Rockets

Some facts

Rockets are used for many thing to going up to space or for fireworks. Rockets were made in 1100 by the Chinese. Rockets were also improved by the British.

The definition

A rocket is a missile, spacecraft, aircraft or other vehicle obtains thrust from a rocket engine.

Efficiency

Rockets are relatively lightweight and powerful, capable of generating large accelerations and of attaining extremely high speeds with reasonable efficiency.

Types of rockets

Chemical rockets are the most common type of high performance rocket and they typically create their exhaust by the combustion of rocket propellant. Solid-fuel rockets are the oldest and simplest of the types of rockets use solid fuel for thrust.

History of rockets

The Chinese began experimenting with the gunpowder-filled tubes. At some point, they attached bamboo tubes to arrows and launched them with bows. Soon they discovered that these gunpowder tubes could launch themselves just by the power produced from the escaping gas. The true rocket was born.

World War II

In 1943, production of the V-2 rocket began in Germany. It had an operational range of 300 km (190 mi) and carried a 2,200 pound warhead, with an amatol explosive charge.

The Cold War

Rockets became extremely important militarily as modern intercontinental ballistic missiles (ICBMs) when it was realized that nuclear weapons carried on a rocket vehicle were essentially impossible for existing defense systems to stop once launched, and ICBM/Launch vehicles such as the R-7, Atlas and Titan became the delivery platform of choice for these weapons.

Modern day

Rockets remain a popular military weapon. The use of large battlefield rockets of the V-2 type has given way to guided missiles. However rockets are often used by helicopters and light aircraft for ground attack, being more powerful than machine guns, but without the recoil of a heavy cannon and by the early 1960s air-to-air missiles became favored.

Modern rocketry

Modern rockets were born when Goddard attached a supersonic nozzle to a liquid-fueled rocket engine's combustion chamber.

NASA

The National Aeronautics and Space Administration (NASA) is the agency of the United States government that is responsible for the nation's civilian space program and for aeronautics and aerospace research.

How rockets work

In a rocket, fuel is burned in oxygen in a combustion chamber to produce a mass of hot gases. The gases expand and stream backwards out of the rocket. The force as they stream out backwards sets up a reaction force in the opposite direction, called thrust, which propels the rocket forwards.
