The word “rocket” can mean different things. Most people think of a tall, thin, round vehicle. They think of a rocket that launches into space. “Rocket” can mean the type of engine. The word may also mean the vehicle that uses that engine.

A rocket is a missile, spacecraft, aircraft, or other vehicle that obtains thrust from a rocket engine. The exhaust of the rocket engine is completely propellant carried within the rocket before use. Rocket engines work through the action and reaction and push the rockets forward, simply releasing exhaust in the opposite direction at high speed can therefore work in the vacuum of space.

In fact, rockets work more efficiently in space than in the atmosphere. Multi-level rockets are able to develop the output speed of the Earth and, therefore, can reach unlimited maximum altitude. Compared to air breathing engines, rockets are light and powerful and can generate large accelerations. To control their flight, rockets rely on momentum, aerodynamic profiles, auxiliary jet engines, thrust, inertial wheels, exhaust flow, fuel flow, rotation and/or gravity.

When Were Rockets Invented?

The first rockets known to us were used in China in the 1200s. These rockets were used for fireworks. Armies also use them in wars. Over the next 700 years, people will make bigger and better solid rockets. Many of them are also used for wars. In 1969, the United States launched the first men to land on the moon using a Saturn V rocket.

How Does the Rocket Engine Work?

Like most engines, rockets burn fuel. Most rocket engines convert fuel into hot gas. The engine turn the fuel into hot gas. Gas makes the rocket move forward.

A rocket is different from a jet engine. A jet engine needs air to operate. The rocket engine does not need air. The rocket engine works in space where there is no air.

There are two main types of rocket engines. Some rockets use liquid fuel. The main engines of the space shuttle orbiter use liquid fuel. The Russian Soyuz uses liquid fuels. Other rockets use solid fuels.
