Interactive Jet Engine Structure.

• Cold Air Intake - The engine is moving through the air so we can think of it as being stationary and the cold air moving toward it at this speed.
• Hot Air Exhaust - The hot exhaust gases exit the engine through a tapering exhaust nozzle. Just as water squeezed through a narrow pipe accelerates dramatically into a fast jet (think of what happens in a water pistol), the tapering design of the exhaust nozzle helps to accelerate the gases to a speed of over 2100 km/h (1300 mph). So the hot air leaving the engine at the back is traveling over twice the speed of the cold air entering it at the front—and that's what powers the plane.
• Long Axle - The turbine blades are connected to a long axle (represented by the middle gray line) that runs the length of the engine. The compressor and the fan are also connected to this axle. So, as the turbine blades spin, they also turn the compressor and the fan.
• Front Fan - A fan at the front sucks the cold air into the engine and forces it through the inlet. This slows the air down by about 60 percent and its speed is now about 400 km/h (240 mph).
• Combustion Chamber - In the combustion chamber, just behind the compressor, the kerosene mixes with the compressed air and burns fiercely, giving off hot exhaust gases and producing a huge increase in temperature. The burning mixture reaches a temperature of around 900°C (1650°F).
• Compressor Fan - A second fan called a compressor squeezes the air (increases its pressure) by about eight times, and this dramatically increases its temperature.
• Exhaust Fan - The exhaust gases rush past a set of turbine blades, spinning them like a windmill. Since the turbine gains energy, the gases must lose the same amount of energy—and they do so by cooling down slightly and losing pressure.
• Kerosene - Kerosene (liquid fuel) is squirted into the engine from a fuel tank in the plane's wing.
