's Republic of China (PRC). The aircraft is nicknamed "Chubby Girl" () in the Chinese aviation industry because its fuselage is much wider than aircraft previously developed in China. Development Images of the Y-20 prototype emerged at the end of 2012. The first flight occurred on 26 January 2013. In 2014, a report from the People's Liberation Army's National Defence University stated that the PRC's civil and military transport needed 400 Y-20s. In 2016, Zhu Qian of the Aviation Industry Corporation of China stated that more than a thousand were needed. The airlifter was developed into the Y-20U tanker variant to expand the PLAAF's aerial refueling capability beyond its existing limited and obsolescent Xian H-6U fleet. Evidence of the tanker variant emerged in 2018 with satellite images; its first flight occurred that year. They had begun p ...

Soloviev D-30
The Soloviev D-30 (now the Aviadvigatel PS-30) is a Soviet two-shaft low-bypass turbofan engine, officially referred to as a "bypass turbojet". It is probably the single most important turbofan engine developed in the Soviet Union. Development of the turbofan spurred numerous growth versions with increased fan diameter and modified component arrangements. Developed within an amazingly short period of time (about three years), the D-30 turned out to be one of the most reliable engines in the history of Soviet engine development, and it was recognized with the USSR State Prize. Design and development The original version of the Soloviev D-30 was developed specifically to power the Tupolev Tu-134 short-to-medium range jet airliner; however, it also served as a base for the development of a family of advanced engines. Engine development was started in the early 60s. Nevertheless, by 1966, the engine was put into serial production. The D-30 engine has a two-stage compression spool, a ...

Guilin
Guilin ( Standard Zhuang: ''Gveilinz''; alternatively romanized as Kweilin) is a prefecture-level city in the northeast of China's Guangxi Zhuang Autonomous Region. It is situated on the west bank of the Li River and borders Hunan to the north. Its name means "forest of sweet osmanthus", owing to the large number of fragrant sweet osmanthus trees located in the region. The city has long been renowned for its scenery of karst topography. Guilin is one of China's most popular tourist destinations, and the epithet "By water, by mountains, most lovely, Guilin" () is often associated with the city. The State Council of China has designated Guilin a National Famous Historical and Cultural City, doing so in the first edition of the list. History Before the Qin dynasty, Guilin region was settled by the Baiyue people. In 314 BC, a small settlement was established along the banks of the Li River.

Relay
A relay Electromechanical relay schematic showing a control coil, four pairs of normally open and one pair of normally closed contacts An automotive-style miniature relay with the dust cover taken off A relay is an electrically operated switch. It consists of a set of input terminals for a single or multiple control signals, and a set of operating contact terminals. The switch may have any number of contacts in multiple contact forms, such as make contacts, break contacts, or combinations thereof. Relays are used where it is necessary to control a circuit by an independent low-power signal, or where several circuits must be controlled by one signal. Relays were first used in long-distance telegraph circuits as signal repeaters: they refresh the signal coming in from one circuit by transmitting it on another circuit. Relays were used extensively in telephone exchanges and early computers to perform logical operations. The traditional form of a relay uses an electromagnet to c ...

Helmet-mounted Display
A helmet-mounted display (HMD) is a device used in aircraft to project information to the pilot's eyes. Its scope is similar to that of head-up displays (HUD) on an aircrew's visor or reticle. 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 merely by pointing his head at the target and actuating a switch via HOTAS controls. In close combat prior to HMDs, the pilot had to align the aircraft to shoot at a target. HMDs allow the pilot to simply point his head at a target, designate it to weapon and shoot. * displaying targeti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xian JH-7
The Xi'an JH-7 ( – fighter-bomber; NATO reporting name Flounder), also known as the FBC-1 (Fighter/Bomber China-1) Flying Leopard, is a 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 to secure a joint venture with foreign partners failed.

T-tail
A T-tail is an empennage configuration in which the tailplane is mounted to the top of the fin. The arrangement looks like the capital letter T, hence the name. The T-tail differs from the standard configuration in which the tailplane is mounted to the fuselage at the base of the fin. Advantages T-tails were common in early jet aircraft. Designers were worried that an engine failure would otherwise damage the horizontal tail. The T-tail is very common on aircraft with engines mounted in nacelles on a high-winged aircraft or on aircraft with the engines mounted on the rear of the fuselage, as it keeps the tail clear of the jet exhaust. Rear-mounting the engines keeps the wings clean and improves short-field performance. This was necessary in early jet aircraft with less powerful engines. T-tail aircraft can have better short-field performance, such as on the Avro RJ-85. The disturbed airflow over a lower stabilizer can make control more difficult at lower speeds. Dur ...

Shoulder Wing
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplane (aeronautics), multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External Bracing (aeronautics), bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, ...
