Turbine Engine Particulate Ingestion Analyzer

To address the Navy need for a real-time gas turbine engine particulate ingestion analyzer, Physical Optics Corporation (POC) proposes to develop a new Turbine Engine Particulate Ingestion Analyzer (TURPIAN). This proposed technology is based on size separation of particulates in a cascade impactor and chemical analysis by micro-Raman vibrational spectroscopy. POCs unique sensor innovations will enable TURPIAN to measure size, concentration, and chemical composition of ingested particulates in real time in a small, integrable form factor for use on aerodynamically sensitive turbine engines. As a result, this technology offers the capability to provide in-situ data for improved engine performance and operability, which directly addresses the Navy requirements. In Phase I, POC will demonstrate the feasibility of this technology by designing, analyzing, and preparing technical documentation of the system components for building a prototype in Phase II. A benchtop prototype using commercial off-the-shelf components will be used to conduct proof-of-concept benchtop experiments. In Phase II, POC plans to refine the system design and build a complete prototype for performance testing. At the end of Phase II, the TURPIAN is expected to reach Technology Readiness Level (TRL)-5+ and be ready for initial testing at the Navys turboshaft engine test cell.
