List Of Chengdu J-7 Variants
The following is a list of variants and specifications for variants of the Chengdu J-7, which differed considerably between models in its 48 years of its production run. Production of the J-7 ceased after delivering of 16 F-7BGIs to the Bangladesh Air Force in 2013. Development Production of the J-7 lasted nearly half a century, beginning in November 1964 when Shenyang Aircraft Factory (SAC) started components manufacturing for aircraft, and eventually ended in May 2013. State certification of the first J-7 for series production was received on December 28, 1966, after Cultural Revolution started. As a result of the political turmoil caused, early production J-7s suffered quality issues that lasted into the 1980s, well after the end of the Cultural Revolution. More than 2,400 have been built in the many different models listed below. Type 1962/62 series Due to the Sino-Soviet split, Soviet-built MiG-21s were not used in China, and the few that were imported beforehand were referre ...

Chengdu J-7
The Chengdu J-7 (Chinese: 歼-7; third generation export version F-7; NATO reporting name: Fishcan) is a People's Republic of China fighter aircraft. It is a license-built version of the Soviet Mikoyan-Gurevich MiG-21, and thus shares many similarities with the MiG-21. The aircraft is armed with short-range, infrared homing air-to-air missiles and 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 ...

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 L ...

PL-8 (missile)
The PL-8 () is a Chinese air-to-air missile (AAM) originated from the Israeli Python-3 AAM. Experience gained from PL-8/Python-3 had helped China greatly in developing its next missile, the PL-9. Development and history The performance of Israeli Python-3 anti-air missile in the Lebanon conflict was observed by the Chinese military, People's Liberation Army Air Force (PLAAF) was reportedly impressed with this missile, and paid for licensed production as the PL-8 AAM in the 1980s, with the plan to producing the Python-3 with 100% local components approved by the PLAAF in 1982. The technology transfer accelerated Chinese missile development in the late Cold War. The program was code-named "Number 8 Project" (八号工程) and formally started on September 15, 1983. The missile entered service in 1986. The domestic manufacturer of the missile was Xi'an Eastern Machinery Factory (西安东方机械厂) located in Xi'an. From March 1988 to April 1989, technology transfer to China ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Head-up Display
A head-up display, or heads-up display, also known as a HUD (), is any transparent display that presents data without requiring users to look away from their usual viewpoints. The origin of the name stems from a pilot being able to view information with the head positioned "up" and looking forward, instead of angled down looking at lower instruments. A HUD also has the advantage that the pilot's eyes do not need to refocus to view the outside after looking at the optically nearer instruments. Although they were initially developed for military aviation, HUDs are now used in commercial aircraft, automobiles, and other (mostly professional) applications. Head-up displays were a precursor technology to augmented reality (AR), incorporating a subset of the features needed for the full AR experience, but lacking the necessary registration and tracking between the virtual content and the user's real-world environment. Overview A typical HUD contains three primary components: a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USAF
The United States Air Force (USAF) is the air service branch of the United States Armed Forces, and is one of the eight uniformed services of the United States. Originally created on 1 August 1907, as a part of the United States Army Signal Corps, the USAF was established as a separate branch of the United States Armed Forces in 1947 with the enactment of the National Security Act of 1947. It is the second youngest branch of the United States Armed Forces and the fourth in order of precedence. The United States Air Force articulates its core missions as air supremacy, global integrated intelligence, surveillance and reconnaissance, rapid global mobility, global strike, and command and control. The United States Air Force is a military service branch organized within the Department of the Air Force, one of the three military departments of the Department of Defense. The Air Force through the Department of the Air Force is headed by the civilian Secretary of the Air For ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PLANAF
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 ...

Afterburner
An afterburner (or reheat in British English) is an additional combustion component used on some jet engines, mostly those on military supersonic aircraft. Its purpose is to increase thrust, usually for supersonic flight, takeoff, and combat. The afterburning process injects additional fuel into a combustor in the jet pipe behind (''i.e.'', "after") the turbine, "reheating" the exhaust gas. Afterburning significantly increases thrust as an alternative to using a bigger engine with its attendant weight penalty, but at the cost of increased fuel consumption (decreased fuel efficiency) which limits its use to short periods. This aircraft application of "reheat" contrasts with the meaning and implementation of "reheat" applicable to gas turbines driving electrical generators and which reduces fuel consumption. Jet engines are referred to as operating ''wet'' when afterburning and ''dry'' when not. An engine producing maximum thrust wet is at ''maximum power,'' while an engine ...

Egyptian Air Force
The Egyptian Air Force (EAF) ( ar, القوات الجوية المصرية, El Qūwāt El Gawīyä El Maṣrīya), is the aviation branch of the Egyptian Armed Forces that is responsible for all airborne defence missions and operates all military aircraft, including those used in support of the Egyptian Army, Egyptian Navy and the Egyptian Air Defense Forces. The latter was created as a separate command in the 1970s and it coordinates with the Air Force to integrate air and ground-based air defense operations. The EAF is headed by an air marshal (lieutenant general equivalent). Currently, the commander of the Egyptian Air Force is Air Marshal Mohamed Abbas Helmy. The force's motto is 'Higher and higher for the sake of glory' ( ar, إلى العلا في سبيل المجد, '). It was known as the Royal Egyptian Air Force until 18 June 1953 following the declaration of the Republic of Egypt by Muhammad Naguib. The Egyptian Army Air Service was formed in 1932, and became an i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flight Instruments
Flight instruments are the instruments in the cockpit of an aircraft that provide the pilot with data about the flight situation of that aircraft, such as altitude, airspeed, vertical speed, heading and much more other crucial information in flight. They improve safety by allowing the pilot to fly the aircraft in level flight, and make turns, without a reference outside the aircraft such as the horizon. Visual flight rules (VFR) require an airspeed indicator, an altimeter, and a compass or other suitable magnetic direction indicator. Instrument flight rules (IFR) additionally require a gyroscopic pitch-bank (artificial horizon), direction (directional gyro) and rate of turn indicator, plus a slip-skid indicator, adjustable altimeter, and a clock. Flight into instrument meteorological conditions (IMC) require radio navigation instruments for precise takeoffs and landings. The term is sometimes used loosely as a synonym for cockpit instruments as a whole, in which context it can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Identification Friend Or Foe
Identification, friend or foe (IFF) is an identification system designed for command and control. It uses a transponder that listens for an ''interrogation'' signal and then sends a ''response'' that identifies the broadcaster. IFF systems usually use radar frequencies, but other electromagnetic frequencies, radio or infrared, may be used. It enables military and civilian air traffic control interrogation systems to identify aircraft, vehicles or forces as friendly and to determine their bearing and range from the interrogator. IFF is used by both military and civilian aircraft. IFF was first developed during World War II, with the arrival of radar, and several friendly fire incidents. IFF can only positively identify friendly aircraft or other forces. If an IFF interrogation receives no reply or an invalid reply, the object is not positively identified as foe; friendly forces may not properly reply to IFF for various reasons such as equipment malfunction, and parties in the area ...
