AA-9 Amos
The R-33 (russian: Вымпел Р-33, NATO reporting name: AA-9 Amos) is a long-range air-to-air missile developed by Vympel NPO, Vympel. It is the primary armament of the Mikoyan MiG-31, MiG-31 interceptor, intended to attack large high-speed targets such as the SR-71 Blackbird, the B-1 Lancer bomber, and the B-52 Stratofortress. It uses a combination of semi-active radar homing for initial acquisition and mid-course updates, and inertial navigation to reach the target at extreme range. The Zaslon phased array radar of MiG-31 allows four missiles to be guided simultaneously at separate targets. The R-33 AAM remains in service with the Commonwealth of Independent States, CIS and Russian forces (See Mikoyan MiG-31#Operators, MiG-31 operators). Development The history of the R-33 missile is tightly bound to the story of its launcher, the MiG-31. The development of the modernized MiG-25, E-155MP, was authorized by a governmental decision of 24 May 1968. There was a competition for ...

MiG-31 Gear And R-33
The Mikoyan MiG-31 (russian: link=no, Микоян МиГ-31; NATO reporting name: Foxhound) is a supersonic interceptor aircraft that was developed for use by the Soviet Air Forces. The aircraft was designed by the Mikoyan design bureau as a replacement for the earlier MiG-25 "Foxbat"; the MiG-31 is based on and shares design elements with the MiG-25. The MiG-31 is among the fastest combat jets in the world. It continues to be operated by the Russian Air Force and the Kazakh Air Force following the end of the Cold War and the collapse of the Soviet Union in 1991. The Russian Defence Ministry expects the MiG-31 to remain in service until 2030 or beyond; that was confirmed in 2020 when an announcement was made to extend the service lifetime from 2,500 to 3,500 hours on the existing airframes. Development Origins The single-seat MiG-25 could achieve high speed, altitude and rate of climb; however, it lacked maneuverability at interception speeds and was difficult to fly at ...

MiG-25
The Mikoyan-Gurevich MiG-25 (russian: Микоян и Гуревич МиГ-25; NATO reporting name: Foxbat) is a supersonic interceptor and reconnaissance aircraft that is among the fastest military aircraft to enter service. Designed by the Soviet Union's Mikoyan-Gurevich bureau, it is an aircraft built primarily using stainless steel. It was to be the last plane designed by Mikhail Gurevich, before his retirement. The first prototype flew in 1964 and the aircraft entered service in 1970. It has an operational top speed of Mach 2.83. Although its thrust was sufficient to reach Mach 3.2+, its speed was limited to prevent engines from overheating at higher air speeds and possibly damaging them beyond repair."Intelligence: Big-Mouth Belenko" ''Time'', 11 Octob ...

Warhead
A warhead is the forward section of a device that contains the explosive agent or toxic (biological, chemical, or nuclear) material that is delivered by a missile, rocket, torpedo, or bomb. Classification Types of warheads include: * Explosive: An explosive charge is used to disintegrate the target, and damage surrounding areas with a blast wave. ** Conventional: Chemicals such as gunpowder and high explosives store significant energy within their molecular bonds. This energy can be released quickly by a trigger, such as an electric spark. Thermobaric weapons enhance the blast effect by utilizing the surrounding atmosphere in their explosive reactions. *** Blast: A strong shock wave is provided by the detonation of the explosive. *** Fragmentation: Metal fragments are projected at high velocity to cause damage or injury. *** Continuous rod: Metal bars welded on their ends form a compact cylinder of interconnected rods, which is violently expanded into a contiguous zig- ...

F-14
The Grumman F-14 Tomcat is an American carrier-capable supersonic, twin-engine, two-seat, twin-tail, variable-sweep wing fighter aircraft. The Tomcat was developed for the United States Navy's Naval Fighter Experimental (VFX) program after the collapse of the General Dynamics-Grumman F-111B project. The F-14 was the first of the American Teen Series fighters, which were designed incorporating air combat experience against MiG fighters during the Vietnam War. The F-14 first flew on 21 December 1970 and made its first deployment in 1974 with the U.S. Navy aboard , replacing the McDonnell Douglas F-4 Phantom II. The F-14 served as the U.S. Navy's primary maritime air superiority fighter, fleet defense interceptor, and tactical aerial reconnaissance platform into the 2000s. The Low Altitude Navigation and Targeting Infrared for Night ( LANTIRN) pod system was added in the 1990s and the Tomcat began performing precision ground-attack missions. The Tomcat was retired by U.S. Navy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AIM-54 Phoenix
The AIM-54 Phoenix is an American radar-guided, long-range air-to-air missile (AAM), carried in clusters of up to six missiles on the Grumman F-14 Tomcat, its only operational launch platform. The Phoenix was the United States' only long-range air-to-air missile. The combination of Phoenix missile and the Tomcat's AN/AWG-9 guidance radar meant that it was the first aerial weapons system that could simultaneously engage multiple targets. Due to its active radar tracking, the brevity code " Fox Three" was used when firing the AIM-54. Both the missile and the aircraft were used by Iran and the United States Navy. In US service both are now retired, the AIM-54 Phoenix in 2004 and the F-14 in 2006. They were replaced by the shorter-range AIM-120 AMRAAM, employed on the F/A-18 Hornet and F/A-18E/F Super Hornet—in its AIM-120D version, the latest version of the AMRAAM just matches the Phoenix's maximum range. The AIM-54 has been used in 62 air-to-air strikes, all by Iran during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inertial Guidance System
An inertial navigation system (INS) is a navigation device that uses motion sensors ( accelerometers), rotation sensors ( gyroscopes) and a computer to continuously calculate by dead reckoning the position, the orientation, and the velocity (direction and speed of movement) of a moving object without the need for external references. Often the inertial sensors are supplemented by a barometric altimeter and sometimes by magnetic sensors ( magnetometers) and/or speed measuring devices. INSs are used on mobile robots and on vehicles such as ships, aircraft, submarines, guided missiles, and spacecraft. Other terms used to refer to inertial navigation systems or closely related devices include inertial guidance system, inertial instrument, inertial measurement unit (IMU) and many other variations. Older INS systems generally used an inertial platform as their mounting point to the vehicle and the terms are sometimes considered synonymous. Overview Inertial navigation is ...

Model Aircraft
A model aircraft is a small unmanned aircraft. Many are replicas of real aircraft. Model aircraft are divided into two basic groups: flying and non-flying. Non-flying models are also termed static, display, or shelf models. Aircraft manufacturers and researchers make wind tunnel models for testing aerodynamic properties, for basic research, or for the development of new designs. Sometimes only part of the aircraft is modelled. Static models range from mass-produced toys in white metal or plastic to highly accurate and detailed models produced for museum display and requiring thousands of hours of work. Many are available in kits, typically made of injection-moulded polystyrene or resin. Flying models range from simple toy gliders made of sheets of paper, balsa, card stock or foam polystyrene to powered scale models built up from balsa, bamboo sticks, plastic, (including both moulded or sheet polystyrene, and styrofoam), metal, synthetic resin, either alone or with carbon fib ...

Radar
Radar is a detection system that uses radio waves to determine the distance ('' ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. Th ...

Tupolev Tu-104
The Tupolev Tu-104 (NATO reporting name: Camel) is a retired twinjet, medium-range, narrow-body turbojet-powered Soviet airliner. It was the second to enter regular service, behind the British de Havilland Comet, and was the only jetliner operating in the world from 1956 to 1958, when the British jetliner was grounded due to safety concerns. In 1957, Czechoslovak Airlines – ČSA, (now Czech Airlines) became the first airline in the world to fly a route exclusively with jet airliners, using the Tu-104A variant between Prague and Moscow. In civil service, the Tu-104 carried over 90 million passengers with Aeroflot (then the world's largest airline), and a lesser number with ČSA, while it also was operated by the Soviet Air Force. Its successors included the Tu-124, Tu-134, and Tu-154. Design and development At the beginning of the 1950s, the Soviet Union's Aeroflot airline needed a modern airliner with better capacity and performance than the piston-engined aircraft th ...

Guidance System
A guidance system is a virtual or physical device, or a group of devices implementing a controlling the movement of a ship, aircraft, missile, rocket, satellite, or any other moving object. Guidance is the process of calculating the changes in position, velocity, altitude, and/or rotation rates of a moving object required to follow a certain trajectory and/or altitude profile based on information about the object's state of motion. A guidance system is usually part of a Guidance, navigation and control system, whereas navigation refers to the systems necessary to calculate the current position and orientation based on sensor data like those from compasses, GPS receivers, Loran-C, star trackers, inertial measurement units, altimeters, etc. The output of the navigation system, the navigation solution, is an input for the guidance system, among others like the environmental conditions (wind, water, temperature, etc.) and the vehicle's characteristics (i.e. mass, control system ...

MiG-21
The Mikoyan-Gurevich MiG-21 (russian: Микоян и Гуревич МиГ-21; NATO reporting name: Fishbed) is a supersonic jet fighter and interceptor aircraft, designed by the Mikoyan-Gurevich Design Bureau in the Soviet Union. Its nicknames include: "balalaika", because its planform resembles the stringed musical instrument of the same name; "''Ołówek''", Polish for "pencil", due to the shape of its fuselage, and "''Én Bạc''", meaning "silver swallow", in Vietnamese. Approximately 60 countries across four continents have flown the MiG-21, and it still serves many nations six decades after its maiden flight. It set aviation records, becoming the most-produced supersonic jet aircraft in aviation history, the most-produced combat aircraft since the Korean War and, previously, the longest production run of any combat aircraft (now exceeded by both the McDonnell Douglas F-15 Eagle and General Dynamics F-16 Fighting Falcon).

Wing
A wing is a type of fin that produces lift while moving through air or some other fluid. Accordingly, wings have streamlined cross-sections that are subject to aerodynamic forces and act as airfoils. A wing's aerodynamic efficiency is expressed as its lift-to-drag ratio. The lift a wing generates at a given speed and angle of attack can be one to two orders of magnitude greater than the total drag on the wing. A high lift-to-drag ratio requires a significantly smaller thrust to propel the wings through the air at sufficient lift. Lifting structures used in water include various foils, such as hydrofoils. Hydrodynamics is the governing science, rather than aerodynamics. Applications of underwater foils occur in hydroplanes, sailboats and submarines. Etymology and usage For many centuries, the word "wing", from the Old Norse ''vængr'', referred mainly to the foremost limbs of birds (in addition to the architectural aisle). But in recent centuries the word's meanin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
