April 13, 2015 – Blacksburg, VA – Prime Photonics hosted a field trip for New River Community College (NRCC) students in the electronics curriculum. As a part of the Electronics Technology Degree Program at New River Community College, students have the option to enroll in a class on the theory and application of lasers and fiber optics. Malcolm Laing, Product Engineer, presented a brief overview of optical sensing techniques before leading a demonstration of the Prime Photonics Foreign Object Damage (FOD) detection and gas turbine blade health monitoring system.
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.
March 23, 2015 – Blacksburg, VA – Prime Photonics Principal Scientist, Dr. David Gray, served as an expert panelist at the 2015 Virginia Tech Drillfield Series presentation, “What Fuels Our Planet” at the Holtzman Alumni Center Saturday, March 21. The Renewable Energy Panel, moderated by Prof. Shashank Priya of the Center for Energy Harvesting Materials and Systems (CEHMS) at Virginia Tech, discussed how technology advancements are creating new opportunities to harness alternative energy sources, and how developments at Virginia Tech have the potential to change local communities and the world.
March 27, 2015 – Blacksburg, VA – Prime Photonics will be attending and exhibiting at the Propulsion – Safety and Affordable Readiness Conference held March 30 – April 2 in Baltimore, Maryland. The P-SAR Conference highlights recent advanced turbine engine technologies that will have significant impacts on reducing engine related Class A mishaps, reducing maintenance costs and increasing average time on wing. In the technical conference, Dr. Dan Kominsky, VP of R&D, will be presenting recent test results from the Prime Phonics foreign object damage (FOD) detection and blade health monitoring program.
November 10, 2014 – Blacksburg, VA – Prime Photonics exhibited its FOCIS™ gas turbine blade sensor product line at the joint PIWG/EVI-GTI conference held in Hasbrouck, New Jersey, October 20-24. The bi-annual joint meeting and conference held by the Propulsion and Instrumentation Working Group (PIWG) and its European counterpart, the European Virtual Institute for Gas Turbine Instrumentation (EVI-GTI), provides a forum for engine companies, United States Department of Defense, United States Department of Energy, university researchers and suppliers, to discuss new gas turbine instrumentation products and technology, future measurement needs in the industry as well as gas turbine sensor standards activities. At the PIWG/EVI-GTI meeting, Prime Photonics’ Products and Applications Lead Malcolm Laing presented the FOCIS™ sensor product line and also discussed upcoming additions to the product line, including a higher temperature Blade Tip Timing (BTT) probe and new probe configurations. Prime Photonics has been a member of the PIWG Steering and Advisory Board since 2010 and is a member of multiple PIWG-driven standards efforts including ISA 107.1: Tip Timing for Use in Gas Turbine Engines.
