Monitoring the continued health of aircraft subsystems and identifying problems before they affect airworthiness has been a long-term goal of the aviation industry. This project demonstrated a Smart Patch System (SPS) that could be used for the in-service health monitoring of new and existing commercial rotorcraft structures. The objectives of this project were to: (1) Develop, validate, and demonstrate SPS technologies, including advanced software, algorithms, and methodologies for structures and dynamic components to (1) detect fatigue cracks and damages before exceeding critical threshold or incipient failure and (2) characterize fatigue cracks and damages, and (2) Develop preliminary certification compliance requirements and a framework for certification of an SPS that would be integrated into a Health and Usage Monitoring System for fatigue crack monitoring of commercial rotorcraft structures per the guidelines provided in Federal Aviation Administration Advisory Circular 29-2C, Section MG-15. This report describes the work conducted during a 5-year project. It presents the details on the tasks that were conducted toward the development, validation, and potential certification of an SPS for a specific structural application.
