i need to understand how how helicopters work,anyone know?

Helicopters stay in the air through the principles of aerodynamics. The rotors on top of the helicopter generate lift by creating a difference in air pressure above and below the blades. This lift, combined with the forward motion of the helicopter, allows it to stay airborne.
The rotors on a helicopter work by rotating at a high speed, creating lift and thrust. The angle of the rotor blades can be adjusted to control the amount of lift and thrust generated, allowing the helicopter to move in different directions.
A helicopter changes direction by adjusting the angle of the rotor blades. Tilting the rotor blades forward or backward causes the helicopter to move forward or backward, while tilting them to the left or right causes the helicopter to move left or right. This is known as cyclic control.
The tail rotor on a helicopter is responsible for counteracting the torque created by the main rotor. This torque, also known as the "spin" of the helicopter, is caused by the main rotor blades rotating in one direction. The tail rotor produces thrust in the opposite direction, keeping the helicopter stable and preventing it from spinning out of control.
A helicopter can hover in one place by using a combination of the main rotor and the tail rotor. The main rotor generates lift, while the tail rotor counteracts the torque and helps keep the helicopter stable. By adjusting the angle and speed of the rotors, the helicopter can maintain a stable hover in one place.
