Prime Photonics was founded in 1999 and specializes in advanced sensor systems for military and industrial turbomachinery. The Foreign Object Damage (FOD) Detection System identifies and characterizes compressor rotor blade impacts during engine operation. Military gas turbines on fixed and rotary wing aircraft, and ground vehicles, are susceptible to performance-reducing FOD damage. This patented technology provides real-time on-wing diagnostics, improving operational readiness and reducing costs associated with current schedule-based visual inspection maintenance activities. A prototype was demonstrated in F402 engine testing performed May-July 2017. The company seeks engine companies and Defense program office(s) with engine diagnostic or condition-based maintenance applications for the technology.
The fatigue cracking potential of a propulsion component drives inspection intervals, greatly impacting total ownership cost and operational readiness. Surface cracks are often preceded by subsurface cracking; however there are no practical solutions for performing subsurface inspections on non-ferrous materials in depot environments. This robust patent- pending technology generates three-dimensional (3D) maps of defect geometries and stress fields in non-ferrous materials, allowing the detection of subsurface cracks. With existing Fiber Optic Clearance and Identification Sensor (FOCIS) products being used for gas turbine rotor vibratory stress analysis, Prime Photonics is currently prototyping it’s 3-D Synchronous Magnetic Imaging System (3D-SMIS™) for NDI of non-ferrous materials. Our goal is to transition 3D-SMIS™ into DoD and prime contractor systems for applications that can reduce the frequency of component inspections.
