Tailspin
In flight dynamics (fixed-wing aircraft), flight dynamics a spin is a special category of Stall (fluid dynamics), stall resulting in Autorotation (fixed-wing aircraft), 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 axis, 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 (force), lift and Drag (physics), 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 cr ...

Lincoln Beachey
Lincoln Beachey (March 3, 1887 – March 14, 1915) was a Aviation in the pioneer era, pioneer American aviator and barnstorming, barnstormer. He became famous and wealthy from flying exhibitions, staging aerial stunts, helping invent aerobatics, and setting aviation records. He was known as ''The Man Who Owns the Sky,'' and sometimes the ''Master Birdman''. Beachey was acknowledged even by his competitors as "The World's Greatest Aviator". He was "known by sight to hundreds of thousands and by name to the whole world". Career On 3 March 1887, Lincoln Beachey was born in San Francisco, and in 1903, first rode in a tethered balloon. In 1905, Lincoln and his older brother Hillery signed a contract with Thomas Scott Baldwin to fly his dirigible at the Lewis and Clark Centennial Exposition. On 10 September 1906, the Beachey brothers flew their dirigible around Washington, D.C., with Lincoln landing on the White House lawn, and then on the United States Capitol steps. Lincoln then ...

Angle Of Attack
In fluid dynamics, angle of attack (AOA, α, or \alpha) is the angle between a Airfoil#Airfoil terminology, reference line on a body (often the chord (aircraft), chord line of an airfoil) and the vector (geometry), vector representing the relative motion between the body and the fluid through which it is moving. Angle of attack is the angle between the body's reference line and the oncoming flow. This article focuses on the most common application, the angle of attack of a wing or airfoil moving through air. In aerodynamics, angle of attack specifies the angle between the chord line of the wing of a fixed-wing aircraft and the vector representing the relative motion between the aircraft and the atmosphere. Since a wing can have twist, a chord line of the whole wing may not be definable, so an alternate reference line is simply defined. Often, the chord line of the Wing root, root of the wing is chosen as the reference line. Another choice is to use a horizontal line on the fuse ...

Harry Bruno
Harry Augustine Bruno (7 February 1893 – 21 March 1978) was a promoter of aviation and boating, and a pioneer public relations professional. Biography Harry Bruno was born 7 February 1893 in London, England. His father Henry Augustine Bruno was a marine insurance analyst; his mother was Annie (Thompson) Bruno. In 1907 Henry brought his family to New York City. Young Harry came under the influence of Elbert Hubbard, who said simply, "To have a friend you must be a friend". Hubbard and Harry's parents were sailing on the RMS ''Lusitania'' when it sank on 7 May 1915. Both Hubbard and the Brunos died. Harry was very close to his brother Frank Bruno (1901–33) who worked in the newspaper business. In 1972 he married Evelyn Denny Witten, who was with him when he died 21 March 1978 in Southampton (town), New York, on Long Island. In 1910 Harry built a glider with his friend Bernie Mahon. Harry made a flight of 265 yards with it on 24 December. Harry and Bernie worked as runne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avro Type G
The Avro Type G was a two-seat biplane designed by A.V. Roe to participate in the 1912 British Military Aeroplane Competition. It is notable for having a fully enclosed crew compartment and for being the first aircraft to have recovered from a spin in front of witnesses. Design and development The Avro Type G was a two-seat, two-bay biplane with a fully enclosed crew compartment. The fuselage spanned the entire gap between the upper and lower wings, which featured Roe's characteristic high aspect ratio. Two prototypes were initiated, one equipped with a Green Green is the color between cyan and yellow on the visible spectrum.

Federal Aviation Regulations
The Federal Aviation Regulations (FARs) are rules prescribed by the Federal Aviation Administration (FAA) governing all aviation activities in the United States. The FARs comprise Title 14 of the Code of Federal Regulations (14 CFR). A wide variety of activities are regulated, such as aircraft design and maintenance, typical airline flights, pilot training activities, hot-air ballooning, lighter-than-air aircraft, human-made structure heights, obstruction lighting and marking, model rocket launches, commercial space operations, model aircraft operations, unmanned aircraft systems (UAS) and kite flying. The rules are designed to promote safe aviation, protecting pilots, flight attendants, passengers and the general public from unnecessary risk. FAR vs. 14 CFR Since 1958, these rules have typically been referred to as "FARs", short for Federal Aviation Regulations. However, another set of regulations (Title 48) is titled "Federal Acquisition Regulations", and this has led ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Utility Aircraft
A utility aircraft is a general-purpose light airplane or helicopter, usually used for transporting people, freight, or other supplies, but also used for other duties when more specialized aircraft are not required or available. The term can also refer to an aircraft type certificated under American, Canadian, European, or Australian regulations as a ''Utility Category Aircraft'', which indicates that it is permitted to conduct limited aerobatics. The approved maneuvers include chandelles, lazy eights, spins The spins (as in having "the spins") is an adverse reaction of Substance intoxication, intoxication that causes a state of vertigo and nausea, causing one to feel as if "spinning out of control", especially when lying down.

Chord (aeronautics)
In aeronautics, the chord is an imaginary straight line segment joining the leading edge and trailing edge of an aerofoil cross section parallel to the direction of the airflow. The chord length is the distance between the trailing edge and the leading edge. L. J. Clancy (1975), ''Aerodynamics'', Section 5.2, Pitman Publishing Limited, London. The point on the leading edge used to define the main chord may be the surface point of minimum radius. p.18 For a turbine aerofoil, the chord may be defined by the line between points where the front and rear of a 2-dimensional blade section would touch a flat surface when laid convex-side up. The wing, horizontal stabilizer, vertical stabilizer and propeller/rotor blades of an aircraft are all based on aerofoil sections, and the term ''chord'' or ''chord length'' is also used to describe their width. The chord of a wing, stabilizer and propeller is determined by measuring the distance between leading and trailing edges in the direc ...

Corkscrew
A corkscrew is a tool for drawing Cork (plug), corks from wine bottles and other household bottles that may be sealed with corks. In its traditional form, a corkscrew simply consists of a pointed metallic helix (often called the "worm") attached to a handle, which the user screws into the cork and pulls to extract it. Corkscrews are necessary because corks themselves, being small and smooth, are difficult to grip and remove, particularly when inserted fully into an inflexible glass bottle. More recent styles of corkscrew incorporate various systems of levers that further increase the amount of force that can be applied outwards upon the cork, making the extraction of difficult corks easier. History The design of the corkscrew may have been derived from the gun worm, which was a device from at least the early 1630s used by men to remove unspent charges from a musket's barrel in a similar fashion.winepros.com.au. The corkscrew is possibly an English invention, due to the tradit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boundary Layer
In physics and fluid mechanics, a boundary layer is the thin layer of fluid in the immediate vicinity of a Boundary (thermodynamic), bounding surface formed by the fluid flowing along the surface. The fluid's interaction with the wall induces a No-slip condition, no-slip boundary condition (zero velocity at the wall). The flow velocity then monotonically increases above the surface until it returns to the bulk flow velocity. The thin layer consisting of fluid whose velocity has not yet returned to the bulk flow velocity is called the velocity boundary layer. The air next to a human is heated, resulting in gravity-induced convective airflow, which results in both a velocity and thermal boundary layer. A breeze disrupts the boundary layer, and hair and clothing protect it, making the human feel cooler or warmer. On an aircraft wing, the velocity boundary layer is the part of the flow close to the wing, where viscosity, viscous forces distort the surrounding non-viscous flow. In ...
