How Helicopter works...

[Moses]

Well, I know this Q might look cheesy or silly...but:
What is the major equation which decides if X disc with Y raduis with Z angular acceleration will carry M mass and "fly" with it...I am just concern about vertical movements...not the horizantal....Basically its about a hgelicopter moving in one dimension "up"

Cheerz

I'm not sure about your wording there, but a helicopter rotor blade is just a wing. The speed of the blade at any point depends on its radius and rpm, then with that, you can calculate the lift.

Can you give me the equation of the left please?

Thx for help.
