Over ocean, salt aerosols ingested in the combustion air of a marine gas turbine cause engine compressor fouling and are a primary factor in engine hot section corrosion. To minimize salt ingestion effects on engine performance and life, a high performance salt filtration system is required. The U.S. Navy is currently conducting the Gas Turbine Inlet Development Program. The program consists of work elements including salt filter tests, at-sea salt-in-air measurements, ship aerodynamic studies, inlet duct design, etc. To complete the assigned work tasks, Navy facilities had to develop state-of-the-art instrumentation and test procedures. Based on these work tasks, the U.S. Navy will publish a Gas Turbine Inlet System Design Handbook. The handbook will provide design guidance for the ship builder and inlet duct designer for optimizing shipboard salt filtration perfmance.
