Abstract

Availability analysis has been performed on a military turbojet engine using commercially available reliability software. Failure data of the engine over a period of 7 years are considered. The failures/defects are categorized, and then analysis is performed for the major defects. Weibull model is used to analyze the availability of the engine highlighting the possible areas for improvement for the enhancement of engine availability.
