Rapid & Reliable Wheel Inspection
This automated system uses eddy current
to detect aws or damage in aircraft wheels
of all sizes. WheelScan enables operators
to perform inspections faster without
compromising inspection integrity. Setup
and operation is so easy that extensive
training is not required.
Automatic System Increases Speed of Inspection
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.
Rapid Testing
The unit covers the wheel with inspection speeds up to 2 ms-1 (78
inches/second). All inspections are specied 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 arrive 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
HMI Diagnostic Panel
Control System Diagnostic Panel
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, equivalent to approximately 10 million wheel inspection cycles.
Without Compromising the Integrity of Inspection
Accurate
With encoders on all axes, repeat positioning of scan
parameters is guaranteed. The AutoTrak Plus, twodimensional bi-directional contour following system,
ensures that the probe travel path covers 100 % of the
surface. The wheel may be tested ange up, ange
down, fully assembled ange to ange, and can handle
complex proles (e.g., racing car wheels).
Minimizing User Errors
WheelScan 5 provides a variety of methods for entering
and retrieving data. The aim of the unit is to allow the
experienced user total exibility when setting up precision inspections. The ability to “walk” the equipment
through the tests and take settings from the on-board
encoders ensures that measurements are absolutely
precise for each type of wheel. Once the data has been
set up, it can be stored digitally for easy recall in the
future. The recall can even be automated so that the
total test can be recalled with the single scan of a bar
code, and input errors such as the operator ID and
Job References can also be input by bar code. This
removes the need for manual data re-keying, the
most frequent cause of data error in comparable
systems. For added data protection, a key switch
with user/supervisor mode locks out unauthorized
changes.
WhIRS - Wheel Inspection Reporting System
WheelScan 5 has dierent levels of reporting to
meet all your inspection requirements.
• Real Time Charts - the LCD displays real time
charts for easy and convenient test checks.
• Instant Thermal Strip Chart - provides an in-unit
report for each inspection.
• Oine Data Analysis - link a computer to
WheelScan to print a full color report complete
with all inspection parameters. This can be
printed from a laptop situated next to the
unit or from a PC located on another continent.
