On-Line Measurement of the Tip Clearance and Time of Arrival of a Bladed Disk of an Aircraft Engine

Safety and performance of the turbo-engine in an aircraft is directly affected by the health of its blades. In recent years, several improvements to the sensors have taken place to monitor the blades in a non-intrusive way.

Tip clearance - distance between the blade tip and the casing

Time of Arrival (ToA) - passing time at a known position of two consecutive blades

Trifurcated optic sensor
