SUCK-SQUEEZE-BANG-BLOW!!!!

Whoops! With a title like that you probably think you've hit the wrong website.
While the above title may sound like something out of my writings, it's really just a creative way of remembering the stages of a turbojet engine uses in aircrafts.

Hmmm, that doesn't sound much better, does it?

OK, let's start with the basics.

Most modern passenger and military aircraft are powered by gas turbine engines, which are also called jet engines. The first and simplest type of gas turbine is the turbojet.

In a basic turbo jet, the air enters the front intake (suck) and is compressed by the compressor (squeeze), then forced into combustion chambers where fuel is sprayed into them and the mixture is ignited (bang). The gases which form expand rapidly, and are exhausted through the rear of the combustion chambers and out through the nozzle (blow) providing the forward thrust. Just before the gases enter the engine nozzle, they pass through a fan-like set of turbine blades which rotates the engine shaft. This shaft, in turn, rotates the compressor, thereby bringing in a fresh supply of air through the intake. All of these processes are happening at the same time.
