Testing Considerations for Military Aircraft Engines in Corrosive Environments (A Navy Perspective)

This paper describes the considerations given to the testing of aircraft engines intended for use by the United States military (primarily the Navy) in potentially corrosive environments. The origins and intent of the Navy's full-scale corrosion susceptibility test are explored, and the evolution of the test from its early form to the present 1,200-hour program is described in detail. Sample results illustrating the effectiveness of the current test procedure are presented. Also noted are the activities currently underway to improve the test's effectiveness in the face of advancing engine and test equipment technologies.
