Hi Chris

Here is the short version of what happens in the afterburner: The afterburner is situated after the engine and therefore all the hot air from the engine is passing through the afterburner. When you ignite the afterburner a lot of fuel is sprayed into the hot air and ignited. This creates quite a bit off excess thrust, but is not very economical. You can probably find more info on the net.

[Question about jet engine mechanics. The term "After Burn", I think I have a general concept that massive amounts of fuel is dumped within the engine to produce a surge in thrust. I'd like to more details (on the level of a mechanical engineer) on really how a jet engine works and really what happens when the "After Burner" kicks in. I don't expect a dissertation or thesis, I just want to know more about the how it works.

Thank you,
Keep up the great work RUN,
