G-suit
A g-suit, or anti-''g'' suit, is a flight suit worn by aviators and astronauts who are subject to high levels of acceleration force ( g). It is designed to prevent a black-out and g-LOC (g-induced loss of consciousness) caused by the blood pooling in the lower part of the body when under acceleration, thus depriving the brain of blood. Black-out and g-LOC have caused a number of fatal aircraft accidents. Operation If blood is allowed to pool in the lower areas of the body, the brain will be deprived of blood. This lack of blood flow to the brain first causes a greyout (a dimming of the vision also called brownout), followed by tunnel vision and ultimately complete loss of vision 'blackout' followed by g-induced Loss Of Consciousness or 'g-LOC'. The danger of g-LOC to aircraft pilots is magnified because on relaxation of g-force there is a period of disorientation before full sensation is re-gained. A g-suit does not so much increase the g-threshold, but makes it possible to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flight Suit
A flight suit is a full-body garment, worn while flying aircraft such as military airplanes, Glider (aircraft), gliders and helicopters. These suits are generally made to keep the wearer warm, as well as being practical (plenty of pockets), and durable (including Fire-retardant material, fire retardant). Its appearance is usually similar to a jumpsuit. A military flight suit may also show Military rank, rank insignia. It is sometimes used by Special Forces as a combat uniform in close quarters battle or visit, board, search, and seizure situations, for its practicality. History As aviation developed in unheated open cockpits, the need for warm clothing quickly became apparent, as did the need for multiple pockets with closures of buttons, snaps, or zippers to prevent loss of articles during maneuvers. During Aviation in World War I, World War I, whilst motoring clothing was supplied, pilots were allowed to provide their own protective clothing by private purchase. Various typ ...

Fighter Aircraft
Fighter aircraft (early on also ''pursuit aircraft'') are military aircraft designed primarily for air-to-air combat. In military conflict, the role of fighter aircraft is to establish air supremacy, air superiority of the battlespace. Domination of the airspace above a battlefield permits bombers and attack aircraft to engage in tactical bombing, tactical and strategic bombing of enemy targets, and helps prevent the enemy from doing the same. The key performance features of a fighter include not only its firepower but also its high speed and maneuverability relative to the target aircraft. The success or failure of a combatant's efforts to gain air superiority hinges on several factors including the skill of its pilots, the tactical soundness of its doctrine for deploying its fighters, and the numbers and performance of those fighters. Many modern fighter aircraft also have secondary capabilities such as ground-attack aircraft, ground attack and some types, such as fighter-b ...

Banting And Best Department Of Medical Research
The University of Toronto (UToronto or U of T) is a public research university whose main campus is located on the grounds that surround Queen's Park in Toronto, Ontario, Canada. It was founded by royal charter in 1827 as King's College, the first institution of higher learning in Upper Canada. Originally controlled by the Church of England, the university assumed its present name in 1850 upon becoming a secular institution. It has three campuses: Mississauga, St. George, and Scarborough. Its main campus, St. George, is the oldest of the three and located in Downtown Toronto. U of T operates as a collegiate university, comprising 11 colleges, each with substantial autonomy on financial and institutional affairs and significant differences in character and history. The University of Toronto is the largest university in Canada with a total of 99,794 students across its three campuses. It offers over 700 undergraduate and 200 graduate programs.

G-LOC
g-force induced loss of consciousness (abbreviated as G-LOC, pronounced "JEE-lock") is a term generally used in aerospace physiology to describe a loss of consciousness occurring from excessive and sustained g-forces draining blood away from the brain causing cerebral hypoxia. The condition is most likely to affect pilots of high performance fighter and aerobatic aircraft or astronauts, but is possible on some extreme amusement park rides. G-LOC incidents have caused fatal accidents in high performance aircraft capable of sustaining high ''g'' for extended periods. High-g training for pilots of high performance aircraft or spacecraft often includes ground training for G-LOC in special centrifuges, with some profiles exposing pilots to 9 ''g''s for a sustained length of time. Effects of ''g''-forces Under increasing positive ''g''-force, blood in the body will tend to move from the head toward the feet. For higher intensity or longer duration, this can manifest progress ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frank Cotton
Frank Stanley Cotton (30 April 1890 – 23 August 1955) was an Australian lecturer in physiology, specialising in the study of the effects of physical strain on the human body. Early life Cotton was born on 30 April 1890 at Camperdown, Sydney, New South Wales. His father was the Australian politician Francis Cotton (1857–1942) who was a strong proponent of Georgism and played a key role in the rise of the Labour movement. He was the younger brother of Shackleton expeditioner and geology professor, Leo Arthur Cotton (1883–1963). Pioneer art photographer Olive Cotton was his niece.Nairn (2011) He attended Sydney Boys High School from 1904 to 1908. In 1917, Cotton married Catherine Drummond Smith, a geology demonstrator who taught at the University of Sydney. Inventions ;Anti-Gravity Suit In 1940, whilst at the University of Sydney, Professor Cotton invented the "Cotton aerodynamic anti-G flying suit" (G-suit), which prevented pilots from blacking out when making high sp ...

Dogfight
A dogfight, or dog fight, is an air combat manoeuvring, aerial battle between fighter aircraft that is conducted at close range. Modern terminology for air-to-air combat is air combat manoeuvring (ACM), which refers to tactical situations requiring the use of individual basic fighter maneuvers (BFM) to attack or evade one or more opponents. This differs from aerial warfare, which deals with the strategy involved in planning and executing various missions. Dogfighting first occurred during the Mexican Revolution in 1913, shortly after the invention of the airplane. It was a component of every major war after that, though with steadily declining frequency, until the end of the Cold War in the early 1990s. Since then, longer-range weapons such as beyond-visual-range missiles have made dogfighting largely obsolete. Etymology The term ''dogfight'' has been used for centuries to describe a melee: a fierce, fast-paced close quarters battle, battle at close quarters between two or mo ...

RAF High Speed Flight
The RAF High Speed Flight, sometimes known as '' 'The Flight' '', was a small flight of the Royal Air Force (RAF) formed for the purpose of competing in the Schneider Trophy contest for racing seaplanes during the 1920s. The flight was together only until the trophy was won outright, after which it was disbanded. Background In the Schneider Trophy race of 1926 both competing countries, Italy and the United States, had used military pilots. There had not been time to arrange a British team to compete. The British defeat of 1925 was held to be the result of technical inferiority and lack of organisation."Supermarine S.5: 1927 Schneider Trophy - Venice, Italy." ''Racing Campbells.''

Schneider Trophy
The Coupe d'Aviation Maritime Jacques Schneider, also known as the Schneider Trophy, Schneider Prize or (incorrectly) the Schneider Cup is a trophy that was awarded first annually, and later biennially, to the winner of a race for seaplanes and flying boats. In 1931 Britain met the conditions to retain the Trophy permanently; it is on display at the Science Museum in South Kensington, London. Announced in 1912 by Jacques Schneider, a French financier, balloonist and aircraft enthusiast, the competition offered a prize of approximately £1,000. The race was held twelve times between 1913 and 1931, the year when it was finally won permanently by the British. It was intended to encourage technical advances in civil aviation but became a contest for pure speed with laps over a (usually) triangular course, initially and later extended to . The contests were staged as time trials, with aircraft setting off individually at set intervals, usually 15 minutes apart. The contests were v ...
