Thisprinciple can be complicated but I'll try to make it so you understand.
There are four phases to a jet engine
1) Intake
2)Compression
3)Ignition (Combustion)
4)Exhaust
1) Intake
This portion is what you see when you're looking straight at the engine from the front. The fan blades you see we'll get into later, however you can imagine air being forced into the engine from this stage.
2)Compression
At this point the air that made it into the engine goes through a serious of smaller fan blades, similar to what you see when looking at the engine. These smaller blades compress (compact) the air.
3)Ignition
At this point, when the air has been compressed it is moved into a chamber where jet fuel is squirted into the mixer using spray nossels. Also at this stage is an igniter which creates the spark to light the fuel air mixture.
4)Exhaust
At this point the air is heated and forced towards the rear of the engine. At this point it goes through another series of fan blades while it decompresses. After the remaining exhaust fan blades it exits the engine through the rear.
Now... why so man fan blades inside the engine?
Lets start with the small ones that compress the air. These help make a ratio of compressed air to fuel for proper burning.
The exhaust fan blades are used to turn the large fan blade you see when looking at the engine from the front. So when the air turns the exhaust blades, that is linked up through a straight shaft that turns the giant fan blade. This moves air through the engine AND also through the engine cowling. Depending on the engine 80 percent of the forced air goes through the engine and the other 20 percent flows over the engine and propells the aircraft forward.
Both a balloon and jet engine exert force in the backward direction to move forward.
The exhaust gases from combustion create thrust which pushed the plane in the other direction
A jet plane uses a jet engine's thrust for propulsion. A propeller is a set of blades somewhat like a big fan that blows air to the back of the plane for thrust instead of using a jet engine for the thrust to move the plane forward.

This is a very good question. Squids move through the water at high speeds using a jet propulsion-like organ called a "siphon". What the siphon does is take in water and thrust it out, much like a jet engine. The end result is the jet-like streamline of a squid.
Frank Whittle was the invetor of the jet engine.
You can but a mini jet engine on ebay.
A Pulse Jet is a type of jet that uses a pulse jet engine for propulsion. The jet engine works by using pulse combinations of combustion. This is called "resonant combustion". The engine requires very little moving parts.
it depends on how old the engine is a steam engine is old so it would more than likely be shaft
The Germans invented the first operational jet engine during WW2.
When a jet plane moves on land, it is called taxiing. The engine thrust of the plane allows the plane to move without actually taking off until it is ready.
