Abstract:

A new system for monitoring, analyzing and recording aircraft structural loads is put forth. The sensors are resistance strain gages which feed a differential analog signal to multiplexeranalog-digital converter. The digitized strain levels are read by a microcomputer, analyzed and recorded on a digital, cassette recorder, when fatigue-significant events are detected. Automated data retrieval and preparation with this proposed system should be straightforward and serve to alleviate much of the manual handling now required. Suggestions for future research include the fabrication and testing of a more advanced prototype of the sequential strain monitor system.
