Rotorcraft Flying Menu > Introduction
to the Helicopter > Antitorque Systems Tail Rotor
Most helicopters with a single, main rotor
system require a separate rotor to overcome torque. This is
accomplished through a variable pitch, antitorque rotor or tail
rotor. [Figure 1-3]. You will need to vary the thrust of the
antitorque system to maintain directional control whenever the
main rotor torque changes, or to make heading changes while
hovering.
Figure 1-3. The antitorque rotor produces
thrust to oppose torque and helps prevent the helicopter from
turning in the opposite direction of the main rotor.
