Assembly & Rigging - Project A22 Questions
and Answers
The earliest technique for rotor tracking was: ✔️✔️Flag tracking.
Electro-optical blade tracking was developed in the 1960's by: ✔️✔️Chicago Aerial.
In the process of using tracking methods and measuring vibrations, users found that Perfect
Track: ✔️✔️Rarely produced minimum vibrations.
On turbine engine powered helicopters, the collective pitch stick is synchronized with:
✔️✔️The fuel control unit (FCU).
The anti-torque rotor runs at a speed: ✔️✔️In direct ratio to the speed of the main rotor.
Pushing the left (anti-torque pedal): ✔️✔️Increases thrust, allowing the main rotor torque to
swing the nose to the left.
Rotor blade stations are numbered: ✔️✔️In inches or centimeters.
The three types of weights utilized to balance the rotor blades are: ✔️✔️Mass Balance,
Spanwise and Tracking.
Failure of blades to track correctly causes vibrations, which can result in the following: ✔️✔️All
of the above.
(Damage to parts of the helicopter, reduction of riding comfort, and a loss in blade
performance due to air turbulence made by the rotating blades.)
