The tail rotor is used to counter act the torque along the main rotor axis (yaw). This results in a net force to one side, so a true hover requires a helicopter to lean a bit towards the thrust side of the tail rotor.azabak said:How does an helicopter counteract the torque generated by its blades? And the tail blades, what are they for?
sophiecentaur said:For the best description, ever, of all this, read the first couple of chapters in 'Chickenhawk' by an ex Vietnam Chopper pilot. He describes learning to fly a Bell Huey and leaves you, the reader, sweating and with palpitations as if you're actually in the pilot's seat. No fly-by-wire in those days.
Angular momentum is a measure of the amount of rotational motion an object possesses. It is calculated as the product of an object's moment of inertia and its angular velocity.
A helicopter's rotor blades are tilted at an angle, which creates lift as they rotate. This lift force, combined with the angular momentum of the blades, allows the helicopter to stay in the air and move in different directions.
Yes, a helicopter's angular momentum can be changed by altering the speed of the rotor blades or by changing the direction of the blades' tilt. This allows the helicopter to change its altitude and direction of movement.
Angular momentum plays a crucial role in the stability of a helicopter. If the angular momentum is too high, the helicopter may become difficult to control and could even become unstable. On the other hand, if the angular momentum is too low, the helicopter may not have enough lift to stay in the air.
Yes, by adjusting the speed and tilt of the rotor blades, a skilled pilot can use angular momentum to perform complex maneuvers such as hovering, turning, and even flying upside down.
