Engines
There are many kinds of engines.
Engines
Turbojets are less efficient than turbofans at lower speeds. They are also very loud.
Turbofans are more efficient and are very quiet. Unlike turbojets, turbofans drive some air into a bypass core while other air is going around it.
Propellers
Regular propellers have no engine behind them.
Turboprops are like turbofans and propellers.
Ramjets
Ramjets work by compressing air, mixing it with fuel, and letting it out at very high speeds. Unlike the other engines, it has no moving parts.
