Study Notes
Helicopter Controls
- The collective control is responsible for changing the pitch angle of all main rotor blades simultaneously.
- When the pitch angle on the blades increases, the rotor r.p.m. decreases.
- The throttle control regulates the engine power, thereby affecting the manifold pressure.
Primary and Secondary Controls
- The throttle control is considered to be a secondary control of the collective control's function.
Correlator and Manifold Pressure
- The correlator synchronizes the throttle and collective controls to ensure a consistent manifold pressure.
- The throttle control is the primary control for manifold pressure in piston helicopters.
Antitorque Pedals
- The antitorque pedals are located on the floor of the helicopter.
- The antitorque pedals are used to change the heading of the helicopter during forward flight.
Tail Rotor
- The primary purpose of the tail rotor is to counteract the torque effect of the main rotor.
- The tail rotor thrust is determined by the relative positions of the antitorque pedals.
- The tail rotor can have a positive or negative pitch angle, depending on the direction of the tail rotor thrust.
True or False
- FALSE: The tail rotor is only used to counteract torque of the main rotor.
- FALSE: The antitorque pedals are not used to control the heading of the helicopter in forward flight.
- FALSE: The pitch angle of the tail rotor blades can only be positive or negative.
- FALSE: The tail rotor thrust does not overcome the torque effect of the main rotor during cruise flight if the right pedal is displaced forward of neutral.
- TRUE: The maximum positive pitch angle of the tail rotor is generally greater than the maximum negative pitch angle available.
Forward Flight and Crosswind Takeoffs
- During forward flight, the antitorque pedals are not used to control the heading of the helicopter, except during portions of crosswind takeoffs and landing.
Cyclic Control and Heading
- The cyclic control is used to change heading by making a turn to the desired direction.
- With the right pedal moved forward of the neutral position, the tail rotor either has a negative pitch angle or a small positive pitch angle.
- If the tail rotor has a negative pitch angle, tail rotor thrust is working in the same direction as the torque of the main rotor.
- With the antitorque pedals in the neutral position, the tail rotor has a small positive pitch angle.
