Abstract
A method for detecting angle sensor performance degradation in a flow angle measurement device in moving platform, such as aircraft and watercraft, as well as stationary platforms. Sensor dither in a flow angle measurement device is used to detect operational performance degradation of the sensor as a result of dynamic response changes caused by damaged or degraded mechanical components.
Claims23
A computer-implemented method for detecting sensor performance degradation in a fluid flow angular measurement device, the method comprising the steps of:
- monitoring oscillation characteristics of a fluid flow measurement device in a computer processor;
- and
- determining if the fluid flow measure device is physically damaged based upon referenced sensor dither characteristics for the fluid flow measurement device as determined by a computer processor based upon the monitored oscillation characteristics of a fluid flow measurement device.
A computer program product comprising a computer useable medium having control logic stored therein for detecting sensor performance degradation in a fluid flow angular measurement device, said control logic including comprising computer readable program means for causing a computer to monitor oscillation characteristics of the fluid flow measurement device and determining if the fluid flow measurement device is physically damaged based upon referenced sensor dither characteristics for the fluid flow measurement device based upon the monitored oscillation characteristics of the fluid flow measurement device.
