how does a helicopter work.how does its rotter controls its movement?

Answer 1

The answer to your question is very complex. You have to first understand how it generates lift and creates stability. Then you have to understand the controls (the cyclical and collective levers).

Here is the Wiki page for more info: http://en.wikipedia.org/wiki/Helicopter

Answer 2

The rotor is shaped like an aircraft wing.

An aircraft wing generates lift when it moves forward through the air. The rotor blade generates lift in exactly the same way that an aircraft wing does, except that the engine rotates it forward. When the blade starts going backward a complicated linkage flips it so it generates lift going that way too.

As the engine turms, the helicopter tries to rotate the other way. The tail rotor stops it from doing that.

Answer 3

The main rotor provides the lift and when angled the forward motion for the helicopter. The tail rotor is to offset the torque of the main rotor to prevent the helicopter from spinning in circles about the axis of the main rotor.

Answer 4

Must use the devoted to the boundary conditions ,the torsional ,pressure and axially compressive loads ,as the eight sets of considered and the critical load , clamped shells subjected and more many aspects
