but can somebody please explain to me how they would answer the question when asked
"Explain to me briefly how the CFM engine operates"?
depends on who is asking the question and their level of knowledge
All the answers above are correct so pick and choose
I'll try another suitable for a wife or girl friend.
The engine has spinning blades inside it like a window fan or your hairdryer and these blades propel heated air out the back like a watering hose does with water. The jet propel out the back pushes the engine, hose etc. and what is attached to it.
You can probably get the same effect with your electric hairdryer by turning it to high and laying it down on the bathroom counter and watch it spin across the counter.
Please do not do this while taking a bath
