Description

The quantitative capability of CT to measure the relative X-ray linear attenuation coefficient and position of small volume elements in a component also offers the potential to perform center-of-gravity (CG) measurements for rotating systems. Currently, the practice of engine vibration reduction is one of disassembly, iteratively checking balance and grinding off mass until the amount of imbalance is acceptable. This process is labor intensive. An alternative nondestructive method to measure the CG prior to disassembly could provide a cost effective method to minimize the labor effort in balancing operations.
