The Jet engines purpose is to create thrust.With out Thrust a plane would not be able to fly.
yes they are, they are the engines you see on a 747 or even a small Private jet
yes
No. Jet engines draw oxygen from the atmosphere to mix and burn with jet fuel, and cannot function in a vacuum. Rockets carry their own oxygen, and can travel in the vacuum of space.
Jet fuel is injected into high pressure air in jet engines.
A pulse jet engine is one of the most simple and efficient propulsion devices ever designed. There are three types of pulse jet engines: The valved pulse jet, the valveless pulse jet, and the upright or "Jam jar jet". For complete details on pulse jet engines, go to wikipedia.org and search "Pulse Jet Engine".
The jet engines used jet fuel, not gasoline as the 6 main engines did.
An aircraft propelled by jet engines rather than piston engines.
Many factories in Britain make jet engines.
jet engines require air, compression, and combustion to make it work
A jet plane is any aircraft powered by jet engines.

None. Jet engines don't have cylinders. While Jet engines don't have cylinders they have combustors (which can also be called combustion chambers). Due to turbulence and other problems early jet engines had multiple small combustors, most modern jet engines have only one large combustor as it is simpler to build. some jets have combustion 'cans' which are cylinders but have no moving parts within
It is the height, width and length of a jet engine.

It isn't a matter of why they need it! Some planes are just designed with jet engines! Jet engines take a small amount of air and push it out fast whereas props take a large amount of air and push it back slower! Some planes just have jet engines!
No they're not safe. Jet engines are very dangerous and extremely powerful. They can take your whole body if you get to close. Don't get so close if the aircraft engines are on.
