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.
The tail rotor of a helicopter serves three primary functions: it counteracts the torque produced by the main rotor, preventing the helicopter from spinning uncontrollably in the opposite direction. It also provides directional control by allowing the pilot to adjust the yaw, enabling the helicopter to turn left or right. Additionally, the tail rotor contributes to stability during flight, helping maintain the helicopter's orientation and balance.
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.
The small rotor on the tail, called the tail rotor, counteracts the torque produced by the main rotor of the helicopter. Without the tail rotor, the helicopter would spin uncontrollably in the opposite direction of the main rotor. The tail rotor helps maintain the helicopter's balance and heading.
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.
In the helicopter it is turned by the engine, through the transmission. In autogyro it rotates freely with forward movement
