Hydroflight Sports
Hydroflight sports are a category of sport in which water jet propulsion is used to create sustained flight where lift and movement are controlled by a person riding on a propulsion device. Competitions for this sport started around 2012. There are many training centres throughout the world where beginners go to learn and practice skills so they can fly these devices by themselves. Types of hydroflight equipment There are many different types of Hydroflight products that are used for flying. The three most common types are the Jetboards, Jetpacks and Jetbikes, but there are others such as the Hoverboard and Freedom Flyer. Different varieties of jetboards are manufactured by different companies such as Jetblade, Flyboard, Defy X and Wataboard. This gives buyers a choice on which style board will suite their style of use. Jetboard The jetboard is a device that has two jets either side of the deck, on top of the deck is where the boots/bindings (generally wakeboarding boots) are bolte ...

Personal Watercraft
A personal watercraft (PWC), also called Jet Ski or water scooter, is a primarily recreational watercraft that is designed to hold only a small number of occupants, who sit or stand on top of the craft, not within the craft as in a boat. Prominent brands of PWCs include Jet Skis and Sea-Doos. PWCs have two style categories. The first and the most popular is a compact runabout (boat), runabout, typically holding no more than two or three people, who mainly sit on top of the watercraft as one does when riding an All-terrain vehicle, ATV or snowmobile. The second style is a "stand-up" type, typically built for only one occupant who operates the watercraft standing up as in riding a motorized scooter; it is used more for doing tricks, racing, and in competitions. Both styles have an inboard engine driving a pump-jet that has a screw-shaped impeller to create thrust for propulsion and steering. Most are designed for two or three people, though four-passenger models exist. Many o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Sports
The term "air sports" covers a range of aerial activities, including air racing, aerobatics, aeromodelling, hang gliding, human-powered aircraft, parachuting, paragliding, soaring, and skydiving. Recognized and regulated air sports Many air sports are regulated internationally by the Switzerland-based Fédération Aéronautique Internationale (FAI) and nationally by aero clubs such as the National Aeronautics Association (NAA) and the Royal Aero Club (RAeC). The FAI has separate commissions for each air sport. For example, the commission for ballooning is the Commission Internationale de l'Aérostation (CIA) and Federation of International Dronesoccer Association (FIDA). Sports within the categories of air sports and their respective commissions are as follows: Motorized * Aerobatics (CIVA) * Aeromodelling (CIAM) * Air racing (GAC) * Drone racing (CIAM) * Dronesoccer (FIDA) * Flyboarding * Powered hang gliding (CIMA) * Powered paragliding (CIMA) * Rally flying (GA ...

Water Sports
Water is an inorganic compound with the chemical formula . It is a transparent, tasteless, odorless, and nearly colorless chemical substance. It is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, despite not providing food energy or organic micronutrients. Its chemical formula, , indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. In liquid form, is also called "water" at standard temperature and pressure. Because Earth's environment is relatively close to water's triple point, water exists on Earth as a solid, a liquid, and a gas. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds consist of suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may p ...

Kiteboating
Kiteboating, kite boating or kitesailing is the act of using a kite rig as a power source to propel a boat. Kiteboating is a type of surface water sport, but it also has transportation usesSkysails Captain John Konrad, Mariners Weather Log, April 2009, Volume 53, No. 1, Equipment Kiteboating uses different types of gear from kitesurfing. Kites attached to boats can be larger than kites attached to a surfer. For long voyages, the kite rig must be more autonomously controlled. Due to the lifting power of kites, they are often used with hydrofoils.[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kiteboarding
Kiteboarding or kitesurfing is a sport that involves using wind power with a large power kite to pull a rider across a water, land, snow, sand, or other surface. It combines the aspects of paragliding, surfing, windsurfing, skateboarding, snowboarding, and wakeboarding. Kiteboarding is among the less expensive and more convenient sailing sports. After some concepts and designs that emerged in the late 1970s and early 1980s were successfully tested, the sport received a wider audience in the late 1990s and became mainstream at the turn of the century. It has freestyle, wave-riding, and racing competitions. The sport held the speed sailing record, reaching before being eclipsed by the Vestas Sailrocket. Worldwide, there are 1.5 million kitesurfers, while the industry sells around 100,000 to 150,000 kites per year. Most power kites are leading-edge inflatable kites or foil kites attached by about of flying lines to a control bar and a harness. The kitesurfer rides ...

Surfing
Surfing is a surface water sport in which an individual, a surfer (or two in tandem surfing), uses a board to ride on the forward section, or face, of a moving wave of water, which usually carries the surfer towards the shore. Waves suitable for surfing are primarily found on ocean shores, but can also be found as standing waves in the open ocean, in lakes, in rivers in the form of a tidal bore, or wave pools. Surfing includes all forms of wave-riding using a board, regardless of the stance. There are several types of boards. The Moche of Peru would often surf on reed craft, while the native peoples of the Pacific surfed waves on alaia, paipo, and other such watercraft. Ancient cultures often surfed on their belly and knees, while modern-day surfing is most often ''stand-up surfing'', in which a surfer rides a wave while standing on a surfboard. Another prominent form of surfing is body boarding, where a surfer rides the wave on a bodyboard, either lying on thei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jetboard
A jetboard is a motorized surfboard, where the rider controls the speed using a handheld remote control (wireless or tethered) and uses the bodyweight transfer to maneuver the board. The driveline typically consists of a water jet module (similar to what is found in a PWC), and either a combustion engine or a battery powered electrical motor. Serving as an alternative to standard surfboards, the jetboard also allows differently abled athletes to engage in the sport. Use Jetboards remove the difficulties of conventional surfboards as they can be ridden without wind or waves. There is also no need for paddling, as the boards can be ridden at the touch of a button. Compared to traditional surfing, jetboarding can be easily learned and allows the user to become proficient in a short time. This makes this water sport suitable for a large audience of different physical conditions, ages, experience levels and riding styles. In addition, jetboarding can take place on lakes, rivers, can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jetboat
A jetboat is a boat propelled by a jet of water ejected from the back of the craft. Unlike a powerboat or motorboat that uses an external propeller in the water below or behind the boat, a jetboat draws the water from under the boat through an intake and into a pump-jet inside the boat, before expelling it through a nozzle at the stern. The modern jetboat was developed by New Zealand engineer Bill Hamilton (engineer), Sir William Hamilton in the mid-1950s. His goal was a boat to run up the fast-flowing rivers of New Zealand that were too shallow for propellers. Previous attempts at waterjet propulsion had very short lifetimes, generally due to the inefficient design of the units and the fact that they offered few advantages over conventional propellers. Unlike these previous waterjet developments, such as Secondo Campini, Campini's and the Hanley Hydrojet, Hamilton had a specific need for a propulsion system to operate in very shallow water, and the waterjet proved to be the ...

Flyboard
A Flyboard is a brand of hydroflight sports, hydroflighting device which supplies propulsion to drive the Flyboard into the air to perform a sport known as hydroflying.ExamplesFlyboard Ultimate SupercutPower Board Expert. A Flyboard rider stands on a board connected by a long hose to a watercraft. Water is forced under pressure to a pair of boots with jet nozzles underneath which provide thrust for the rider to fly up to in the air or to dive headlong through the water down as far as one is willing to go.Zapata's outrageous, US$6,600 Flyboard - Aquaman meets Iron Man gizmag.com.

Propulsion
Propulsion is the generation of force by any combination of pushing or pulling to modify the translational motion of an object, which is typically a rigid body (or an articulated rigid body) but may also concern a fluid. The term is derived from two Latin words: ''wikt:pro, pro'', meaning'' before'' or ''forward''; and ''wikt:pellere, pellere'', meaning ''to drive''. A propulsion system consists of a source of mechanical power, and a ''propulsor'' (means of converting this power into propulsive force). Plucking a guitar string to induce a vibration, vibratory translation is technically a form of propulsion of the guitar string; this is not commonly depicted in this vocabulary, even though human muscles are considered to propel the fingertips. The motion of an object moving through a gravitational field is affected by the field, and within some frames of reference physicists speak of the gravitational field generating a force upon the object, but for general relativity, deep the ...

Haemorrhaging
Bleeding, hemorrhage, haemorrhage or blood loss, is blood escaping from the circulatory system from damaged blood vessels. Bleeding can occur internally, or externally either through a natural opening such as the mouth, nose, ear, urethra, vagina, or anus, or through a puncture in the skin. Hypovolemia is a massive decrease in blood volume, and death by excessive loss of blood is referred to as exsanguination. Typically, a healthy person can endure a loss of 10–15% of the total blood volume without serious medical difficulties (by comparison, blood donation typically takes 8–10% of the donor's blood volume). The stopping or controlling of bleeding is called hemostasis and is an important part of both first aid and surgery. Types * Upper head ** Intracranial hemorrhage — bleeding in the skull. ** Cerebral hemorrhage — a type of intracranial hemorrhage, bleeding within the brain tissue itself. ** Intracerebral hemorrhage — bleeding in the brain caused by the rupture o ...
