Abstract
Vibration is an important parameter to judge the safety, integrity and efficiency of an engine installation in any aircraft. Certification authorities usually require proof that the engine installation meets the specified requirements of the engine Original Equipment Manufacturer (OEM). This paper describes a method for vibration measurement and trend analysis of a Light Transport Aircraft (LTA) turbo prop engine. In the process, a transducer mounting bracket is designed and analyzed for mode shapes using commercial software ANSYS and the results have shown that the natural frequency is within the safe limits. Architecture of the data acquisition system and the signal processing are clearly elaborated. The engine vibration level measured for different power settings on the aircraft is within the limits specified by the engine OEM. Thus, the vibration measurement system developed has been successfully meeting the requirement and the data is used for engine health monitoring.
