What is the principle of turbojet?
A turbo jet is a jet engine that is used on planes that go faster than the speed of sound (768 mph). A turbojet starts by having compressor fans which compress the air that en…ters the engine, then that compressed air gets mixed with jet fuel in the combustion chamber which burns, then that burned air goes out of the combustion chamber and turns the turbines which takes some of the energy away from the exhaust. the turbines are attached to the compressor fans, so when the turbines spin, so do the compressor fans.

Why are turbojet engines so noisy?
Turbojet engines, like any turbine engine are always very noisy because of the way they work. Turbine engines do not have an enclosed combustion chamber like other engines,… rather they have a fairly open-ended system. As burning fuel creates heat and expansion, it is used to propel an impeller which thus generates thrust. This system is highly dependent on air being able to quickly and easily enter and exit the engine in very high volumes. It is not possible to reduce the engine noise without also constricting this airflow and thus reducing the power output. It is possible to make quiet turbojet engines, but making them quieter also makes them heavier and less powerful as well as reducing fuel efficiency. Turbojet engine and aircraft designers must walk a fine line between noise reduction and performance. (MORE)

How does a turbojet engine work?
Axial Turbojet; Air enters the engine and goes through a compressor, increasing the air's pressure and temperature. The air then enters the combustor where it is mixed with fu…el and ignited. Next, the hot gas expands and spins the turbine which powers the compressor. Finally, the exhaust passes through a convergent nozzle into the atmosphere, creating a high velocity jet which pushes the aircraft. Centrifugal Turbojet; Nearly the same as an axial-flow turbojet, the centrifugal-flow turbojet compresses the air by diverting it from the axis of flow. While this type of jet is simpler, lighter and cheaper than axial-flow, it is less efficient and can not handle as high a volume of air. Often a combination of axial and centrifugal compressors are used in modern jets. (MORE)

Is a turbojet engine the same as a jet engine?
Nothing, the are the same thing. Jet is just the shorter way of saying it. However, there is a difference between a turbofan and turbojet. A turbofan has a large fan at the …front of the engine where as a turbojet doesn't have this fan. Turbofans are mainly used in modern commercial airliners where as turbojets were used in older commercial airliners and are now used on fighter jets. (MORE)

How does a turbojet provide power to aircraft?
A turbojet consists of an air inlet, an air compressor, a combustion chamber, a gas turbine and a nozzle. Through this constructions, the turbojets provide power to an aircraf…t when the air is compressed into the chamber, heated and expanded by the fuel combustion and then allowed to expand out through the turbine into the nozzle where it is accelerated to high speed to provide propulsion.
