Bodyflight
Bodyflight, or body flight, is a term in skydiving which means staying or moving of a body or system of bodies in the air flow. It is one of the most dynamically developing sports in the world. In the windtunnel sport parachuting and skydiving, bodyflight is performed by applying air flow on certain parts of a body, to control the body any muscular forces can be used. As a tool for learning to control the body flight, there is a vertical wind tunnel, which makes it possible to fly in the air, simulating free fall due to the created air flow (on average, about 190 km/h). Bodyflight includes various flight poses, movements and flight transits, when combined, flight elements (tricks) are formed. Also this include turns, rolls, lateral movement, fall rate control, and other acrobatics in the air. The skill of bodyflight makes it possible for skydivers to fly closer to each other while they are falling, to allow them to link together in formation skydiving, then fly apart to a safe d ...

Skydiving
Parachuting and skydiving are methods of descending from a high point in an atmosphere to the ground or ocean surface with the aid of gravity, involving the control of speed during the descent using a parachute or multiple parachutes. For human skydiving, there is often a phase of free fall (the skydiving segment), where the parachute has not yet been deployed and the body gradually accelerates to terminal velocity. In cargo parachuting, the parachute descent may begin immediately, such as a parachute-airdrop in the Troposphere, lower atmosphere of Earth, or it may be significantly delayed. For example, in a planetary atmosphere, where an object is descending "under parachute" following atmospheric entry from outer space, space, may occur only after the hypersonic entry phase and initial deceleration that occurs due to aerodynamic drag, friction with the thin upper atmosphere. History The first parachute jump in history was made on 22 October 1797 by Frenchman André-Jacq ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Formation Skydiving
Formation skydiving is a skydiving event where multiple skydivers attach themselves to one another by grabbing each other's limbs or by the use of "grippers" on their jumpsuit while free falling through the sky. The goal of this skydiving program is to build a formation of multiple divers arranged in a geometric pattern. Sub-categories Formation skydiving can be further divided into several sub-categories, so named for the number of members in a team: *4-way sequential *4-way vertical sequential (VFS, Vertical Formation Skydiving) *8-way sequential *16-way sequential *10-way speed *Large formations (Big-ways) Competitive format A competition in 4-way formation skydiving (FS-4) takes place like this: There are two kinds of formations, called randoms and blocks. The randoms are singular formations with full separation of all grips both before and after building the formation. The blocks are double formations with a special designated movement pattern in between, called an int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Popular Mechanics
''Popular Mechanics'' (often abbreviated as ''PM'' or ''PopMech'') is a magazine of popular science and technology, featuring automotive, home, outdoor, electronics, science, do it yourself, and technology topics. Military topics, aviation and transportation of all types, space, tools and gadgets are commonly featured. It was founded in 1902 by Henry Haven Windsor, who was the editor and—as owner of the Popular Mechanics Company—the publisher. For decades, the tagline of the monthly magazine was "Written so you can understand it." In 1958, PM was purchased by the Hearst Corporation, now Hearst Communications. In 2013, the US edition changed from twelve to ten issues per year, and in 2014 the tagline was changed to "How your world works." The magazine added a podcast in recent years, including regular features ''Most Useful Podcast Ever'' and ''How Your World Works''. History ''Popular Mechanics'' was founded as a weekly in Chicago by Henry Haven Windsor, with the first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ski Jumping
Ski jumping is a winter sport in which competitors aim to achieve the farthest jump after sliding down on their skis from a specially designed curved ramp. Along with jump length, competitor's aerial style and other factors also affect the final score. Ski jumping was first contested in Norway in the late 19th century, and later spread through Europe and North America in the early 20th century. Along with cross-country skiing, it constitutes the traditional group of Nordic skiing disciplines. The ski jumping hill, ski jumping venue, commonly referred to as a ''hill'', consists of the jumping ramp (''in-run''), take-off table, and a landing hill. Each jump is evaluated according to the distance covered and the style performed. The distance score is related to the construction point (also known as the ''K-point''), which is a line drawn in the landing area and serves as a "target" for the competitors to reach. The score of each judge evaluating the style can reach a maximum of 20 p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airfoil
An airfoil (American English) or aerofoil (British English) is a streamlined body that is capable of generating significantly more Lift (force), lift than Drag (physics), drag. Wings, sails and propeller blades are examples of airfoils. Foil (fluid mechanics), Foils of similar function designed with water as the working fluid are called hydrofoils. When oriented at a suitable angle, a solid body moving through a fluid deflects the oncoming fluid (for fixed-wing aircraft, a downward force), resulting in a force on the airfoil in the direction opposite to the deflection. This force is known as aerodynamic force and can be resolved into two components: lift (perpendicular to the remote freestream velocity) and drag (Parallel (geometry), parallel to the freestream velocity). The lift on an airfoil is primarily the result of its angle of attack. Most foil shapes require a positive angle of attack to generate lift, but Camber (aerodynamics), cambered airfoils can generate lift at zero ...

Vice (magazine)
''Vice'' (stylized in all caps) is a Canadian-American magazine focused on lifestyle, arts, culture, and news/politics. It was founded in 1994 in Montreal as an alternative punk magazine, and its founders later launched the youth media company Vice Media, which consists of divisions including the printed magazine as well as a website, broadcast news unit, a film production company, a record label, and a publishing imprint. As of February 2015, the magazine's editor-in-chief is Ellis Jones. On 15 May 2023, Vice Media formally filed for Chapter 11 bankruptcy, as part of a possible sale to a consortium of lenders including Fortress Investment Group, which will, alongside Soros Fund Management and Monroe Capital, invest $225 million as a credit bid for nearly all of its assets. In February 2024, CEO Bruce Dixon announced additional layoffs and that the website Vice.com will no longer publish content. The print magazine returned in September 2024.
