1. A method applied to one or more components of a drive shaft of an aircraft, the method comprising:
- obtaining data based on samples of a vibration signal;
processing, by at least one processor, the data to obtain a qualitative and quantitative assessment of a health of the one or more components based on an application of the data to at least one model, wherein processing the data further comprises segmenting the vibration signal into a plurality of segments representative of a revolution of the drive shaft based on a nominal speed of the drive shaft as part of processing the data, resampling the vibration signal segments from constant time based sampling to constant angular based sampling, and averaging the resampled segments as part of processing the data; and
outputting the assessment.

7. An apparatus for use in connection with an aircraft, the apparatus comprising:
-
at least one processor; and memory having instructions stored thereon that, when executed by the at least one processor, cause the apparatus to; obtain data based on samples of a vibration signal; process the data to obtain a qualitative and quantitative assessment of a health of one or more components of a drive shaft of the aircraft based on an application of the data to at least one model, wherein processing the data includes segmenting the vibration signal into a plurality of segments representative of a revolution of the drive shaft based on a nominal speed of the drive shaft as part of processing the data and averaging the segments as part of processing the data; and output the assessment. - View Dependent Claims (8, 9, 10)

11. An aircraft comprising:
-
a drive shaft comprising a plurality of components; a plurality of sensors configured to measure vibration associated with the aircraft; a control computer configured to; sample measurements from the sensors to obtain data; process the data to obtain a qualitative and quantitative assessment of a health of at least one of the components based on an application of the data to at least one model, wherein processing the data includes segmenting the vibration signal into a plurality of segments representative of a revolution of the drive shaft based on a nominal speed of the drive shaft as part of processing the data and averaging the segments as part of processing the data; and output the assessment. - View Dependent Claims (12, 13)
