One of the most common types of jet engines, turbojet engines work in a similar way as automotive combustion engines.
What is the most common type of jet engine?
Turbofan jet engines are powering most of todays airliners. All the air that enters the intake of a turbofan jet engine flows through the generator that produces the hot air. This generator comprises of a turbine, combustion chamber, and compressor.
Which engine is used in jets?

What is the simplest type of jet engine?
A turbojet is the simplest kind of jet engine based on a gas turbine: it’s a basic “rocket” jet that moves a plane forward by firing a hot jet of exhaust backward. The exhaust leaving the engine is much faster than the cold air entering it—and that’s how a turbojet makes its thrust.
Which is better turboprop or jet?
A turbine engine is extremely light and produces tremendous power-to-weight as opposed to a comparable piston engine. … Conversely, jet engines are less efficient than a turboprop but often make up for it by being faster, hence spending less time in the air for the same destination.
Why jet engines are not used in cars?
A jet engine only produces reasonable thrust at very high RPM, lower RPM’s result in high fuel consumption and next to no thrust. … A jet engine has a very high volume and temperature of exhaust gas. Any one of these characteristics make it entirely unsuitable for a motor vehicle.
How does a jet engine start?
The electric motor spins the main shaft until there is enough air blowing through the compressor and the combustion chamber to light the engine. … Fuel starts flowing and an igniter similar to a spark plug ignites the fuel.
