Abstract: The present conference on fiber-optically equipped 'smart' aerospace structures discusses topics in fiber-embedding in materials, the relationship of sensors to signal-processing capabilities, materials evaluation methods, active structural control, and damage assessment Attention is given to the USAF Astronautics Laboratory's smart structures/skins program, on-orbit structural health monitoring, optimal coatings for smart structure fiber-optic sensors, a composite material-embedded fiber-optic Fabry-Perot strain rosette, and the embedding of fiber-optic sensors in Ti-matrix composites Also discussed are neural-network processing of fiber-optic sensors and sensor arrays, the degradation of laminate composites by embedded fiber-optic sensors, a 'smart strut' interferometric differential-strain sensor, shape-memory alloys for flexible structure control, and the optical-signal analysis of impact-induced fracture in smart structures

TL;DR: In this paper, a smart structure diagnostic system for the initial phase of the NASA Space Station Freedom is evaluated, with a view to more complete smart structures implementation in the course of station evolution.
Abstract: On-orbit structural health monitoring aboard space platforms requires the development of sensor systems for assessing impact damage from particles and debris, the effects of atomic oxygen erosion, and the integrity of power systems, storage tanks, pressure vessels, and major structural elements. The task of implementing such a smart structure diagnostic system during the initial phase of the NASA Space Station Freedom is evaluated, with a view to more complete smart structures implementation in the course of station evolution. The data processing/cataloguing task may ultimately require AI and neural networks.
