Filmless Radiography for Aerospace NDT

摘要

The purpose of this Phase I Small Business Innovation Research (SBIR) effort wasto examine the suitability of an industrial system of filmless radiography to aerospace applications, and define such a system that would satisfy Air Force needs and requirements. Filmless radiography was applied to the nondestructive evaluation of Air Force aircraft demonstrating cost-effective benefits to routine inspections for foreign objects (FO), moisture entrapment, corrosion, and cracks. Film radiography has become a burden-some, inefficient, and expensive activity, especially in light of hazardous materials concerns. Hazardous materials handling is a significant environmental issue and therefore maintenance and disposition of film processing chemicals and the silver recovery program have become major concerns. Employment of a system of filmless radiography would not only reduce the cost of dealing with hazardous materials, but eliminate it completely.
