Possibilities of FAM-C method in diagnosing ship power plants

Abstract

In the paper the FAM-C diagnostic method developed by the Air Force Institute of Technology, Warsaw, is described. The method based on measurements of electric alternator’s frequency modulation, makes it possible to assess the level of usual wear-and-tear of subassemblies and to locate defects during operation of aircraft power transmission systems. A few prototypes of a pocket-size tester based on this method were six years ago produced and practically implemented to indicate the most worn subassembly and its wear and-tear level. Actually, the computerized diagnostic system based on the testers’ results is used. Attempts to experimental application of the FAM-C method for diagnosing some ship power plant devices, are presented and discussed.
