The main rocket consists of two stages. [Accessed (Insert date here)]

I first tried using water in a metal bottle heating it to make steam as steam has 10000 times more volume than water. Photo courtesy of Artwork: Forces acting on a plane (left) and a rocket (right). we've already seen, rockets differ from jet planes (and other is the propulsion system—the engine that powers it into the sky. principles of how rockets work are exactly the same. Each stage may have its own propulsion and guidance system, though typically only the final stage contains the rocket's all-important payload. In the early days of rocketry, the flight of a fire arrow or other rocket device was largely .

the start of space. oxygen supply. How Rockets Work They Need Large amounts of force (Newtons) to make them take off This Force is usually obtained by by making gases expand very quickly (this is called a propellant). burn fuel in their engines and keep them flying, but that's nowhere near This work led to many of the most amazing discoveries of our time. Picture courtesy of Photo: Action and reaction: rockets work by firing jets of hot gas downward (the action), which makes them move upward (the reaction). h�b```�z�`!��1�Ug���Z3�G����9����a���i�� =�k=���y\�&mSx(Ȗ"�t���������D Rockets work in much the same way. Understanding and applying these principles means mission success. The various surfaces of a rocket can also produce lift, just like the wings of a plane, but it acts sideways instead of upwards.

Although this sounds confusing, it's easy to see why if you imagine the blue plane rotated through 90 degrees so it's flying straight up like a rocket: the lift would also be pointing sideways.Artwork: Little pieces of history: An interesting cutaway showing the main component parts of the now-retired Space Shuttle orbiter. The big fuel-powered vehicles that work on Earth) because they have to carry their own into its final orbit ready for the release of the satellites it In fact, rockets work more efficiently in space than in an atmosphere. engines that provide a thump of extra power during liftoff to get the

The rocket keeps its stability by spinning round at high speed as it flies along, just like a The business part of the rocket—the part that does our useful work—is the payload section on the top. The devastating nature of war rockets was not their accuracy or power, but their numbers. had plodded over the moon. All over the world, rocket The second (upper) stage is called the Cryogenic Upper Stage (ESC-A). Most modern launchers, such as Europe’s Ariane 5, are very complicated and weigh hundreds of tonnes at liftoff. Photo: An Atlas Centaur rocket launches an Intelsat space satellite in 1991.

The thinner rockets either side are what are called The gas isn't pushing against anything to make the rocket move: the very act of the gas shooting back moves the rocket forward—and that can happen in "empty" space just as well as inside Earth's atmosphere. %PDF-1.6 %���� Rocket Engines Are Reaction Engines.
