Shenyang J-8II
The Shenyang J-8 (Chinese: 歼-8; NATO reporting name: Finback) is an interceptor aircraft developed by the 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 nose air intake and its shock cone with an ogival radome and lateral air intakes to create room for a modern fire-control radar, and used more powerful engines. The aircraft started development in 1982, and was cleared for production and service in 1988. The J-8II was the basis for ...

PL-2
The PL-2 () is an infrared homing (IRH) air-to-air missiles (AAM) developed in the People's Republic of China (PRC). It was a reverse-engineered Soviet Vympel K-13, which in turn was a reverse-engineered American AIM-9B Sidewinder. The PL-2 was the root of a family of AAMs; of the derivatives, only the PL-5B was successful. PL-2 The PRC acquired an intact AIM-9B during the Second Taiwan Strait Crisis in 1958. Air combat between over the strait between the Republic of China Air Force (ROCAF) and the People's Liberation Army Air Force (PLAAF) marked the combat debut of AAMs, with Sidewinder-armed ROCAF F-86 Sabres achieving notable success against PLAAF J-5s. On 28 September, a J-5 returned to base with an unexploded Sidewinder lodged in its airframe. The PRC's attempts to reverse engineer the AIM-9B failed. The PRC transferred the missile to the Soviet Union, which agreed to share the reverse engineered product; in 1961, the PRC received technical data for and examples of the K ...

Air-to-air Missile
The newest and the oldest member of Rafael's Python family of AAM for comparisons, Python-5 (displayed lower-front) and Shafrir-1 (upper-back) An air-to-air missile (AAM) is a missile fired from an aircraft for the purpose of destroying another aircraft. AAMs are typically powered by one or more rocket motors, usually solid fueled but sometimes liquid fueled. Ramjet engines, as used on the Meteor, are emerging as propulsion that will enable future medium-range missiles to maintain higher average speed across their engagement envelope. Air-to-air missiles are broadly put in two groups. Those designed to engage opposing aircraft at ranges of less than 16 km are known as short-range or "within visual range" missiles (SRAAMs or WVRAAMs) and are sometimes called " dogfight" missiles because they are designed to optimize their agility rather than range. Most use infrared guidance and are called heat-seeking missiles. In contrast, medium- or long-range missiles (MRAAMs or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PL-4 (missile)
The PL-4 () was an air-to-air missile (AAM) developed by the People's Republic of China. It was designed by the 612 Research Institute and the Zhuzhou Aeroengine factory. The first version, the PL-4A, was China's first semi-active radar homing (SARH) AAM. It was developed into the infrared homing PL-4B. The development program started in March 1966. The design may have been influenced by American AIM-7D Sparrow wreckage from the Vietnam War. Prototype ground-testing to the original 1960s requirements was completed in November 1980, with the second phase of development starting in July 1981.Wood et al. (2020): page 17 The program was cancelled in 1984 due to obsolescence and, with the normalization of relations with the United States - the availability of modern Western weapons.Wood et al. (2020): page 34 The PL-4 was intended to arm the Chengdu J-9 - which was cancelled in 1980 - and then the Shenyang J-8II The Shenyang J-8 (Chinese: 歼-8; NATO reporting name: Finback) is ...

Taxiing
Taxiing (rarely spelled taxying) is the movement of an aircraft on the ground, under its own power, in contrast to towing or pushback where the aircraft is moved by a tug. The aircraft usually moves on wheels, but the term also includes aircraft with skis or floats (for water-based travel). An airplane uses taxiways to taxi from one place on an airport to another; for example, when moving from a hangar to the runway. The term "taxiing" is not used for the accelerating run along a runway prior to takeoff, or the decelerating run immediately after landing, which are called the takeoff roll and landing rollout, respectively. Etymology As early as 1909 aviation journalists envisioned aeroplanes to replace the taxicab in traffic-congested cities. Some aviators and some linguists report that around the year 1911 the slang word "taxi" was in use for an "airplane". They suggest that the way aircraft move under power before they take off or after they land reminded someone ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aviation Accidents And Incidents
An aviation accident is defined by the Convention on International Civil Aviation Annex 13 as an occurrence associated with the operation of an aircraft, which takes place from the time any person boards the aircraft with the ''intention of flight'' until all such persons have disembarked, and in which a) a person is fatally or seriously injured, b) the aircraft sustains significant damage or structural failure, or c) the aircraft goes missing or becomes completely inaccessible. Annex 13 defines an aviation incident as an occurrence, other than an accident, associated with the operation of an aircraft that affects or could affect the safety of operation. A hull loss occurs if an aircraft is damaged beyond repair, lost, or becomes completely inaccessible. The first fatal aviation accident was the crash of a Rozière balloon near Wimereux, France, on June 15, 1785, killing the balloon's inventor, Jean-François Pilâtre de Rozier, and the other occupant, Pierre Romain.

Nudelman-Rikhter NR-30
The Nudelman-Rikhter NR-30 was a Soviet autocannon widely used in military aircraft of the Soviet Union and Warsaw Pact. It was designed by A.E. Nudelman and A. A. Rikhter, entering service in 1954. Description Prior to the introduction of the NR-30, most Soviet autocannon were of 23 or 37 mm calibre and often used in combination. For instance, the Mikoyan-Gurevich MiG-15 was equipped with two NR-23's and a single N-37. The two were mismatched; the NR-23 was a rapid-fire weapon with relatively low explosive power, while the N-37 was extremely powerful, typically able to destroy a bomber with a single hit, but with very a low firing rate which made it unsuited to firing at manoeuvring targets like fighters. Moreover, the two had very different ballistics which meant that long-range fire would result in one or the other set of guns being properly aimed. The NR-30 was an attempt to solve this problem by introducing a single weapon that could serve in both roles. It was es ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inlet Cone
Inlet cones (sometimes called shock cones or inlet centerbodies) are a component of some supersonic aircraft and missiles. They are primarily used on ramjets, such as the D-21 Tagboard and Lockheed X-7. Some turbojet aircraft including the Su-7, MiG-21, English Electric Lightning, and SR-71 also use an inlet cone. Purpose An inlet cone, as part of an Oswatitsch-type inlet used on a supersonic aircraft or missile, is the surface on which supersonic ram compression for a gas turbine engine or ramjet combustor takes place through oblique shock waves. Slowing the air to low supersonic speeds using a cone minimizes loss in total pressure (increases pressure recovery). Also, the cone, together with the inlet cowl lip, determine the area which regulates the flow entering the inlet. If the flow is more than that required by the engine then shock position instability(buzz) can occur. If less than that required then the pressure recovery is lower which reduces engine thrust. An inlet wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbojet
The turbojet is an airbreathing jet engine which is typically used in aircraft. It consists of a gas turbine with a propelling nozzle. The gas turbine has an air inlet which includes inlet guide vanes, a compressor, a combustion chamber, and a turbine (that drives the compressor). The compressed air from the compressor is heated by burning fuel in the combustion chamber and then allowed to expand through the turbine. The turbine exhaust is then expanded in the propelling nozzle where it is accelerated to high speed to provide thrust. Two engineers, Frank Whittle in the United Kingdom and Hans von Ohain in Germany, developed the concept independently into practical engines during the late 1930s. Turbojets have poor efficiency at low vehicle speeds, which limits their usefulness in vehicles other than aircraft. Turbojet engines have been used in isolated cases to power vehicles other than aircraft, typically for attempts on land speed records. Where vehicles are "turbine-pow ...
