How does a Military Helicopter work_ 2

It generates lift by rotating in a horizontal plane, similar to the wings of an airplane. The angle of attack of the rotor blades can be adjusted collectively (all blades together) and cyclically (individually).

b. Tail Rotor: Many helicopters have a tail rotor, which is mounted on the tail boom perpendicular to the main rotor. The tail rotor counteracts the torque produced by the main rotor, preventing the helicopter from spinning in the opposite direction. It provides anti-torque control and helps stabilize the helicopter during flight.
