Microcomputer based solid state crash data recorder for military aircraft
Albertolli, William Ramon
MetadataShow full item record
The design, breadboard implementation, and functional testing of a Crash Data Recorder for military aircraft is reported. A microcomputer is used to analyze the flight parameters, reduce redundant data, and record only significant information to be used in post-crash analysis. Nonvolatile solid state memory is used as the recording medium. Functional tests indicate that the solid state recorder's reliability is higher than that of mechanical magnetic tape recorders while cost, weight, size, and required maintenance are greatly reduced. The microcomputer provides an expansion capability for future applications of the flight recorder. Research and development, structural history, maintenance analysis, and training are areas where the Crash Data Recorder can also serve as an analytical tool. Continued research in this subject is highly recommended.
