What is the purpose of the back propeller on a helicopter?

The role of the tail rotor It ensures that the torque produced by the main rotors is properly compensated for by ‘pushing’ the chopper in the opposite direction of the torque. By doing this, it ensures that the chopper doesn’t wobble and remains stable in flight.

What is the long tube on a helicopter?

The hose is extended from either the refueling “boom” extending under the airplane’s lower fuselage (e.g., KC-10, KC-135) or one of the aerial fueling pods mounted on the underside of the wings, between the two engines on either wing (e.g., KC-130).

What is the function of the tail rotor in a helicopter?

Similar to the main rotor of the helicopter, the tail rotor also produces lift to the blades of the tail rotor due to the pressure difference. But in this case, lift is horizontal. The Tail rotor simply pushes the tail of the helicopter in the opposite direction of the torque & prevents the rotation of the helicopter.

What is the fan at the tail of a helicopter called?

That small fan at the tail of the helicopter is known as the tail rotor. The tail rotor is very important in a case of helicopters. Without a tail rotor, it will become almost impossible to control the helicopter. Before going to tail rotors lets take a look at how helicopter gets a lift?

What is a tail rotor on a Puma helicopter?

Traditional tail rotor of an Aérospatiale Puma (Image Credit: By Darz Mol / Wikimedia Commons) The tail rotor is a vertical (or near-vertical) set of blades mounted at the end of the tail of the chopper.

Why does a helicopter have a small propeller on the end?

Your first thought might be that the small propeller (rotor) on the end is for steering the helicopter, but it’s not. It is there because of Newton’s Third Law: For every action, there is an equal and opposite reaction. Let’s start with a simple example: a person pulling on a rope attached to a wall.
