Abstract

In turbomachinery, engine vibrations play an essential role, since they may lead to a fast component degradation, lowering the performance and ultimately yielding to fatigue damage. For these reasons, there is a high demand for measurement methods to monitor the behavior of the engine shaft adequately. In this experiment, we characterize the shaft behavior of a turbomachine by measuring the blade tip clearance and by converting it to a shaft displacement. To achieve this goal, we have employed two optical displacement sensors and we have applied the full spectrum technique.
