Wire Health Management for Aeronautics

EWIS Gap Assessment

• Lots of hardware development but little funded development of algorithms for assessing reflections or alternatives to reflectometry.

• Lack of understanding in how electrical signatures change over time with respect to chafing events.

• Lack of publicly available wire fault data libraries. (SBIR IP)

• Lack of rigorous requirements definition.

• Minimal advancement of maintenance tools.

Gaps in national portfolio

• Develop and compare algorithms for detecting and characterizing faults both electrically as well as via effluent detection.

• Simulate and experiment in lab chafing events.

• Provide and host wire fault data library on web.

• Examine trade-space using developed models.

• Development of ultrasonic enabled crimping tool.

NASA’s contribution:

CONCLUSION

• Datasets - Development of publicly accessible electrical signature fault datasets

• Algorithms - Development of algorithms for understanding and characterizing electrical signatures of faults.

• Bayesian Inversion Methods - Development of Bayesian modeling techniques for assessment of fault progression.

• Advanced Maintenance Tools - Development of advanced maintenance tools (ultrasonic wire crimper).

• New NDI - Development of new NDI techniques such as detection of effluent.

Policy Principles

1. Mobility through the air is vital to economic stability, growth, and security as a nation

2. Aviation is vital to national security and homeland defense

3. Aviation safety is paramount

4. Security of and within the aeronautics enterprise must be maintained

5. The US should continue to possess, rely on, and develop its world-class aeronautics workforce

6. Assuring energy availability and efficiency is central to the growth of the aeronautics enterprise

7. The environment must be protected while sustaining growth in air transportation

The National Aeronautics R&D Policy and the follow-on Implementation Plan lay out the roles and responsibilities of participating federal agencies, including NASA, in a collaborative effort to advance U.S. technological leadership in aeronautics. In the Council’s view, the NASA Aeronautics program, while currently conducting high quality research, is not funded at a level sufficient to achieve the leadership objectives implicit in the National Aeronautics R&D Policy. In the Council’s judgment, the NASA Aeronautics Program should at least be doubled over a five-year period in order to meet these objectives.

Observation

Systems-level research projects with discrete start and end dates should be considered in addition to and as an augmentation of the existing funded effort. Background: Systems-level research projects would not raise the budget runout level in perpetuity and should be focused on areas where NASA has unique demonstrated expertise in line with the National Aeronautics R&D Policy. Systems-level research is in contrast to validation and demonstration of point designs.

Recommendation

Requested from NASA ARMD• Specific candidates for systems-level

research projects• Technical details of the meeting of the

Thermal Protection Systems Working Group

Next Meeting Plans• Receive an update on activities at NASA

and DoD in Thermal Protection Systems
