| 3.6. ANTITORQUE ROTOR Figure 3.4 shows the direction of travel for a main rotor, the direction of torque for the fuselage, and the location of an antitorque (tail) rotor.
An antitorque rotor located on the end of a tail boom extension provides compensation for torque in the single-main-rotor helicopter. The tail rotor, driven by the engine at a constant speed, produces thrust in a horizontal plane opposite to the torque reaction developed by the main rotor. |
