Abstract
A device to verify tail rotor cross-head positioning is disclosed. The device comprises a first portion and a second portion. The second portion may be adjoined to the first portion and comprises maximum and minimum surfaces configured to determine whether a yoke-measuring surface of a tail rotor yoke may be positioned between respective geometric planes of the maximum and minimum surfaces.
Claims20
A device to verify tail rotor cross-head positioning comprising:
- a first portion;
- and
- a second portion adjoined to the first portion and comprising maximum and minimum surfaces configured to determine whether a yoke-measuring surface of a tail rotor yoke is positioned between respective geometric planes of the maximum and minimum surfaces.
A method of verifying tail rotor rigging of a rotorcraft, comprising:
- determining, using a verification tool, whether a yoke-measuring surface of a tail rotor yoke that is coupled to an actuator using a control tube is positioned between respective geometric planes of maximum and minimum surfaces of the verification tool;
- adjusting the control tube;
- and
- determining, using the verification tool, whether the yoke-measuring surface of the tail rotor yoke is positioned between the respective geometric planes of the maximum and minimum surfaces of the verification tool.
