i need to understand how how helicopters work,anyone know?
Welcome to PF,
To what level do you need to go? Is it for a project? Have you tried searching on the Internet? Perhaps, this would be more appropriate in the engineering forums and one of the mentors would be kind enough to move it?
If you have specific questions, ask away. I echo Hoot's question. To what level of detail do you want to go?
Here's a pretty good site.
Well, the blades are like wings, and they spin round, and the helicopter goes up.
Otherwise, same answer as the others gave.
Separate names with a comma.
