Abstract
Official abstract text for this publication.
A method and apparatus for determining failure diagnosis of drive systems of rotorcrafts through measuring the spectral characteristics of rotational oscillations and torsional oscillations and steady windup of a drive shaft. Mechanical anomalies of the drive system will alter the spectral characteristics of rotational oscillations and torsional oscillations and steady windup as detected by a pair of variable reluctance sensors in conjunction with a radial grating mounted on the drive shaft.
First claim
Opening claim text (preview).
1 . A system for detecting torsional anomalies of an aircraft during a failure, the aircraft having a first drive shaft and a second drive shaft, the system comprising: a grating coupled to a first interconnection between the first drive shaft and the second drive shaft; a first sensor located in close proximity to first interconnection; and a processor for comparing a spectral analysis of an output of the first sensor. 2 . The system according to claim 1 , wherein the grating comprises: a plurality of teeth extending from the grating.
