How is the rotor made to turn the helicopter and in an autogyro?
The rotor turns on top of a vertical shaft from the transmission
What is an autogyro?
An autogyro looks like a helicopter with a rotor blade on the top of the fuselage but it also has another propeller in back to push it. The autogyro uses the air passing UP through the rotor blade to turn the main rotor blade and give it LIFT. So it needs something to provide THRUST to propel it forward. An autogyro can NOT take off vertically and go straight up. Instead it must have a take-off roll to get it flying. The main rotor of a helicopter is more complicated and it produces both LIFT and THRUST. Their controls are more complicated and the loads on the blades and blade attachments and the rotor Mast. The Autogyro's blades turns due to air passing through it just like a maple seed "flys" with its single wing as it falls from the tree. Since the main rotor of the Autogyro does not produce a vertical Lift, that means the Mast of the rotor does not carry a torque load. The Mast only supports the weight of the Autogyro. Whereas, the Mast of the Helicopter is experiencing Torque loads and Bending loads(for some types of helicopters) as well as Tension forces by the weight of the helicopter.

How does a helicopters rotor blades make the helicopter turn left and right?
By adjusting the speed of tail rotor, which points to the side, the pilot can turn the helicopter in flight. The main upper rotor actually plays only a minor part in making helicopter turn. The part supplying most of the control is the tail rotor. Because the main rotor is spinning in one direction, without a tail rotor, the body of the helicopter would spin around in circles in the opposite direction. The reason for this is explained in the first part of Newton's third law of motion: for every action there is an equal and opposite action. The torque generated to make the rotor turn also exerts torque on the body of the helicopter "willing" it to spin the opposite direction. However, the tail rotor spins, pushing air to the side. This creates force in the opposite direction, keeping the helicopter stable. By simply adjusting the speed of the tail rotor, the helicopter can be turned in flight.
How a helicopter used of thrust for flying?
The main rotor of a helicopter is actually a set of wings that turn. They produce lift, just like the wings of an airplane. To change direction, the rotor is tilted, and the helicopter is PULLED in that direction.
What is the Difference between the way an Airplane and a Helicopter fly?
To fly, helicopters have a Propeller. Airplanes have an engine that provides thrust to push it through the air, which forces air over the wings and create lift that allows the plane to climb. Helicopters have a main propellor blades that turn about a vertical axis. This large rotor provides the Lift and forward motion to the helicopter. It also has a smaller rotor at the tail that counter acts the torsional forces created by the torque of the main rotor. An autogyro is a type of helicopter that has a propellor that pulls it forward through the air. This forces air to go through the top main rotor(like on a helicopter) and this main rotor produces the lift for the autogryo.
How does an autogyro work?
Though an Autogryro may resemble a Helicopter, they work differently. A helicopter uses a powered shaft to turn it's wings, which are called rotors. These rotors provide lift for the craft and also give the helicopter it's momentum through air.The autogryro uses un-powered rotor blades for lift in what is called auto-rotation together with an airplane style propeller to provide the forward thrust. The combination of the propeller pushing the craft forward causes air to flow over the curved top surface of the rotor, which is spinning because of the air pushing up under it, and the air over the top of the rotor produces the lift.
What is a back rotor of a helicopter used for?
it depends. sometimes they make the helicopter turn. On models when they are facing up like the main rotor, they propell it forward so the gyro can fall to one side and lean the chopper forward. The major purpose of the back rotor is to counteract the torque of the main rotor. On helicopters with a single top rotor, if there were no back rotor, the torque would cause the helicopter to spin around as soon as it lifted off the ground.
Why do helicopters fly so slow?
What is the limiting factor for helicopter speed you ask? What happens to the rotor as the velocity of the helicopter increases? The relative speed of the tips of the rotors changes because of the wind speed. On the advancing side of the rotor the speed increases by the speed of the helicopter. On the retreating side of the rotor the speed decreases by the speed of the rotor. One of two things happens as the helicopter reaches a high speed: A: If it is a large rotor, the advancing blade will reach the sound barrier and sap energy from the rotor, slowing it. Significant damage may occur to the helicopter. B: If it is a smaller rotor, the retreating blade will slow to the point where stall occurs, and the helicopter will be forced into a turn while losing altitude and decreasing speed, then it will usually recover if altitude permits. Option B can be mitigated by increasing rotor RPM at higher speeds. In this case the rotor speed becomes the limiting factor, as the centrifugal forces at the root of the blade are quite incredible.
