Automatic System Increases Speed of Inspection
Rapid Testing
The unit covers the wheel with inspection speeds up to 2 ms-1 (78
inches/second). All inspections are specied with a constant surface
speed rather than xed RPM, allowing the eddy current lters to give
the best possible performance, irrespective of the amount of wheel
taper. The operator can set up a wide range of helix settings to ar-
rive at the quickest inspection for the required surface coverage. In
addition, the stepper motor drives take the probe rapidly to the start
of the inspection at up to 150 mms-1 (6 inches/second) to minimize
inspection cycle time.
Automatic Wheel Testing
•
The wheel is rst raised on a lift ram to a preset height, spun up to
the required speed, and centered.
•
The probe is then scanned over a test block with a reference notch,
and the probe moves to the scan start.
•
The wheel is scanned at the required scan helix and speed, and the
signals from the probe are recorded.
•
Test results are recorded using a thermal chart or paperless recor-
ding for quality assurance purposes.
•
The probe returns to scan the test block again.
•
If required, the probe can return to the defect for further analysis
for process control purposes.
Teach & Learn
Setup is made easy using a “teach and learn” system. When a new
wheel is encountered, WheelScan stores stop height, start height
and other programmed parameters. The next time that wheel type is
scanned, WheelScan recalls the stored parameters.
Reliable
WheelScan uses standard motion control system components that
promote long life. Its modular construction makes servicing and
replacement of components easy. The ball-screw driven actuators
have a standard life rating in excess of 10,000 km of travel, equiva-
lent to approximately 10 million wheel inspection cycles.

Aircraft wheels are subject to high level cyclic fatigue, particularly during landing. To ensure the safety of
passengers and the aircraft, it is important that the wheels are maintained to the highest standard.
Eddy Current wheel inspection is widely accepted throughout the world as a rapid and reliable means of
maintaining the integrity of aircraft wheels.
