Aerobatics
Aerobatics is the practice of flying maneuvers involving aircraft attitudes that are not used in conventional passenger-carrying flights. The term is a portmanteau of "aerial" and "acrobatics". Aerobatics are performed in aeroplanes and gliders for training, recreation, entertainment, and sport. Additionally, some helicopters, such as the MBB Bo 105, are capable of limited aerobatic manoeuvres. An example of a fully aerobatic helicopter, capable of performing loops and rolls, is the Westland Lynx. Most aerobatic manoeuvres involve rotation of the aircraft about its longitudinal (roll) axis or lateral (pitch) axis. Other maneuvers, such as a spin, displace the aircraft about its vertical (yaw) axis. Manoeuvres are often combined to form a complete aerobatic sequence for entertainment or competition. Aerobatic flying requires a broader set of piloting skills and exposes the aircraft to greater structural stress than for normal flight. In some countries, the pilot must wear a ...

Aerobatic Manoeuvre
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 v ...

Competition Aerobatics
Competition aerobatics is an air sport in which ground-based judges rate the skill of pilots performing aerobatic flying. It is practised in both piston-powered single-engine airplanes and also gliders. An aerobatic competition is sanctioned by a national aero club, its designee, or in the case of international competitions, by CIVA, the Commission Internationale de Voltige Aerienne, which is a constituent body of the Fédération Aéronautique Internationale (FAI). The sanctioning body establishes the rules that apply to the competition, including entry qualifications for all participants, operating procedures, and judging criteria. A pilot enters a competition in a ''category'' of his or her choice, which defines the level of difficulty of the aerobatic sequences to be flown. Within each category, a pilot flies one or more ''flight programs''. Each flight receives a total score from the judges; ranking each pilot's combined total scores for all flight programs within each ...

Extra 300
The Extra Flugzeugbau EA300 is a two-seat aerobatic monoplane capable of Unlimited category competition. It was designed in 1987 by Walter Extra, a German aerobatic pilot, and built by Extra Flugzeugbau. Design and development Design of the Extra 300 was based on the Extra 230, an early 1980s monoplane having a wing made of wood. The Extra 300 has a welded steel tube fuselage covered in aluminium and fabric. The midset wing has a carbon fiber composite spar and carbon composite skins.Lambert 1993, p. 100. A symmetrical airfoil, mounted with a zero angle of incidence, provides equal performance in both upright and inverted flight. The landing gear is fixed taildragger style with composite main legs and fiberglass wheel pants. The powerplant is a fuel-injected Lycoming AEIO-540 which produces 300 horsepower (224 kW). The first two-seat Extra 300 made its maiden flight on 6 May 1988, with German type certification following on 16 May 1990. The single-seat Extra 300S ...

Pitts Special
The Pitts Special (company designations S-1 and S-2) is a series of light aerobatic biplanes designed by Curtis Pitts. It has accumulated many competition wins since its first flight in 1944. The Pitts biplanes dominated world aerobatic competition in the 1960s and 1970s and, even today, remain potent competition aircraft in the lower categories.Montgomery and Foster 1992, p. 92."Plane and Pilot" 1977, p. 84. Design and development Curtis Pitts began the design of a single-seat aerobatic biplane in 1943–1944.Taylor 1980, p. 899. The design has been refined continuously since the prototype first flew in September 1944; however, the current Pitts S-2 still remains quite close to the original in concept and in design. Several of the aircraft that Curtis Pitts built had a picture of a skunk on them and were called "Stinkers". After she bought it, aerobatic performer Betty Skelton called the second aircraft that Curtis built, "Little Stinker". The prototype S-2, wh ...

Spin (flight)
In flight dynamics a spin is a special category of stall resulting in autorotation (uncommanded roll) about the aircraft's longitudinal axis and a shallow, rotating, downward path approximately centred on a vertical axis. Spins can be entered intentionally or unintentionally, from any flight attitude if the aircraft has sufficient yaw while at the stall point. In a normal spin, the wing on the inside of the turn stalls while the outside wing remains flying. It is possible for both wings to stall, but the angle of attack of each wing, and consequently its lift and drag, are different. Either situation causes the aircraft to autorotate toward the stalled wing due to its higher drag and loss of lift. Spins are characterized by high angle of attack, an airspeed below the stall on at least one wing and a shallow descent. Recovery and avoiding a crash may require a specific and counter-intuitive set of actions. A spin differs from a spiral dive, in which neither wing is stalled ...

Formation Flying
Formation flying is the flight of multiple objects in coordination. Introduction Formation flight in aviation originated in World War I when fighter aircraft were assigned to escort reconnaissance aircraft. It was found that pairs of aircraft were more combat effective than single aircraft, and therefore, military aircraft would always fly in formations of at least two. By World War II, pilots had discovered other strategic advantages to formation flight such as enhanced stability and optimal visibility. However, birds have been known to receive performance benefits from formation flight for over a century, through aerodynamic theory of Wieselsberger in 1914. Today, a multitude of studies have been performed on the performance benefits of aircraft flying in formation. Mechanism of drag reduction It is a common misunderstanding to relate the reduction of drag in organized flight to the reduction of drag in drafting. However, they are quite different mechanistically. The d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sukhoi Su-26
The Sukhoi Su-26 is a single-seater aerobatic aircraft from the former Soviet Union, powered by a single radial reciprocating engine. The Su-26 has mid-mounted straight wings and fixed landing gear, the main gear mounted on a solid titanium arc. The Su-26 made its first flight in June 1984, the original four having a two-bladed propeller. The production switched to the Su-26M, with refined tail surfaces and a German-made MTV-9 3-blade composite propeller. Further refinements were made, and the model won both the men's and women's team prizes at the 1986 World Aerobatics Championships. The modified Su-26M3 with the new M9F engine dominated the 2003 and 2005 Aerobatic World Championships as well as the 2004 European Championships. The Su-26 has fully metric instruments, except for the altimeter. Specifications (Su-26) In popular culture '' IL-2 Sturmovik: Cliffs of Dover'' is a combat flight simulation video game mainly set in the Battle of Britain in 1940. Nevertheless, w ...

Cessna 152
The Cessna 152 is an American two-seat, fixed- tricycle-gear, general aviation airplane, used primarily for flight training and personal use. It was based on the earlier Cessna 150 incorporating a number of minor design changes and a slightly more powerful engine with a longer time between overhaul. The Cessna 152 has been out of production for almost forty years, but many are still airworthy and are in regular use for flight training. Development First delivered in 1977 as the 1978 model year, the 152 was a modernization of the proven Cessna 150 design. The 152 was intended to compete with the new Beechcraft Skipper and Piper Tomahawk, both of which were introduced the same year. Additional design goals were to improve useful load through a gross weight increase to , decrease internal and external noise levels and run better on the then newly introduced 100LL fuel.. As with the 150, the great majority of 152s were built at the Cessna factory in Wichita, Kansas. A numbe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alpha 2000
The Alpha Aviation Alpha 2000 is a two-seat, all-metal training and general aviation aircraft, designed by Chris Heintz and built in Hamilton, New Zealand. It continues the successful French Apex Aircraft's Robin R2000 series acquired upon Apex's purchase of the Avions Robin company. History 1971–1994 The original Avions Robin HR200 was designed by Christophe Heintz, to supplement the earlier Avions Robin designs of Jean Délémontez who also designed the popular post war wooden Jodel. The HR 200 prototype first flew on 19 July 1971, and entered production in 1973. The R2000 Alpha name was applied to a new aircraft which shared the fuselage of the HR 200, but had all new wing and tail surfaces, to allow aerobatics. The prototype R2000 Alpha flew on 15 January 1976 and production followed in 1977 to 1983. The aircraft features side-by-side seating, an innovative control stick mechanism which reduces the risk of blockage and an unusually large payload for an aerobatic aircra ...

Armed Forces
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats. In broad usage, the terms ''armed forces'' and ''military'' are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply ''military''. A nation's military ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patty Wagstaff At KBJC
A patty or burger (in British English) is a flattened, usually round, serving of ground meat and/or legumes, grains, vegetables, or meat alternatives. Patties are found in multiple cuisines throughout the world. In British and American English, minced meat that is formed into a disc is called a burger, whether it is in a bread roll or not. The word “patty” is also used in American English but almost unknown in British English. The ingredients are compacted and shaped, usually cooked, and served in various ways. Some foods termed "patties" use ingredients inside a pastry crust that is then baked or fried. Some patties are breaded, then baked or fried. In London, since the late 1980s, the Jamaican patty, similar to the Cornish pastie, is a common food item. Etymology The term originated in the 17th century as an English alteration of the French word pâté. According to the OED, it is related to the word pasty, which is various ingredients encased in pastry. Termino ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colored Smoke
Colored smoke is a kind of smoke created by an aerosol of small particles of a suitable pigment or dye. Colored smoke can be used for smoke signals, often in a military context. It can be produced by smoke grenades, or by various other pyrotechnical devices. The mixture used for producing colored smoke is usually a cooler-burning formula based on potassium chlorate oxidizer, lactose or dextrin as a fuel, and one or more dyes, with about 40-50% content of the dye. About 2% sodium bicarbonate may be added as a coolant, to lower the burning temperature. Coloured smoke was first used in 1967 during an American burnout competition by a small contestant, as a means to wow the crowd. Smoke released from aircraft was originally based on a mixture of 10-15% dye, 60-65% trichloroethylene or tetrachloroethylene, and 25% diesel oil, injected into the exhaust gases of the aircraft engines. Most commonly, teams now use specifically prepared liquid dyes and only gas oil, light mineral oil or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
