| Description |
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.
