Tupolev Tu-28
The Tupolev Tu-28 ( NATO reporting name Fiddler) was a long-range interceptor aircraft introduced by the Soviet Union in the 1960s. The official designation was Tu-128, but this designation was less commonly used in the West. It was the largest and heaviest fighter ever in service. Background In the 1950s, the Soviet Union sought means to defend against nuclear-armed American bombers possibly penetrating its borders (especially its long and vulnerable northern border). Contemporary interceptors, such as the Yakovlev Yak-28P, were able to cover a radius of just a few hundred kilometers flying from northern Soviet bases like Talagi and Savatiya; the newly developed surface-to-air missiles had even shorter range. Considering both, the sheer numbers required to defend a 5,000 km air front were economically impossible to maintain. This left the Soviet Union able to provide a modern air defense only for selected valuable areas. The PVO decided to cover the entire territory, ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

Savatiya (air Base)
Savatiya (also Kotlas South, Savati, or Savvatiya) is an air base in Arkhangelsk Oblast, Russia located 29 km south of Kotlas. It is a small interceptor airfield. It was home to 445 IAP (445th Interceptor Aviation Regiment) between 1967 and 1993, which received Tupolev Tu-128 (Fiddler) aircraft in 1967, MiG-25 aircraft by the late 1970s, and MiG-31 by the 1990s. It is also listed as being home to 458 IAP (458th Interceptor Aviation Regiment) which flew MiG-31 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.

Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for takeoff or landing. For aircraft it is generally needed for both. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or floats needed to operate from snow/ice/water and skids for vertical operation on land. Faster aircraft have retractable undercarriages, which fold away during flight to reduce drag. Some unusual landing gear have been evaluated experimentally. These include: no landing gear (to save weight), made possible by operating from a catapult cradle and flexible landing deck: air cushion (to enable operation over a wide range of ground obstacles and wat ...

Swept Wing
A swept wing is a wing that angles either backward or occasionally forward from its root rather than in a straight sideways direction. Swept wings have been flown since the pioneer days of aviation. Wing sweep at high speeds was first investigated in Germany as early as 1935 by Albert Betz and Adolph Busemann, finding application just before the end of the Second World War. It has the effect of delaying the shock waves and accompanying aerodynamic drag rise caused by fluid compressibility near the speed of sound, improving performance. Swept wings are therefore almost always used on jet aircraft designed to fly at these speeds. The term "swept wing" is normally used to mean "swept back", but variants include forward sweep, variable sweep wings and oblique wings in which one side sweeps forward and the other back. The delta wing is also aerodynamically a form of swept wing. Reasons for sweep There are three main reasons for sweeping a wing: 1. to arrange the center of gravity ...

Lavochkin La-250
The Lavochkin La-250 "Anakonda" was a high-altitude interceptor aircraft prototype developed in the Soviet Union by the Lavochkin design bureau in the 1950s. Its nickname "Anaconda" was invented during the flight test and referred to both the elongated body shape as well as the relatively critical flight characteristics of the machine. Development By the mid-1950s, it became obvious that subsonic cannon-armed fighters such as the Yakovlev Yak-25 would be unable to intercept fast high-altitude targets like the upcoming generation of strategic jet bombers. Consequently, in 1953 Lavochkin OKB proposed addition of an air-to-air missile system to the ''Berkut'' air-defense system. Tasked with defense of Moscow, the ''Berkut'' system consisted of a large network of radars and surface-to-air missile sites as well as ground-controlled interceptor aircraft. Lavochkin's proposed missile, the G-300 utilized a guidance system based on vacuum tubes and was so heavy (about 1,000 kg (2, ...

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 ...

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 ...

Endurance (aircraft)
In aviation, endurance is the maximum length of time that an aircraft can spend in Cruise (aeronautics), cruising flight. In other words, it is the amount of time an aircraft can stay in the air with one load of fuel. Endurance is different from range (aeronautics), range, which is a measure of distance flown. For example, a typical sailplane exhibits high endurance characteristics but poor range characteristics. Endurance can be defined as: :E=\int_^dt=-\int_^\frac=\int_^\frac where W stands for fuel weight, F for fuel flow, and t for time. Endurance can factor into aviation design in a number of ways. Some aircraft, such as the P-3 Orion or Lockheed U-2, U-2 spy plane, require high endurance characteristics as part of their mission profile (often referred to as Loiter (aeronautics), loiter time (on target)). Endurance plays a prime factor in finding out the fuel fraction for an aircraft. Endurance, like range, is also related to fuel efficiency; fuel-efficient aircraft will te ...

Supersonic
Supersonic speed is the speed of an object that exceeds the speed of sound ( Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level, this speed is approximately . Speeds greater than five times the speed of sound (Mach 5) are often referred to as hypersonic. Flights during which only some parts of the air surrounding an object, such as the ends of rotor blades, reach supersonic speeds are called transonic. This occurs typically somewhere between Mach 0.8 and Mach 1.2. Sounds are traveling vibrations in the form of pressure waves in an elastic medium. Objects move at supersonic speed when the objects move faster than the speed at which sound propagates through the medium. In gases, sound travels longitudinally at different speeds, mostly depending on the molecular mass and temperature of the gas, and pressure has little effect. Since air temperature and composition varies significantly with altitude, the speed of s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anadyr (town)
Anadyr ( rus, Ана́дырь, a=Ru-Anadyr.ogg, r=Anadyr, p=ɐˈnadɨrʲ; Chukchi: , ''Kagyrgyn'', ; Southern Chukchi: Въэӈын, ''V"èňyn'') is a port town and the administrative center of Chukotka Autonomous Okrug, Russia, located at the mouth of the Anadyr River at the tip of a peninsula that protrudes into Anadyrsky Liman. Anadyr is the easternmost town in Russia; more easterly settlements, such as Provideniya and Uelen, do not have town status. It was previously known as ''Novo–Mariinsk'' (until 1923). Population: History Early history Although the town itself has only been in existence for just over a century, the origins of the name Anadyr are much older. The name initially derives from the Yukaghir word "''any-an''" meaning "''river''". When Semyon Dezhnev met Yukaghir people in the area, the indigenous name was corrupted to form "''Onandyr''", later Anadyrsk, the name of the '' ostrog'' (fort) upstream of the present-day settlement, from which the current ...
