Helicopter lift........

[technovipin]

can i know the helicopter lift equation, torque produced in the main rotor,rpm variation with the tail and main rotor?

[russ_watters]

There is no simple equation of the form you are asking.

[technovipin]

can i know the difference between propeller blades, helicopter blades and their thrust and lift variation...............

Again, what russ said.

[technovipin]

can i know the calculaiton for the torque produced in the main rotor of the helicopter? and counter torque that has to be given to the tail rotor?
Note:- i am using a 12v motor

[Cyrus]

That is going to be beyond the scope of what you're able to do (based on your posts). Just play around with the tail rotor until you get it to work.

Hi.

This is my first post,
Can any body help me to under stand the total lift force required to fly the helicopter .....
What is the effect of Rotor RPM on that....................

[Cyrus]

Did you not read the very first reply by Russ?

Looks like a language problem. But try this (http://catdir.loc.gov/catdir/samples/cam032/99038291.pdf)
