First Claim
Patent Images
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.

Abstract
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.
