  Chapter 3: Helicopter Flight Controls › Antitorque Pedals › Heading Control

  Pressing on the left pedal has the opposite effect: the nose of the helicopter yaws to the left and the tail swings right. [Figure 3-6] With the antitorque pedals in the neutral position, the tail rotor has a medium ... positive pitch angle. In medium positive pitch, the tail rotor thrust approximately equals the torque of the main rotor during cruise flight, so the helicopter maintains a constant heading in level flight. A vertical fin or stabilizer is used…

  should also be applied to understanding aerodynamic conditions. If flight envelopes are exceeded, the end results can be catastrophic. LTE is an aerodynamic condition and is the result of a control margin deficiency in the tail rotor. It can affect ... single-rotor helicopters that utilize a tail rotor. The design of main and tail rotor blades and the tail boom assembly can affect the characteristics and susceptibility of LTE but will not nullify the phenomenon entirely. Translational lift is obtained…

  This results in maximum downward deflection of the rotor blade in front of the helicopter and maximum upward deflection behind it, causing the rotor disk to tilt forward. Figure 3-4. The cyclic pitch control may be mounted vertically between ... from a single cyclic located in the center of the helicopter. The cyclic can pivot in all directions. Antitorque Pedals The antitorque pedals, located on the cabin floor by the pilot’s feet, control the pitch and therefore the thrust…

  shafts connected at both ends with flexible couplings. The flexible couplings allow the drive shaft to flex with the tail boom. Figure 1-7. Coaxial rotors. Figure 1-8.

The gearbox at the end of the tail boom provides an angled drive for the tail rotor and may also include gearing to adjust the output to the optimum rotational speed typically measured in revolutions per minute…

  Chapter 2: Aerodynamics of Flight › Hovering Flight › Translating Tendency (Drift)

  Translating Tendency (Drift) During hovering flight, a single main rotor helicopter tends to move in the direction of tail rotor thrust. This lateral (or sideward) movement is called translating tendency. [Figure 2-27] To counteract this tendency, one or more ... following features may be used. All examples are for a counterclockwise rotating main rotor disk. Figure 2-27. A tail rotor is designed to produce thrust in a direction opposite torque. The thrust produced by the tail rotor is sufficient…

  Antitorque Pedals The antitorque pedals are located on the cabin floor by the pilot’s feet. They control the pitch and, therefore, the thrust of the tail rotor blades. [Figure 2-49] Newton’s third law applies to the helicopter ... fuselage and how it rotates in the opposite direction of the main rotor blades unless counteracted and controlled. To make flight possible and to compensate for this torque, most helicopter designs incorporate an antitorque rotor or tail rotor. The antitorque…
