Prime Photonics will refine and demonstrate a FOD detection system on the first stage fan of a F402 engine. The FOD detection system will increase the safety of aircraft operations by providing the ability to identify the occurrence of FOD allowing for remediation of any damage which may have been caused. The FOD detection system is based on the FOCIS? sensor technology, a case mounted optical blade tip timing sensor. The system to be tested includes optical probes, laser instrumentation, data acquisition hardware, and analysis software. Furthermore, the implementation of the sensing system requires minimal modification to the engine. This new capability will enhance the safety and reliability of the AV-8B fleet, and ultimately other aircraft platforms, by providing data which can be used to eliminate engine failures resulting from undetected damage caused by FOD.
