Abstract:
This report for a program to develop a predictive corrosion model for aircraft summarizes the work completed in Task III. The corrosion rate equations and models developed in Task II were converted into a VAX-11 FORTRAN program which enables the analysis of specific points on the C-5 aircraft and, utilizing environmental factors and the time periods an aircraft has been at various Air Force bases, gives recommended times for inspection and maintenance. The FORTRAN computer program includes a crack growth module which calculates the remaining flight hours until a theoretical crack grows to half its critical length, a corrosion module which calculates the remaining hours until exposed aircraft alloys corrode to a depth of 3 mils, and a coating degradation module which computes the optimum time remaining until the next paint renewal or complete repaint operation. Volume I describes the program effort. Volume II contains computer program printouts. Keywords: Corrosion modeling, Maintenance scheduling coating degradation, Predictive corrosion model, Fatigue crack monitoring.
