Sukhoi Su-37
The Sukhoi Su-37 (russian: link=no, Сухой Су-37; NATO reporting name: Flanker-F; popularly nicknamed "Terminator") was a single-seat twin-engine aircraft designed by the Sukhoi Design Bureau that served as a technology demonstrator. It allowed for the need to enhance pilot control of the Su-27M (later renamed Su-35), which was a further development of the Su-27. The sole aircraft had originally been built as the eleventh Su-27M (T10M-11) by the Komsomolsk-on-Amur Aircraft Production Association before having its thrust-vectoring nozzles installed. In addition, it was modified with updated flight- and weapons-control systems. The aircraft made its maiden flight in April 1996. Throughout the flight-test program, the Su-37 demonstrated its supermaneuverability at air shows, performing manoeuvres such as a 360-degree somersault. The aircraft crashed in December 2002 due to structural failure. The Su-37 did not enter production; despite a report in 1998 which claimed ...

Air Show
An air show (or airshow, air fair, air tattoo) is a public event where aircraft are exhibited. They often include aerobatics demonstrations, without they are called "static air shows" with aircraft parked on the ground. The largest air show measured by number of exhibitors and size of exhibit space is Le Bourget followed by Farnborough, while Dubai air show and Singapore Air Show are both claiming the third place. The largest air show or fly-in by number of participating airplanes is EAA AirVenture Oshkosh, commonly known as "Oshkosh" after its location in Wisconsin, with approximately 10,000 airplanes participating each year. The biggest military airshow in the world is the Royal International Air Tattoo, at RAF Fairford in England. Outline Some airshows are held as a business venture or as a trade event where aircraft, avionics and other services are promoted to potential customers. Many air shows are held in support of local, national or military charities. Milita ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vertical Stabilizer
A vertical stabilizer or tail fin is the static part of the vertical tail of an aircraft. The term is commonly applied to the assembly of both this fixed surface and one or more movable rudders hinged to it. Their role is to provide control, stability and trim in yaw (also known as directional or weathercock stability). It is part of the aircraft empennage, specifically of its stabilizers. The vertical tail is typically mounted on top of the rear fuselage, with the horizontal stabilizers mounted on the side of the fuselage (a configuration termed "conventional tail"). Other configurations, such as T-tail or twin tail, are sometimes used instead. Vertical stabilizers have occasionally been used in motor sports, with for example in Le Mans Prototype racing. Function Principle The vertical tail of an aircraft typically consists of a fixed vertical stabilizer or fin on which a movable rudder is mounted. A trim tab may similarly be mounted on the rudder. Together, their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glass Cockpit
A glass cockpit is an aircraft cockpit that features electronic (digital) flight instrument displays, typically large LCD screens, rather than the traditional style of analog dials and gauges. While a traditional cockpit relies on numerous mechanical gauges (nicknamed "steam gauges") to display information, a glass cockpit uses several multi-function displays driven by flight management systems, that can be adjusted to display flight information as needed. This simplifies aircraft operation and navigation and allows pilots to focus only on the most pertinent information. They are also popular with airline companies as they usually eliminate the need for a flight engineer, saving costs. In recent years the technology has also become widely available in small aircraft. As aircraft displays have modernized, the sensors that feed them have modernized as well. Traditional gyroscopic flight instruments have been replaced by electronic attitude and heading reference systems ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supermaneuverability
Supermaneuverability is the capability of fighter aircraft to execute tactical maneuvers that are not possible with purely aerodynamic techniques. Such maneuvers can involve controlled side-slipping or angles of attack beyond maximum lift. This capability was researched beginning in 1975 at the Langley Research Center in the United States, and eventually resulted in the development of the McDonnell Douglas F-15 STOL/MTD as a proof of concept aircraft. The Saab 35 Draken was another early aircraft with limited supermaneuverable capabilities. In 1983, the MiG-29 and in 1986, the Sukhoi Su-27 were deployed with this capability, which has since become standard in all of Russia's fourth- and fifth-generation aircraft. There has been some speculation, but the mechanism behind the supermaneuverability of the Russian-built aircraft has not been publicly disclosed. However, post-stall analyses have been increasingly used in recent years to advance maneuverability via the use of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbofan
The turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft propulsion. The word "turbofan" is a portmanteau of "turbine" and "fan": the ''turbo'' portion refers to a gas turbine engine which achieves mechanical energy from combustion, and the ''fan'', 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 jet thrust relative to fan thrust are known as ''low-bypass turbofans' ...

Armament
A weapon, arm or armament is any implement or device that can be used to deter, threaten, inflict physical damage, harm, or kill. Weapons are used to increase the efficacy and efficiency of activities such as hunting, crime, law enforcement, self-defense, warfare, or suicide. In broader context, weapons may be construed to include anything used to gain a tactical, strategic, material or mental advantage over an adversary or enemy target. While ordinary objects – sticks, rocks, bottles, chairs, vehicles – can be used as weapons, many objects are expressly designed for the purpose; these range from simple implements such as clubs, axes and swords, to complicated modern firearms, tanks, intercontinental ballistic missiles, biological weapons, and cyberweapons. Something that has been re-purposed, converted, or enhanced to become a weapon of war is termed weaponized, such as a weaponized virus or weaponized laser. History The use of weapons is a major driver of cult ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UEC Saturn
UEC NPO Saturn, PJSC (russian: ОДК-Сатурн НПО) is a Russian aircraft engine manufacturer, formed from the mergers of Rybinsk Motors and Lyul'ka-Saturn (after Arkhip Mikhailovich Lyulka) in 2001.

Axisymmetric
Rotational symmetry, also known as radial symmetry in geometry, is the property a shape has when it looks the same after some rotation by a partial turn. An object's degree of rotational symmetry is the number of distinct orientations in which it looks exactly the same for each rotation. Certain geometric objects are partially symmetrical when rotated at certain angles such as squares rotated 90°, however the only geometric objects that are fully rotationally symmetric at any angle are spheres, circles and other spheroids. Formal treatment Formally the rotational symmetry is symmetry with respect to some or all rotations in ''m''-dimensional Euclidean space. Rotations are direct isometries, i.e., isometries preserving orientation. Therefore, a symmetry group of rotational symmetry is a subgroup of ''E''+(''m'') (see Euclidean group). Symmetry with respect to all rotations about all points implies translational symmetry with respect to all translations, so space is homo ...
