How do rotor helicopters work?
Rotor helicopters work by generating lift through the rotation of large horizontal blades called rotor blades. As the rotor blades rotate, they create a pressure difference between the top and bottom surfaces of the blades, producing lift. By altering the pitch of the rotor blades and controlling the speed of rotation, pilots can steer the helicopter in different directions.
