What cancels torque?
The tail rotor cancels out torque in a helicopter generated by its engines and main rotor. Without this, the helicopter would simply spin in a circle and be complete uncontrollable.
How counter propellors work?
Counter-propellers (proper name contra-rotating propellers) work by spinning in opposite directions. This cancels out torque in the same way as a helicopter uses rotors to cancel torque.
What is the function of anti-torque rotor of a helicopter?
To counteract the force of torque created by the main rotor. If not for that tail rotor, the torque would cause the helicopter to spin continuously around.
Why is it necessary to have the tail rotor on the helicopter that spins perpendicular to the spin of the main rotor?
"For every action there is an opposite and equal reaction." For the helicopter to make the blade move in one direction, the blade will try to make the helicopter move in the opposite direction. Since the blade tries to make the helicopter spin, something is needed to keep the helicopter from spinning. So the manufacturer puts a tail rotor on the helicopter.
What do pedals in a helicopter do?
The anti-torque pedals in a helicopter are used to keep the heli from rotating from the spin of the rotors (it controls the tail rotor)
What is the second rotor on a helicopter for?
The small rotor on the tail is to counter-act the torque of the big rotor on top. So it is used for steering and to keep the helicopter stable.
For a helicopter to be stable as it flies it must have at least two propellers. why?
Helicopters require at least two propellers to achieve stability through a concept known as "counter-torque". The main rotor produces torque that would rotate the body of the helicopter in the opposite direction. The tail rotor or fenestron is used to counteract this torque, providing stability by keeping the helicopter from spinning uncontrollably.
How much torque does tail rotor needs to work?
The amount of torque required by a tail rotor depends on factors such as the size and weight of the helicopter, the speed at which it's flying, and external forces like wind. Generally, tail rotors are designed to provide enough torque to counteract the torque produced by the main rotor and maintain stable flight.
What would happen to a helicopter if it didn't have a tail rotor?
The torque from the main rotor would cause it to spin uncontrollably.
Can you compare a size of an elephant to something?
it is bigger that a helicopter
Why do some helicopters have a small tail rotor?
Tail rotors are to correct the effect of engine torque and help steer the helicopter
What is the purpose of the helicopter tail propeller?
To counteract the torque of the main rotor and to provide yaw movement along the z axis.
