JF-17 Thunder
The CAC/PAC JF-17 Thunder (), or FC-1 ''Xiaolong'' (), is a fourth-generation, lightweight, single-engine, multirole combat aircraft developed jointly by the Pakistan Aeronautical Complex (PAC) and Chengdu Aircraft Corporation (CAC) of China. It was designed and developed as a replacement for the third-generation A-5C, F-7P/PG, Mirage III, and Mirage 5 combat aircraft in the Pakistan Air Force (PAF). The JF-17 can be used for multiple roles, including interception, ground attack, anti-ship, and aerial reconnaissance. The Pakistani designation "JF-17" stands for "Joint Fighter-17", with the "Joint Fighter" denoting the joint Pakistani-Chinese development of the aircraft and the "-17" denoting that, in the PAF's vision, it is the successor to the F-16. The Chinese designation "FC-1" stands for "Fighter China-1". The JF-17 can deploy diverse ordnance, including air-to-air, air-to-surface, and anti-ship missiles, guided and unguided bombs, and a 23 mm GSh-23-2 twin- ...

Pakistan Air Force
The Pakistan Air Force (PAF) (; ) is the aerial warfare branch of the Pakistan Armed Forces, tasked primarily with the aerial defence of Pakistan, with a secondary role of providing air support to the Pakistan Army and Pakistan Navy when required, and a tertiary role of providing strategic airlift capability to Pakistan. , per the International Institute for Strategic Studies, the PAF has more than 70,000 active-duty personnel. PAF is the largest Air Force of the Muslim world in terms of aircraft fleet. Its primary mandate and mission is "to provide, in synergy with other inter-services, the most efficient, assured and cost effective aerial defence of Pakistan." Since its establishment in 1947, the PAF has been involved in various combat operations, providing aerial support to the operations and relief efforts of the Pakistani military. Under Article 243, the Constitution of Pakistan appoints the president of Pakistan as the civilian commander-in-chief of the Pakistan Arme ...

Ground-attack Aircraft
An attack aircraft, strike aircraft, or attack bomber is a tactical military aircraft that has a primary role of carrying out airstrikes with greater precision than bombers, and is prepared to encounter strong low-level air defenses while pressing the attack.Mortensen 1987, pp. 24–25. This class of aircraft is designed mostly for close air support and naval air-to-surface missions, overlapping the tactical bomber mission. Designs dedicated to non-naval roles are often known as ground-attack aircraft.Gunston 2009, p. 73. Fighter aircraft often carry out the attack role, although they would not be considered attack aircraft ''per se''; fighter-bomber conversions of those same aircraft would be considered part of the class. Strike fighters, which have effectively replaced the fighter-bomber and light bomber concepts, also differ little from the broad concept of an attack aircraft. The dedicated attack aircraft as a separate class existed primarily during and after World War ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mach Number
The Mach number (M or Ma), often only Mach, (; ) is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity past a boundary to the local speed of sound. It is named after the Austrian physicist and philosopher Ernst Mach. \mathrm = \frac, where: * is the local Mach number, * is the local flow velocity with respect to the boundaries (either internal, such as an object immersed in the flow, or external, like a channel), and * is the speed of sound in the medium, which in air varies with the square root of the thermodynamic temperature. By definition, at Mach1, the local flow velocity is equal to the speed of sound. At Mach0.65, is 65% of the speed of sound (subsonic), and, at Mach1.35, is 35% faster than the speed of sound (supersonic). The local speed of sound, and hence the Mach number, depends on the temperature of the surrounding gas. The Mach number is primarily used to determine the approximation with which a flow can be treated as an i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbofan
A turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft engine, aircraft propulsion. The word "turbofan" is a combination of references to the preceding generation engine technology of the turbojet and the additional fan stage. It consists of a gas turbine engine which achieves mechanical energy from combustion, and a ducted fan that uses the mechanical energy from the gas turbine to force air rearwards. Thus, whereas all the air taken in by a turbojet passes through the combustion chamber and turbines, in a turbofan some of that air bypasses these components. A turbofan thus can be thought of as a turbojet being used to drive a ducted fan, with both of these contributing to the thrust. The ratio of the mass-flow of air bypassing the engine core to the mass-flow of air passing through the core is referred to as the bypass ratio. The engine produces thrust through a combination of these two portions working together. Engines that use more Propel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Klimov RD-93
The Klimov RD-33 is a turbofan jet engine for a lightweight fighter jet and which is the primary engine for the Mikoyan MiG-29 and CAC/PAC JF-17 Thunder. It was developed in OKB-117 led by S. P. Izotov (now OAO Klimov) from 1968 with production starting in 1981. Previous generations of Russian supersonic fighters such as the MiG-21 and MiG-23 used turbojets, but western fighters such as the F-111 and F-4K introduced the use of afterburning turbofans in the 1960s which were more efficient. The RD-33 was the first afterburning turbofan engine produced by the Klimov company of Russia in the thrust class. It features a modular twin-shaft design with individual parts that can be replaced separately. Variants In early 1970s the RD-33 was selected for new light fighter jet, later becoming Mikoyan MiG-29, the other option was Tumansky R-67-300. Years of development has built an extensive engine family. A newly designed thrust vectoring nozzle (TVN) is now available. New models of th ...

Guizhou WS-13
The WS-13 ( zh, 涡扇-13), codename Taishan, is a turbofan engine designed and manufactured by Guizhou Aircraft Industry Corporation to power the CAC/PAC JF-17 Thunder lightweight multirole fighter jointly developed by China and Pakistan, and in the near future the Shenyang FC-31 fifth-generation stealth fighter currently under development. Design and development China began development of the Taishan in 2000 to create a domestic engine for replacing the Klimov RD-93 turbofan, which had been selected in the 1990s to power the JF-17 lightweight fighter. It is designed to produce 86 kN (19,000 lb) of thrust with afterburner and have a life span of 2,200 hours; an improved version providing up to 93 kN (21,000 lb) of thrust with afterburner was also developed. The WS-13 Taishan was certified in 2007 and serial production began in 2009. The 18 March 2010 edition of the ''HKB Report'' stated that a JF-17 equipped with the WS-13 completed its first successf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autocannon
An autocannon, automatic cannon or machine cannon is a automatic firearm, fully automatic gun that is capable of rapid-firing large-caliber ( or more) armour-piercing, explosive or incendiary ammunition, incendiary shell (projectile), shells, as opposed to the smaller-caliber kinetic projectiles (bullets) fired by a machine gun. Autocannons have a longer effective range and greater terminal ballistics, terminal performance than machine guns, due to the use of larger/heavier munitions (most often in the range of , but bigger calibers also exist), but are usually smaller than tank guns, howitzers, field guns, or other artillery. When used on its own, the word "autocannon" typically indicates a non-rotary weapon with a single gun barrel, barrel. When multiple rotating barrels are involved, such a weapon is referred to as a "rotary autocannon" or "rotary cannon". If it uses a single barrel with a rotating cylinder with multiple chambers, it is known as a "revolver autocannon" or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gryazev-Shipunov GSh-23
The Gryazev-Shipunov GSh-23 () is a twin-barreled 23 mm autocannon developed in the Soviet Union, primarily for military aircraft use. It entered service in 1965, replacing the earlier Nudelman-Rikhter NR-23 and Rikhter R-23. The GSh-23 works on the Gast gun principle developed by German engineer Karl Gast of the Vorwerk company in 1916: it is a twin-barreled weapon in which the firing action of one barrel operates the mechanism of the other. The Gast principle provides a much faster rate of fire for lower mechanical wear than a single-barrel weapon. It cannot match the sustained rate of fire of an electrically operated multi-barrel rotary cannon such as the M61 Vulcan, but does not require an external power source, being powered by the recoil of the floating barrels, somewhat like the action of the German MG-42. The Gast principle has been little used in the West, but was used on a variety of weapons in the Soviet Union. The cannon comes in a basic GSh-23 variant, an ...

Anti-ship Missiles
An anti-ship missile (AShM or ASM) is a guided missile that is designed for use against ships and large boats. Most anti-ship missiles are of the sea-skimming variety, and many use a combination of inertial guidance and active radar homing. A large number of other anti-ship missiles use infrared homing to follow the heat that is emitted by a ship; it is also possible for anti-ship missiles to be guided by radio command all the way. Many anti-ship missiles can be launched from a variety of weapons systems including surface warships (also referred to as ship-to-ship missiles), submarines, bombers, fighter planes, patrol planes, helicopters, shore batteries, land vehicles, and, conceivably, even infantrymen firing shoulder-launched missiles. The term surface-to-surface missile (SSM) is used when appropriate. The longer-range anti-ship missiles are often called anti-ship cruise missiles. Several countries are also developing anti-ship ballistic missiles. Etymology Both ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air-to-surface Missile
An air-to-surface missile (ASM) or air-to-ground missile (AGM) is a missile designed to be launched from military aircraft at targets on land or sea. There are also unpowered guided glide bombs not considered missiles. The two most common propulsion systems for air-to-surface missiles are rocket motors, usually with shorter range, and slower, longer-range jet engines. Some Soviet Union, Soviet-designed air-to-surface missiles are powered by ramjets, giving them both long range and high speed. Missile guidance, Guidance for air-to-surface missiles is typically via laser guidance, infrared homing, infrared guidance, optical guidance or via satellite guidance signals. The type of guidance depends on the type of target. Ships, for example, may be detected via passive radar or active radar homing, which is less effective against multiple, small, fast-moving land targets. There is some cross-over between air-to-surface missiles and surface-to-surface missiles. For example, there was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air-to-air Missile
An air-to-air missile (AAM) is a missile fired from an aircraft for the purpose of destroying another aircraft (including unmanned aircraft such as cruise missiles). AAMs are typically powered by one or more rocket motors, usually solid-fuel rocket, solid fueled but sometimes liquid-fuel rocket, liquid fueled. Ramjet engines, as used on the Meteor (missile), Meteor, are emerging as propulsion that will enable future medium- to long-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 around 30 km to 40 km maximum 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 LRAAMs), which ...
