US Patent:

20180096084, Apr 5, 2018

Filed:

Mar 3, 2016

Appl. No.:

15/567498

Inventors:

- Stratford CT, US
David Kasper - Shelton CT, US
Garrett Argenna - Rochester NY, US

International Classification:

G06F 17/50
G07C 5/08
B64D 45/00

Abstract:

A system and method for determining a remaining useful life of a component, includes providing a usage and configuration information associated with the component, determining if a preexisting spall condition exists for the component, executing a spall initiation model for the component if the preexisting spall condition does not exist, wherein the spall initiation model provides a spall initiation life associated with the component by analyzing the usage and configuration information, executing a spall propagation model for the component, wherein the spall propagation model provides a spall propagation life associated with the component by analyzing the usage and configuration information, and providing a remaining useful life by integrating the spall initiation life and the spall propagation life.

International Classification:

G01M 13/02
G01M 17/00

Abstract:

Embodiments are directed to 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, and outputting the assessment. Embodiments of the disclosure may be applied to one or more components of a drive shaft of an aircraft.

International Classification:

G07C 5/00
B64D 45/00

Abstract:

A method of drive system diagnostics of an aircraft includes capturing high load drivetrain component vibration data at select steady-state and/or high-load transient operating conditions of the aircraft and processing the captured vibration data to improve reliability and/or accuracy of captured vibration data. The processed vibration data is utilized to provide a health assessment of the drivetrain components and achieve earlier detection of incipient faults. A health monitoring system for drivetrain components of an aircraft includes a plurality of vibration sensors positioned at drivetrain components of an aircraft to capture drivetrain component vibration data at transient operating conditions of the aircraft. One or more processing modules process the captured vibration data to improve reliability and/or accuracy of the captured data, and a fault reasoning module calculates a health indicator of the drivetrain components.
