How a jet engine really works: 4 simple steps: 1) Compress air. 2) Release it into a partially enclosed space. 3) Heat it up. 4) Release it through a nozzle. Copyright 2009, Lawrence Henry Berg. #2 the diffuser directs the hot compressed air and releases it into the combustion chamber. It's volume increases as the pressure and temperature go down. #3 fire increases the temp and pressure in the new volume! Get it? Now #4 (the nozzle) will determine the pressure and temp and flow rate as it's released. ---- I've listened to thousands of explanations in 50 years but never really understood how it works or how to explain it. So this is my way of understanding it, and it works!
