May 26, 2015 – Blacksburg, VA – Dr. David Gray, Prime Photonics Principal Scientist and New Technologies Team Leader, served as a judge at the 73rd Annual Virginia Junior Academy of Science (VJAS) Symposium at James Madison University in Harrisonburg, VA. At the VJAS event on May 21, Dr. Gray reviewed and judged written and oral presentations by middle and high school students from across the Commonwealth of Virginia. This is the second year Dr. Gray has supported VJAS by serving as a judge at the event.
May 18, 2015 – Blacksburg, VA - On April 30th, NASA announced the selection of their 2015 SBIR/STTR awards. Prime Photonics was selected for two awards out of only 50 nationwide. The New Technologies team, under Dr. David Gray, received both of the Prime Photonics award selections and will be working with Dr. John Duke of Virginia Tech to develop novel techniques to gauge residual useful life of structural components and Dr. Shashank Priya of the Center for Energy Harvesting Materials and Systems (CEHMS) of Virginia Tech to develop elevated temperature vibrational harvesters to enable wireless strain measurements for structural health monitoring applications.
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.
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.
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.
