Research Institution
New technology is needed for sensing and characterizing incipient defects, and assessing the effects of aging in aerospace components. Next generation materials, including nickel-based superalloys that are exceedingly difficult to inspect with existing technology are being adopted by designers and manufacturers. The ability to ascertain the remaining life of a spacecraft component, and develop mitigation procedures to improve safety and reliability, are critical. RMD proposes a revolutionary new imaging technology based on microscopic, solid-state sensors, magnetic imaging and "eddy current mapping". The new nondestructive evaluation (NDE) technology will be used to detect, map and characterize nano-scale cracks and corrosion in superalloys and metallic components. The data will be used to develop an accurate model for the prediction of defect propagation resulting from aging. The NDE technology will improve spacecraft integrity and safety, reduce the cost and complexity of inspection, and characterize incipient defects and defect propagation. It can be used during materials selection and testing and for evaluating components in the field as they age. The technology taxonomy areas addressed by this proposal include: avionics and astrionics, information, materials, sensors and sources, structures, and verification and validation.
