Development of Inexpensive Acquisition and Diagnostic Technique for Piston-Engine AircraftThio, Tzer Hwai Gilbert 12 May 2001 (has links)
This paper presents an exploratory study of aircraft engine fault indicators obtained from sound and vibration recordings. Observing time sequence and frequency spectra of the recordings, a simple yet cost-effective method of detecting engine fault is achieved. A detailed discussion of the study performed, ranging from the hardware and software selection, initial tests, and discoveries made in the time domain and subsequently in the frequency domain will be presented.
