Prime Photonics presents on engine health monitoring at P-SAR 2015

April 9, 2015 – Blacksburg, VA – Last week at the 2015 Propulsion – Safety and Affordable Readiness Conference (P-SAR) held in Baltimore, Maryland, Prime Photonics presented the latest test results of its FOCIS™-based engine health monitoring system. In the presentation, “Blade Health Monitoring Using Multi-Function Optical Sensors”, Prime Photonics VP of R&D, Dr. Dan Kominsky, reviewed the foreign object damage (FOD) detection capabilities of the system which included testing on gas turbine rotors and blisks ranging from 6.5” to over 41” in diameter. The non-intrusive monitoring system uses FOCIS™ optical probes mounted on the engine casing to detect impact events and blade vibrations. Presented test results showed that in spin rig testing the system has successfully detected the occurrence of FOD events 100% of the time and correctly identified the impacted blade in over 90% of even non-damaging FOD events.
