Avionics Subsystem Mechanization Analysis and Recommendations.
Abstract
A study was conducted to provide (1) an analysis of avionic subsystem mechanizations, (2) a summary of system mechanization precautions, (3) a tabulation of avionic signal flow, and (4) ground/flight test recommendations. The subsystem mechanization analysis was a determination of the feasibility and extent to which a central multiprocessor could provide functions presently performed within the subsystems. Selected A-7D subsystems and additional conceptual subsystems were examined. It was concluded that virtually all of the functions provided by the Flight Director Computer, Air Data, Computer, NAV/WD Computer, and Terrain Following Computer could be performed by a central processor. The Automatic Flight Control System functions could be handled by a central processor, put the reliability-redundancy-safety questions require further examination. Significant portions of the Head-Up Display, Armament Station Control Unit, and the Laser Spot Tracker could also be provided by a central processor. The mechanization precautions section summarizes perplexities encountered during the integration of the A-7D avionic system. The signal flow tabulation presents the number, type and response of signals utilized in the present A-7D avionic system. Test recommendations were given for an assumed avionic system configuration. A general definition of test equipment and facilities is also included. (Author)
