Closing Pin
A closing pin is a curved piece of stainless steel metal used in the sport of skydiving. The pin is sewn onto the bridle, which is a 7- to 10-foot-long piece of nylon webbing connected to the pilot chute. The closing pin passes through the closing loop and in doing so, secures the main container of a skydiving rig, keeping the parachute from deploying prematurely. When the pilot chute is thrown out by the skydiver and catches air, it pulls the closing pin from the closing loop and allows the main parachute to be released from the container and inflate. Fashion Because the closing pin is seen by many skydivers as a life-saving piece of equipment, it has become a symbol of the sport for those who have experienced only one tandem jump Parachuting, including also skydiving, is a method of transiting from a high point in the Atmosphere of Earth, atmosphere to the surface of Earth with the aid of gravity, involving the control of speed during the descent using a parachut ... an ...

Stainless Steel
Stainless steel is an alloy of iron that is resistant to rusting and corrosion. It contains at least 11% chromium and may contain elements such as carbon, other nonmetals and metals to obtain other desired properties. Stainless steel's corrosion resistance, resistance to corrosion results from the chromium, which forms a Passivation (chemistry), passive film that can protect the material and self-healing material, self-heal in the presence of oxygen. The alloy's properties, such as luster and resistance to corrosion, are useful in many applications. Stainless steel can be rolled into Sheet metal, sheets, plates, bars, wire, and tubing. These can be used in cookware, cutlery, surgical instruments, major appliances, vehicles, construction material in large buildings, industrial equipment (e.g., in paper mills, chemical plants, water treatment), and storage tanks and tankers for chemicals and food products. The biological cleanability of stainless steel is superior to both alumi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skydiving
Parachuting, including also skydiving, is a method of transiting from a high point in the atmosphere to the surface of Earth with the aid of gravity, involving the control of speed during the descent using a parachute or parachutes. For human skydiving, it may involve a phase of more or less free-falling (the skydiving segment) which is a period when the parachute has not yet been deployed and the body gradually accelerates to terminal velocity. For cargo parachuting, the parachute descent may begin immediately, such as a parachute-airdrop in the lower atmosphere of Earth, or be significantly delayed, such as in a planetary atmosphere where an object is descending "under parachute" following atmospheric entry from space, and may begin only after the hypersonic entry phase and initial deceleration that occurs due to friction with the thin upper atmosphere. History Common uses Parachuting is performed as a recreational activity and a competitive sport, and is widel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pilot Chute
A pilot chute is a small auxiliary parachute used to deploy the main or reserve parachute. The pilot chute is connected by a bridle to the deployment bag containing the parachute. Pilot chutes are a critical component of all modern skydiving and BASE jumping gear. Pilot chutes are also used as a component of spacecraft such as NASA's Orion. Deployment methods Spring-loaded The spring-loaded pilot chute is used in conjunction with a ripcord. When the user pulls the ripcord, the container opens, allowing the pilot chute compressed inside and loaded with a large spring inside it to jump out. Spring-loaded pilot chutes are mainly used to deploy reserve parachutes. They are often also used to deploy the main parachute on skydiving students' parachute equipment. They are also commonly used in drogue parachute in cars or in planes such as the B52 Bomber. Pull-out The pull-out and throw-out pilot chutes are identical in construction; the difference is in their connection to th ...

Parachute
A parachute is a device used to slow the motion of an object through an atmosphere by creating drag or, in a ram-air parachute, aerodynamic lift. A major application is to support people, for recreation or as a safety device for aviators, who can exit from an aircraft at height and descend safely to earth. A parachute is usually made of a light, strong fabric. Early parachutes were made of silk. The most common fabric today is nylon. A parachute's canopy is typically dome-shaped, but some are rectangles, inverted domes, and other shapes. A variety of loads are attached to parachutes, including people, food, equipment, space capsules, and bombs. History Middle Ages In 852, in Córdoba, Spain, the Moorish man Armen Firman attempted unsuccessfully to fly by jumping from a tower while wearing a large cloak. It was recorded that "there was enough air in the folds of his cloak to prevent great injury when he reached the ground." Early Renaissance The earliest evidence f ...

Tandem Jump
Parachuting, including also skydiving, is a method of transiting from a high point in the Atmosphere of Earth, atmosphere to the surface of Earth with the aid of gravity, involving the control of speed during the descent using a parachute or parachutes. For human skydiving, it may involve a phase of more or less free-falling (the skydiving segment) which is a period when the parachute has not yet been deployed and the body gradually accelerates to terminal velocity. For cargo parachuting, the parachute descent may begin immediately, such as a parachute-airdrop in the Troposphere, lower atmosphere of Earth, or be significantly delayed, such as in a planetary atmosphere where an object is descending "under parachute" following atmospheric entry from outer space, space, and may begin only after the hypersonic entry phase and initial deceleration that occurs due to aerodynamic drag, friction with the thin upper atmosphere.

Military Sports
Military sports are sports practiced by the military. They are the subject of international competitions, such as the Military World Games, with an objective relating to the physical training of military. Particular sports may be chosen to improve combat readiness, skill, toughness, the development of physical qualities of the warfighter, and professional proficiency based on the different areas of the military action: land, sea and air. History In 1858 Archibald MacLaren opened a gymnasium at the University of Oxford, England and in 1860 instituted a training regimen for 12 non-commissioned officers and their officer Major Frederick Hammersley at the university. This regimen was assimilated into the training of the British Army, which formed the Army Gymnastic Staff in 1861 and made sport an important part of military life. In the United States, the first Inter-service Sports Council (ISSC) meeting was held in 1947. Today, Armed Forces Sports in the U.S. are run through th ...
