Function of the compressor in a gas turbine engine
Would a jet engine need the compressor?
All heat engines require a compression step, only in turbomachinery the part involved is called compressor. But other engines also compress a medium as part of ...

Function of the compressor in a gas turbine engine
I think that both a practical and a thermodynamic answer can be given.
As far as I understand it, the reasons are twofold.
Correct
From a practical point of view, compressing the air before the ...

Function of the compressor in a gas turbine engine
In order for a jet to create thrust, pressure must be created so the difference in pressure from the inside of the engine to the outside air will create a flow of a certain mass at a certain velocity.

Function of the compressor in a gas turbine engine
You don't. A (sc)ramjet doesn't have a compressor, as the forward velocity of the jet provides the necessary pressure.
Most thermal engines do work by expanding a gas. In many cases, this gas expands ...

Function of the compressor in a gas turbine engine
The reason is thermodynamics: without the compressor, the power output of a gas turbine would be exactly zero. It's not about being "more efficient" but about fundamentally being able to ...

Function of the compressor in a gas turbine engine
The compressor raises the pressure and temperature at which the fuel is burned, thereby increasing the thermodynamic efficiency of the cycle (Brayton) on which the jet operates.
Second, without the ...
