    1. Propellers and helicopter rotors perform different tasks in different ways. A propeller moves forward through the air while turning in such a way that each strip of the blade meets the oncoming air at an angle that efficiently produces thrust from the torque provided by the motor. Propeller blades are twisted to accomplish that purpose. A helicopter rotor hovers in one place, drawing air down through itself. Helicopter rotor blades are not twisted. Helicopter rotor blades are also much longer and thinner than propeller blades, and of uniform chord.
