TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
This SBIR project delivers an on-board structural health-monitoring (SHM) system with embedded sensors that sense mechanical impedance deviations to flag incipient damage in time to recover from or prevent in-flight failures. This Component Damage Mitigation (CDM) system integrates early damage detection with failure recovery measures such as self-healing fasteners.

Implications of the innovation
Next Generation Air Transport Systems bring increasingly demanding weight and performance needs that encourage aircraft to operate relatively close to their design limits¬óminor structural failure can mean rapid catastrophe. On-board sensing, diagnostic, and damage mitigation capabilities are needed for early correction of incipient damage. However, no practical system exists. We address this deficiency by building on our existing SHM unit and incorporating damage mitigation.

Technical objectives
CDM leverages our work in impedance-based SHM. Our current prototype consists of a single custom electronics board, and is a TRL 5 unit. We have demonstrated field operation in Boeing launch simulation tests and on full-scale wind turbine blades. We propose to integrate our current approach with damage mitigation measures and to create a practical single-chip solution. We include computer modeling that generates virtual data in our sensor validation.

Research description
Phase 1 establishes feasibility for a single-chip approach based on the impedance method, and demonstrates damage mitigation on a model self-healing fastener. Phase 2 completes and validates single chip development, integrates damage detection and mitigation, and delivers an operational unit.

Anticipated results
Phase 1 demonstrates damage detection/mitigation integration and provides a detailed chip roadmap. Phase 2 delivers an operational unit that performs integrated damage detection, monitoring, and mitigation in crucial propulsion system and airframe components.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
There is a major effort within NASA, the FAA, and the military to develop Integrated Vehicle Health Management (IVHM) technology that utilizes SHM information for computer controlled recovery actions aimed at avoiding catastrophe. CDM provides enabling technology for this effort. CDM supports the NASA Engineering and Safety Center by providing tools for independent testing, analysis, and assessment of high-risk projects. CDM applications include on-wing SHM and damage mitigation of various aircraft components including static structures (e.g., containment components, ducts, vanes, nozzles, etc.) as well as rotating components (e.g., disks, blades, and shafts). CDM in situ SHM technology is needed to improve aircraft safety and reliability by verifying structural integrity and nondestructively inspecting, monitoring, and assessing airframes, aircraft systems, and propulsion elements for damage and health. CDM is integrated with damage mitigation and is applicable to the next generation of turbine engines. These advanced propulsion systems will use revolutionary materials and structures. Structures based on such materials must withstand severe stresses and hostile aero-thermo-chemical environments, while weighing less and operating at higher temperatures than current engines.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Non-NASA commercial applications include Homeland Security structural analysis to mitigate threats (preparedness) and assess damage (response), smart structures, and SHM of civil infrastructures, land/marine structures, medical devices, and military structures. Civil infrastructure includes bridges, highway systems, buildings, power plants, underground structures, and windmills. Land/marine structures include automobiles, trains, submarines, ships, and offshore structures. Medical devices include implants and health monitoring devices. Military structures include helicopters, aircraft, unmanned aerial vehicles (UAV) and others. SHM is an emerging industry driven by an aging infrastructure, malicious humans, and the introduction of advanced materials and structures. SHM applications are also driven by a desire to lower costs by moving from schedule-based to condition-based maintenance. Government customers include NASA and the Departments of Defense, Transportation, and Energy. Non-government customers include energy companies, and other crucial-structure custodians. Westinghouse Electric Company (Nuclear Services Division) is our non-government commercialization partner. WEC sees CDM applications in nuclear power plant SHM, and provides engineering and marketing support at no cost. We are also working with Boeing and the United Space Alliance.
