How it Works
The CDB Process Isolate and Solves Vibration Problems
CDB goes far beyond passively monitoring aircraft vibrations. CDB discerns
the root cause of a particular platform's vibration related issues and provides
a dynamic solution to significantly reduce it or completely eliminate it. This
process uses CDB computer vibration analysis tools to gather requisite vibration
information from instrumented drivetrain components. The CDB computer analyzes
this data and creates an "aircraft vibration profile" (AVP) to determine the
specific solution for the individual aircraft.
The concept of operation is simple, there are accelerometers and other sensors
temporarily placed in designated locations along the drivetrain in order to
measure components RPM, vibration level and other data required. The aircraft is
then run on the ground and measurements are taken. Using complex algorithms, the
computer then analyzes the information, calculates a solution, and displays it
to the technician. The technician follows the solutions instructions and takes the
required steps to balance the drivetrain.
After applying the solution, a verification run is performed to confirm the
reduction in vibration. Then, the sensors are removed along with the special
cables and the aircraft is returned to service. The entire process takes an
average of two to four hours for the first balancing run. Subsequent runs
historically take much less time, sometimes as little as 30 minutes.
