Abstract

A system designed for failure detectability through detection and isolation of a particular design feature.

Claims

1. A system designed for failure detectability comprising:

a system comprising a multiple of components and a holistic sensor suite, said holistic sensor suite operable to detect an abnormal occurrence of said system, said abnormal occurrence identifiable by said holistic sensor suite through detection and isolation of a particular design feature of each of said multiple of components.

2. The system as recited in claim 1, wherein said system is a gas turbine engine.

3. The system as recited in claim 1, wherein said holistic sensor suite comprises a vibration sensor.

4. The system as recited in claim 1, wherein said holistic sensor suite comprises an oil debris monitoring sensor.

5. The system as recited in claim 1, wherein said multiple of components comprise a multiple of seals.

6. The system as recited in claim 1, wherein said particular design feature comprises a unique color-coded taggants embedded in each of said multiple of components.

7. The system as recited in claim 1, wherein said multiple of components comprise a non-ferrous material component.

8. The system as recited in claim 7, wherein said particular design feature comprises a multiple of mild steel spheroids embedded in each of said multiple of components, said multiple of mild steel spheroids identifiable by said holistic sensor suite.

9. The system as recited in claim 1, wherein said particular design feature comprises a unique alloy for each of said multiple of components.

10. A method of system design for failure detectability comprising:

incorporating a particular design feature into each of a multiple of components within a system; and

identifying an abnormal occurrence with a holistic sensor suite through detection and isolation of the particular design feature.

11. A method as recited in claim 10, further comprises determining the particular design feature in response to increase fault precursor observability to the holistic sensor suite.

12. A method as recited in claim 10, further comprises determining the particular design feature in response to increase fault observability to the holistic sensor suite.
