Analytical Redundancy Management Mechanization and Flight Data Analysis for the F-8 Digital Fly-by-Wire Aircraft Flight Control Sensors

摘要

The details are presented of an onboard digital computer algorithm designed to reliably detect and isolate the first failure in a duplex set of flight control sensors aboard the NASA F-8 digital fly-by-wire aircraft. The algorithm's successful flight test program is summarized, and specific examples are presented of algorithm behavior in response to software-induced signal faults, both with and without aircraft parameter modeling errors.
