Kulbit
The "Kulbit" (also known as the "Frolov chakra") is an aerial maneuver developed by Russian pilots in which the aircraft performs an extremely tight loop, often not much wider than the length of the aircraft itself. It differs from the traditional inside loop as it uses post-stall maneuvering capabilities, a type of supermaneuverability. Like most post-stall maneuvers, it demonstrates pitch control outside the normal flight envelope wherein pitch control is made possible by having aerodynamic flow over the aircraft's elevators or stabilators. The name "Kulbit" is derived from the Russian Кульбит, meaning "somersault". The alternate name, "Frolov's Chakra", refers to Russian test pilot Yevgeni Frolov, the pilot who first carried out the maneuver, while "chakra" is a yogic term, meaning "vortex" or "whirlpool". The Kulbit drastically decreases the aircraft's speed and could theoretically be used to cause a pursuing aircraft to overshoot its target. The maneuver is closely r ...

Su-37 Kulbit
The Sukhoi Su-37 (-37; NATO reporting name: Flanker-F; popularly nicknamed "Terminator") was a single-seat twin-engine aircraft designed by the Sukhoi Design Bureau which served as a technology demonstrator. It met the need to enhance pilot control of the Sukhoi Su-35, Su-27M (later renamed Su-35), a further development of the Su-27. The sole example built was originally the eleventh Su-27M (T10M-11) built by the Komsomolsk-on-Amur Aircraft Production Association before having thrust-vectoring nozzles installed. It also had 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, supermanoeuvrability at air shows, performing manoeuvres such as a Kulbit, 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 that Sukhoi had built a second Su-37 us ...

Pugachev's Cobra
In aerobatics, the cobra maneuver (or just the ''cobra''), also called ''dynamic deceleration'', among other names , is a dramatic and demanding maneuver in which an airplane flying at a moderate speed abruptly raises its nose momentarily to a vertical and slightly past vertical attitude, causing an extremely high angle of attack and making the plane into a full-body air brake, momentarily stalling the plane, before dropping back to normal position, during which the aircraft does not change effective altitude. The maneuver relies on the ability of the plane to be able to quickly change angle of attack (alpha) without overloading the airframe, and sufficient engine thrust to maintain nearly constant altitude through the entire move, but also post-stall stability and aerodynamics that allows for the recovery to level flight. The maneuver demands accurate pitch control, alpha stability and engine-versus-inlet compatibility for the aircraft, as well as a high skill level on the par ...

Inside Loop
Aerobatic maneuvers are flight paths putting aircraft in unusual attitudes, in air shows, dogfights or competition aerobatics. Aerobatics can be performed by a single aircraft or in formation with several others. Nearly all aircraft are capable of performing aerobatics maneuvers of some kind, although it may not be legal or safe to do so in certain aircraft. Aerobatics consist of five basic maneuvers: * Lines (both horizontal and vertical), * loops, * rolls, * spins, and * hammerheads. Most aerobatic figures are composites of these basic maneuvers with rolls superimposed. A loop is when the pilot pulls the plane up into the vertical, continues around until they are heading back in the same direction, like making a 360 degree turn, except it is in the vertical plane instead of the horizontal. The pilot will be inverted (upside down) at the top of the loop. A loop can also be performed by rolling inverted and making the same maneuver but diving towards the ground. It can be vi ...

Sukhoi Su-47 Berkut
The Sukhoi Su-47 ''Berkut'' () (NATO reporting name Firkin), also designated S-32 and S-37 during initial development, was a Russian experimental supersonic jet fighter developed by the JSC Sukhoi Company. A distinguishing feature of the aircraft was its forward-swept wingRussian Aviation Page: Sukhoi S-37 Berkut (S-32) which gave the aircraft excellent agility and maneuverability. While serial production of the type never materialized and the configuration was not further pursued, the sole aircraft produced served as a technology demonstrator prototype for a number of advanced technologies later used in the |
Sukhoi Su-35
The Sukhoi Su-35 (-35; NATO reporting name: Flanker-E/M, occasionally nicknamed "Super Flanker") is the designation for two improved derivatives of the Sukhoi Su-27, Su-27 air-defence fighter. They are single-seat, twinjet, twin-engine, supermaneuverability, supermaneuverable, 4.5 generation air superiority fighters, designed by the Sukhoi Design Bureau and built by Sukhoi. The type was originally developed by the Soviet Union from the Su-27 and was known as the Su-27M. It incorporated Canard (aeronautics), canards and a multi-function radar giving it multi-role capabilities. The first prototype made its maiden flight in June 1988. Following the dissolution of the Soviet Union Sukhoi re-designated it as the Su-35 to attract export orders. Fourteen aircraft were produced and used for tests and demonstrations; one example had Thrust vectoring, thrust-vectoring engines and was in turn redesignated the Sukhoi Su-37, Su-37. A sole Su-35UB two-seat trainer was also built in the late ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sukhoi Su-30
The Sukhoi Su-30 (; NATO reporting name: Flanker-C/G/H) is a twin-engine, two-seat supermaneuverable fighter aircraft developed in the Soviet Union in the 1980s by Russia's Sukhoi Aviation Corporation. It is a multirole fighter for all-weather, air-to-air interdiction missions. The Russian Aerospace Forces (VKS) were reported to have 130 Su-30SMs in operation as of 2024. The Su-30 started as an internal development project in the Sukhoi Su-27 family by Sukhoi. From the Su-27UB two-seat trainer, the Su-27PU heavy interceptor was developed. The design plan was revamped and the Su-27PU was renamed to Su-30 by the Russian Defense Ministry in 1996. Of the Flanker family, the Su-27, Su-30, Su-33, Su-34 and Su-35 have been ordered into limited or serial production by the Russian Defense Ministry. Later, different export requirements split the Su-30 into two distinct version branches, manufactured by competing organizations: KnAAPO and the Irkut Corporation, both of which come un ...

MiG-35
The Mikoyan MiG-35 (; NATO reporting name: Fulcrum-F) is a Russian multirole fighter that is designed by Mikoyan, a division of the United Aircraft Corporation (UAC). Marketed as a 4++ generation jet fighter, it is a further development of the MiG-29M/M2 and MiG-29K/KUB fighters. According to a Russian defense industry source, the Mikoyan MiG-35 is essentially an upgraded variant of the MiG-29KR. Many consider MiG-35 a new name given by Mikoyan for marketing. The first prototype was a modification of the aircraft that previously served as a MiG-29M2 model demonstrator given temporary name MiG-35 but a later prototype was a different model with different equipment that served as the base for the MiG-35 as is known today. Mikoyan first officially presented the MiG-35 internationally during the 2017 Moscow air show; the first two serial production aircraft entered service in 2019. The single-seat version is designated MiG-35S and the two-seat version MiG-35UB. The fighter has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

F-22 Raptor
The Lockheed Martin/Boeing F-22 Raptor is an American twin-engine, jet-powered, all-weather, supersonic stealth fighter aircraft. As a product of the United States Air Force's Advanced Tactical Fighter (ATF) program, the aircraft was designed as an air superiority fighter, but also incorporates ground attack, electronic warfare, and signals intelligence capabilities. The prime contractor, Lockheed Martin, built most of the F-22 airframe and weapons systems and conducted final assembly, while program partner Boeing provided the wings, aft fuselage, avionics integration, and training systems. First flown in 1997, the F-22 descended from the Lockheed YF-22 and was variously designated F-22 and F/A-22 before it formally entered service in December 2005 as the F-22A. Although the U.S. Air Force (USAF) had originally planned to buy a total of 750 ATFs to replace its F-15 Eagles, it later scaled down to 381, and the program was ultimately cut to 195 aircraft – 187 of the ...

Chakra
A chakra (; ; ) is one of the various focal points used in a variety of ancient meditation practices, collectively denominated as Tantra, part of the inner traditions of Hinduism and Buddhism. The concept of the chakra arose in Hinduism. Beliefs differ between the Indian religions: Buddhist texts mention four or five chakras, while Hindu sources often have six or seven. The modern "Western chakra system" arose from multiple sources, starting in the 1880s with H. P. Blavatsky and other Theosophists, followed by Sir John Woodroffe's 1919 book ''The Serpent Power'', and Charles W. Leadbeater's 1927 book ''The Chakras''. Psychological and other attributes, rainbow colours, and a wide range of correspondences with other systems such as alchemy, astrology, gemstones, homeopathy, Kabbalah and Tarot were added later. Etymology Lexically, ''chakra'' is the Indic reflex of an ancestral Indo-European languages, Indo-European form ''*kʷékʷlos'', whence also "wheel" and "cycl ...
