| MAIN PROPULSION COMPONENTS | ||
Looking at the design more closely, you can see the parts of a rocket previously discussed: the combustion chamber and the nozzle. Up at the top of the diagram are the tanks, which hold the fuel and the oxidizer. Everything else on the diagram is simply there to move the fuel and the oxidizer from the tanks to the combustion chamber. Such construction is not an easy task, but is necessary when greater control of the rocket thrust is required. Most of the huge rockets that hurl the astronauts and satellites into space use liquid fuels like kerosene or super-cold, liquid hydrogen and oxidizers like liquid oxygen. When the two liquids are sprayed into the combustion chamber, they ignite and burn with an explosive force. |
