Remarkably, a modern jet engine can look and function a lot like a big
propeller.

Remarkable only to the clueless like yourself, ass hat.

You could put down that tube of glue you have been sniffing, ass hat,
and use it to build one of these and maybe learn something most 10 year
old boys know:

Fan jets have been around since 1942.Built by GE in Lynn Ma. TreBert

Ram jet is the fastest.It wants to go faster and faster.It in reality compresses more and more the faster it goes. Here is its draw back.It uses up its fuel faster and faster.Still I like it for it has very simple engineering.I have a killer fighter jet using one.Up for the kill down to fuel up.Its as close to being a rocket a jet can get. No fan No prop. just breath and burn and away you go.

I used 'ramjet' in Words With Friends
the other day, adding the 'ram' to hit
a triple word, and my opponent
commented 'that's a new word'.
No, I said, it's the original word.
It was shortened to 'jet'.

Is there any aspect of the article from which you gained some
knowledge, jimp?

Remarkably, a modern jet engine can look and function a lot like
a big propeller.
