Abstract:

This Full Authority Fault Tolerant Electronic Engine Control program FAFTEEC was performed under Contract F33615-79-C-2082. The program was a 25-month study to develop design guidance for utilizing redundancy to provide control system architectures capable of very high levels of reliability. The study configured several such systems and evaluated the reliability, cost-of-ownership, weight and implementation. Conclusions of this program were that FAFTEEC goals are obtainable through redundancy and that the resulting system can be obtained at a reasonable cost and weight through dual system advanced technology. Analysis provided by the FAFTEEC allows for the following conclusions to be reached FAFTEEC goals are reasonable, Redundant systems are required, Single string technology is not cost and weight effective, Coverage of dual systems is extremely important, Coverage via software is complex, costly and will not provide 100 percent coverage, and Dual system technology must be included throughout all system components.
