Power transmission tracks of various aircrafts usually exhibit different degrees of wear and tear. A diagnostic method based on the measurement of alternator's frequency modulation has been developed at the Air Force Institute of Technology. This method makes it possible to qualify the level of usual wear-and-tear of subassemblies and locate the defects during operation of the aircraft power transmission tracks. Algorithms of a quick and effective analysis of wear-and-tear for particular kinematic couples have been worked out. Basing on this method, a few prototypes of pocket-size testers were produced six years ago. They are combined with the aircraft electric network and indicate the most worn subassemblies, as well as the level of wear-and-tear. At present, the diagnostic system based on measurements taken with these testers and furnished with a suitable computer database would increase the reliability of the whole aircraft systems. Until now, a diagnostic level has been qualified only on the basis of the so-called negative standard power transmission track, with at least one extremely worn-out element, and only for one aircraft type. Theoretical and experimental works go on simultaneously, with the aim to establish a more universal method.
