Rocket

The rocket is a vehicle for space, missile, or a vehicle flying a rocket to get a boost through a reaction against the rapid discharge of fluid material from a rocket engine output. Action of the output in the combustion chamber and nozle developer, able to make the gas flow with hypersonic speed, giving rise to a large reactive thrust to the rocket (comparable to the respondent in accordance with Newton’s Law of Movement to 3). Often the definition of a rocket used to refer to rocket engines.
Rocket began to military use and recreation in the 13th century BC. Intensive use of rockets for military, industrial and science began in the early 20th century, where rocketry technology capable of delivering the human race into space era, including humans deliver step foot on the moon.
Rockets used for fireworks, weapons, rescue chair, launch vehicles for artificial satellites, spacecraft, and exploration to other planets. Although less efficient low at speed, rocket capable of delivering incredible acceleration and reach very high speeds with acceptable efficiency.
Chemical rockets store large amounts of energy in the form of an easily removed and can be very dangerous, but the design, test, manufacture and use of a cautious can minimize risk.
Different sizes from small model rockets that can be bought as fireworks, or a hobby rocket, to a large Saturn V used for the Apollo program.
Most current rockets are chemical rockets. This rocket engine requires a solid or liquid fuels, such as liquid fuel booster / amplifier and the space shuttle main engines are used to escape from Earth’s gravity. At the start chemical reaction in the combustion chamber with fuel (with air or oxygen when in space) and the resulting hot gas flow with high pressure out through the channel toward the back of the rocket. Gas pressure is gushing out is what produces the thrust for the rocket so that the rocket can move forward or upward.
There is another concept that the type of rockets used in space are ion thrusters, which uses electromagnetic energy instead of energy from chemical reactions. Nuclear thermal rockets have also been built, but never used.

The use of outer space for

For the exploration of outer space that are not air it must bring their own rocket fuel and oxygen to produce the required thrust.

 Use for military

In military terms, referring to the explosive rocket booster without control devices. These rockets can be launched by ground attack aircraft (air-to-surface rockets), fired from the surface (land / sea) to the target in the air (surface-to-air), or can be fired from the surface (land / sea) to the target surface to another. When the Vietnam war era, there are also ground-air rocket out of control designed to attack aircraft flying in a rocket similar to the control formation.Bullet with different control systems to increase the likelihood of the target.

History of rockets

In ancient times

The earliest known written form of the formula for making gunpowder, Zongyao Wujing, in 1044.
Availability of black powder (gunpowder) to push the projectile is a pioneer of the first development of solid-fuel rocket. In the ninth century Chinese Taoist chemical Experts found a black powder when you’re trying to create a youthful drug (elixir of immortality). This accidental discovery led to experiments in the form of weapons such as bombs, cannon, incendiary fire arrows and fire arrows booster incendiary rockets. The discovery of gunpowder was estimated experimentally century alchemical products.

Rockets in the early days of China.
Exactly when the first flight of the rocket occurred is contested. Some say that the first recorded use of rockets by the Chinese in battle in 1232 against the Mongols. There have been reports of fire arrows and ‘iron pots’ that can be heard to 5 League (25 km or 15 miles) when they exploded because of a collision, causing devastation to a radius of 600 meters (2,000 feet), apparently caused by shrapnel. The decrease in iron pots may be a way for a besieged army to blow up the attackers. Fire arrows with explosive arrows either inherent, or an arrow driven by gunpowder, such as Korea Hwacha.
More information is controversial, noting that one of the earliest devices using internal combustion rockets are rat-land, a kind of fireworks, which are recorded in the 1264 scare, the Queen Mother Kung Sheng at a party held in his honor by his son Emperor Lizong .
Furthermore, one of the early texts that mention the use of rockets adalahHuolongjing, written by Chinese artillery officer Jiao Yu in the mid-14th century. This text also mentions the first known use of multi-stage rocket, the ‘fire-dragon out of water “(shui huo long chu), which is used mostly by the Chinese Navy.

 Spread of rocket technology

Genghis Khan (Mongol) deploy the technology of china
Rocket technology first became known to Europeans following their use by the Mongol leader Genghis Khan and Ogadai Khan when they conquered most of Russia, Eastern Europe, and Central Europe. Mongolia has acquired the technology to conquer northern China and also by workers of Chinese rocketry experts as mercenaries for the Mongol military. Reports of the Battle of Mohi in 1241 described the use of rocket-like weapons by the Mongols against the Magyars. Rocket technology also spread to Korea, in the 15th century with hwacha wheeled rocket that will launch Shin Ki Chon.
In addition, the spread of rockets to Europe was also influenced by the Ottomans at the siege of Constantinople in 1453, although it is likely that the Ottomans themselves be influenced by several centuries before the Mongol invasion. In their history of rockets published on the Internet, NASA says “Rockets appear in Arab literature in 1258 AD, describing Mongol invasion using a rocket on February 15, to seize the city of Baghdad.
Between 1270 and 1280, Al-Hasan al-furusiyyah Rammah write wa al-al-harbiyya manasib (Book military horseback riding and Ingenious War Tool), which included 107 gunpowder recipes, 22 of which are for rockets.  According to Ahmad Y Hassan, Al-Rammah recipe is more explosive than rockets in use in China at that time.
The rocket’s name comes from Italy Rocchetta (ie little fuse), the name of a small firecracker created by the Italian artificer Muratori in 1379.
Between 1529 and 1556 Conrad Haas wrote a book in which he described the rocket technology, which involves a combination of fireworks and weapons technology. The manuscript was discovered in 1961, the public records of Sibiu (Sibiu public records Varia II 374). His work deals with the theory of multi-stage rocket motion, a mixture of different fuels using liquid fuel, and introduced the Delta and the fin-shaped bell-shaped nozzle.
At the end of the 18th century, rockets were used in warfare in India against the British, who took and enhancing them further in the 19th century. The main character in the field of rocket when it was William Congreve. From there, the use of rockets military spread throughout Europe. Red light rocket inspires U.S. national anthem, The Star-Spangled Banner.
Rocket when it’s very inefficient. Goddard began when Robert modern rocket put a funnel de Laval in rocket engine combustion chamber, doubling the thrust and improve efficiency, opening the possibility to travel vertically into the sky. This technique was then used on the V-2 rocket designed by Wernher Von Braun who became a major player in advancing modern rocket. V2 is used extensively by Adolf Hitler in the final phase of World War II as a weapon of terror to the inhabitants of England, every successful launch towering into the sky marked the beginning of Space Age.
